Gartner: Top 10 cloud storage providers #top #cloud #computing #providers


Gartner: Top 10 cloud storage providers

According to a Gartner survey. about 19% of organizations are using the cloud for production computing, while 20% are using public cloud storage services.

That means there’s a pretty good sized market for the cloud, and specifically cloud storage. Gartner predicted in 2012 $109 billion was spent on cloud computing. a 20% increase from the year before.

But the cloud is a big industry too, with a lot of vendors seemingly having a cloud strategy today. So where do potential customers start? Recently, Gartner released a list of the top 10 cloud storage providers, based on enterprise capabilities. Below is a description of each, based on pros, cons, strengths and weaknesses.

Amazon Web Services

Like many other aspects of cloud computing, Amazon Web Services is considered a market leader in cloud storage. It’s been an early and aggressive player in the market and its services drive offerings from competitors, Gartner says, while its pricing is the “industry reference point.” Its Simple Storage Service (S3) is the basic object storage, while Elastic Block Storage is for storage volumes. AWS keeps innovating too. Earlier this year AWS announced Glacier, a long-term, low-cost archival storage services. More recently, at its first-ever user conference, AWS announced Redshift, a cloud-based data warehousing service.

AWS has challenges though, Gartner notes. While it has a tool to link on-premise data to its cloud, named AWS Storage Gateway, the ability to create hybrid storage architectures that span both on-premise storage options and AWS’s cloud is still largely a work in progress, Gartner says. AWS is an innovative company that continues to release products and services to round out its already-market leading position though. With services geared to specific vertical industries, most notably the federal government agencies with its GovCloud service, it has a wide breadth and depth of cloud storage features and services.

AT T’s Synaptic cloud storage service is aligned closely with EMC’s Atmos storage service, which is used as an on-premise storage system. This creates an opportunity for AT T to sell into the strong EMC customer base, and gives customers hybrid cloud capabilities with a leading storage vendor. Gartner says this has been focused mostly on small and midsized businesses though. Still, AT T claims it has recorded double-digit growth in its service, with several billion objects stored in its cloud. AT T Synaptic already spans multiple regions, which customers can choose to take advantage of, with plans by AT T to expand the service globally, with Europe being the next stop. Customers using AT T’s VPN service are freed from ingress and egress charges when using the company’s cloud service.

Google Cloud Storage

Launched in 2010, Google Cloud Storage is the underlying storage service for the company’s other cloud products and services, including Google App Engine – the application development platform – Google Compute Engine, and BigQuery, which are cloud-based virtual machines and a big data analysis tool, respectively. Customers access Google Cloud Storage through a restful API and the service is available in both the U.S. and Europe. Holding the company and its cloud storage platform back though is a relative lack of significant sales and support targeted at enterprise customers, Gartner notes. That leaves Google Cloud Storage ideally suited for sophisticated customers willing to set up and manage the deployment, and specifically developers looking for large storage capacity for Google applications.

HP announced the public beta of its cloud storage platform debuted in May of 2012 and it’s meant to work in tandem with both its compute and content delivery network (CDN), which it recently partnered with Akamai on. The storage platform is based on OpenStack technology and HP offers free 24/7 call and chat support on top of 99.95% availability guarantees. “Among OpenStack-based cloud storage providers, HP is well-positioned to understand enterprise IT storage requirements, due to its extensive hardware, software and service offerings,” Gartner notes. “However, since HP Cloud Object Storage is new, HP must evolve and refine its architectural, geographical and service offerings.” The system automatically replicates data across three availability zones for resiliency (which customers can choose to do in Amazon’s cloud), and HP says having information running on its hardware both in the public cloud and on customers’ premises makes for easy hybrid cloud setups.

IBM’s cloud storage is part of its SmartCloud Enterprise offering, which includes other services such as cloud-based application development and infrastructure. Gartner says the biggest deficiency is the lack of integration among the various aspects of IBM’s SmartCloud offering though. For example, IBM markets its cloud for backup and recovery, but those services do not use IBM SmartCloud Object Storage on its backend. Part of this could be because IBM partners with Nirvanix, another cloud storage provider, to run the SamrtCloud Object Storage. The disparate nature of these services under the IBM SmartCloud umbrella could create “silos of capabilities” for various services, Gartner warns. But, IBM has committed to more tightly integrating its products and services together. Its experience in selling to major IT enterprise shops gives it a significant advantage in becoming a major player in the large enterprise cloud storage market.

Internap’s history is as a managed service and collocation provider, but it has more recently emerged as a cloud player as well. Its AgileFiles cloud storage system is based off of the OpenStack Swift storage platform and is available in the U.S. Europe and Asia, with plans for future expansion. To differentiate its service, Internap has attempted to layer on advanced networking features to the service, such as a Manager Internet Route Optimizer (MIRO), which analyzes the performance of the possible routes to deliver content and chooses the best one. Gartner says its lack of enterprise presence is the biggest limitation holding the company back.

Behind Amazon Web Services, Microsoft’s Windows Azure Blob Storage may be the second most widely-used cloud storage service, Gartner predicts. It now boasts more than a trillion objects and is growing at 200% per year, Gartner says, while supporting a broad range of features including object storage, table storage, SQL Server and a content delivery network (CDN). Azure’s Blob storage is in a pricing “race to the bottom,” with Amazon, Google and Microsoft each dropping prices consistently during the past year to offer the most competitive prices among the three competitors. Gartner calls Microsoft a “fast-follower” of feature roll outs behind Amazon as well. Its tiered support options are appealing to large enterprise customers, Gartner says, providing customers a hands-on fee-based support team. Microsoft has bulked up its storage chops too by recently purchasing cloud storage gateway vendor StorSimple.

A pure-play cloud storage provider, Nirvanix is solely dedicated to this market. Gartner says that’s great for companies looking for data-intensive storage needs, but could be a drawback for customers looking for an all-inclusive vendor that would provide compute services on top of a storage platform. Nirvanix has some appealing characteristics though, including the ability to have public, hybrid or on-premise Nirvanix-powered storage services, and an all-inclusive monthly billing cycle with premium support options, a clear aim for enterprise customers, but one that may turn away small and midsized businesses that may prefer the a la carte pricing.

Rackspace is another major player in the cloud storage ecosystem, with its Cloud Files service augmented by a robust set of accompanying services, including compute infrastructure and a CDN network powered by Akamai. For high-performance storage needs, it has Cloud Block Storage, which has high input-output capabilities. Rackspace works heavily on the OpenStack open source project and its services closely follow OpenStack developments. Because of its work in the OpenStack environment, Gartner says Rackspace public cloud storage services integrate nicely with OpenStack-powered on premise clouds, creating hybrid cloud services for customers.

Softlayer’s Cloudlayer object storage system is based on the OpenStack Swift platform that accompanies a range of other services offered by Softlayer, including compute and CDN. Softlayer also has a storage-area network (SAN) offering and an international presence, with data center locations in its headquarters of Dallas, along with Amsterdam and Singapore. Its lack of support and turnkey deployment cycles, Gartner says, has meant that the product has not caught on wildly with the enterprise market yet though.

Fiber Optic Installation – Inspection and Copper Cable Testing Tools #it


Punch Down and Termination Tools

The best installations start with the best tools. And you can get the best tools from one trusted provider – Fluke Networks. Our network installation line encompasses all the essential tools needed for a job done right! From our innovative JackRapid™ punchdown tool to our forged steel constructed D-Snips cable scissors, look to Fluke Networks.

Case Studies

ITM, a UK-based leading independent provider of specialist ICT infrastructure solutions and services, applies best of breed technology, in-house expertise and innovation to deliver standards compliant solutions and services to clients throughout the UK, Europe and the rest of the World. Stuart Ayres, ITM Fibre & Equipment Engineer, reviewed the results of their investment in twenty Versiv Cabling Certification Systems.

After using the Versiv System for a few months it clearly offers several advantages when compared to the previous generation of test equipment. Not only is the Versiv System faster, the modular design and online connectivity dramatically reduces our engineers travel time as they no longer need to call into the office to have test results downloaded or firmware updated.

During the few months that we have been using the new equipment I have identified the following advantages that translate into productivity gains for both ITM and our Customers:

  • Greatly reduced test cycle times for both copper and fibre.
  • Easy and fast movement of test data from site to office enables better project progress reporting, quicker sign-off and invoicing.
  • Ability to remotely configure and control the test units.
  • Simplified logistics, we now only have to maintain one fleet of modular multi-purpose test equipment.

The Ultimate Test in the Alaskan Bush Survival Tip: Take care where the bears roam

Integrity Networks provides communications services and cable and fiber network infrastructure installation for companies and federal, state and local governments nationwide and around the Pacific Rim. Based in Renton, Washington, their projects range from military bases in Guam and Singapore, data center and VOIP installations in Washington and Virginia, to major healthcare and corporate oil, gas and mining projects across Alaska.

Integrity Networks entered the Alaskan market in 2007, and it has remained a steady presence in low-voltage contracting there ever since. With branch headquarters in Anchorage, Integrity Networks has an extensive staff of highly skilled Alaskan employees that work on jobs in the last great American frontier.

EXTREME DANGER: High Voltage Environment

With Fluke Networks OptiFiber® Pro OTDR with SmartLoop™, Twistnet technicians safely completed bidirectional certification of new North Sea Wind Farm installation

Established in 2000, with more than 30 years of experience, Twistnet Communications Ltd. specializes in the installation, testing and certification of fiber optic cabling, structured cabling systems and voice cabling systems.

Twistnet Communications Ltd serves companies in the United Kingdom and Europe with core services and it offers experts in fusion splicing, direct fiber termination, OTDR and power-meter testing and certification and repair with state of the art equipment such as the Fluke Networks’ OptiFiber Pro OTDR with SmartLoop, part of the Versiv™ line, the industry’s leading Cabling Certification System

By leveraging Versiv DSX-5000, CertiFiber and LinkWare Live, PowerCom has significantly reduced the time and effort needed to test the systems and provide results to their customers.

Challenge: PowerCOM installs and services a wide range of information and communication systems including; voice, data, Wi-Fi, security and monitoring at a variety of both indoor and outdoor locations. With over 80% of employees working in the field on multiple client sites, delivery of test results to the PowerCOM office and/or client is often challenging. Historically, the process to set up test equipment and compile results has been manual and time intensive for both field and administrative staff. Additionally, some customers desired more frequent and periodic delivery of detailed test results, rather than only upon project completion. To address these issues, PowerCOM required a solution that could help their technicians and administrative staff be more efficient, as well as readily and more easily share data with their customers.

Results: By leveraging Versiv™ DSX-5000, CertiFiber® Pro and LinkWare™ Live, PowerCom has significantly reduced the time and effort needed to test the systems and provide results to their customers. Instead of requiring the field technicians to set-up test parameters and commute to the office to deliver/review the test reports, these tasks can be done remotely through the cloud. By leveraging LinkWare Live, PowerCom technicians can complete jobs faster, ensure test accuracy and reduce the potential for rework.

Fluke Networks is pleased to announce that ECR Informatique, a leading company in the cable installation market, acquired the new Versiv platform, now with a fleet of 7 cable certifiers with DSX-5000 replacing DTX-1800 in order to consolidate its position and deployment in structured cabling solutions systems at both DataCenters and horizontal cabling levels.

Created in 2001 and located in Calvados (France), ECR specializes in cable installation of all types of local area networks (copper, fiber, wireless, laser) in standard or special environments or subject to manufacturers certifications. ECR acts on behalf of businesses, local communities, public and private institutions (education, health. ) on their main site or remote facilities, and is also a subcontractor for major clients taking charge of large scale projects featuring local networks

Financial Case for Moving to the Cloud #cloud #computing #costs, #smarter


The Financial Case for Moving to the Cloud

Many organizations are slow to adopt cloud computing due to confusion around the financial impact of its implementation and management.

Despite the hype, the uptake of cloud computing as a solution has not been as rapid as first anticipated, in part because of the confusion created around the financial benefits, said Sanil Solanki. research director at Gartner. While it s said to be cheaper than on-premises, cloud gets push-back from the finance function because it increases operating expenditure (opex) costs. IT departments let finance take the lead on this decision, and this stalemate is rarely broken.

Ahead of the Gartner IT, Financial, Procurement Asset Management Summit 2015, September 21-22, in London, U.K.. Mr Solanki, said that while using cloud computing does increase opex costs, CIOs should consider other financial factors before making a decision.

CIOs who have a rounded view of the financial impact of cloud are more likely to have progressive discussions with their finance business partners about when and how to deploy cloud services. Understanding the outcomes cloud computing can support is crucial for IT leaders when having these discussions (see Figure 1). Adopting the cloud can save significant amounts of money, which ultimately is the lifeblood of any business.

Figure 1.Gartner s Definition of Cloud Computing

Gartner has outlined the positive and negative financial considerations of cloud computing.

Three positive financial aspects of cloud:

  • Greater cost agility withinfrastructure as a service — Cloud services have a high degree of cost variability, so expenses can quickly go down if demand for services is reduced.
  • Increased retained cash — By using cloud/on-demand services, CIOs do not have to invest upfront to buy IT infrastructure via regular refresh cycles.
  • Reduced opportunity costs — Opportunity costs are defined as the value foregone by pursuing a certain course of action. By choosing to use cloud/on-demand, a company can free up cash to invest in other parts of the business.

Three negative financial aspects of cloud solutions:

  • Less cost agility withsoftware as a service(SaaS) — SaaS providers are promising cost agility as one of the benefits; in reality, however, this is only working one way — up. Clients can end up paying more if they use more licenses, but not less if they don t use as many.
  • Higher subscription fees — The total cost of ownership may be lower over five years, but the subscription fees are more than the perpetual licenses after year three or four; therefore, the savings need to be significant and ongoing to make cost lower after more than five to seven years.
  • High switching costs with SaaS — The cost to get data out and bring it back on-premises is high.

What is Enterprise Cloud Computing FAQ? Definition from, characteristics of cloud


Enterprise Cloud Computing FAQ

Characteristics of cloud computing

  • Share this item with your network:

augmented reality

Augmented reality (AR) is the integration of digital information with live video or the user’s environment in real time.

What is cloud computing?

The U.S. National Institute of Standards and Technology provides the most neutral definition of cloud computing. “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three delivery models, and four deployment models.”

What is enterprise cloud computing?

Enterprise cloud computing is the special case of utilizing cloud computing for competitive advantage through breakout opportunities both for cost savings and, more importantly, for business innovation in terms of unprecedented speed and agility with vastly improved collaboration among business partners and customers. What does “cloud computing” mean for the enterprise? More important than the question of “what is it?” is why it matters. Here are three key points.

1) On the cost side of the equation, many, but not all, IT and data center costs can be reduced and tied directly to usage, up or down as needs go up or down (rapid elasticity).

2) But there’s more, much more, on the revenue side. Risk and startup expenses for innovation initiatives can be cut dramatically, letting companies take more small bets and test out more new ideas. With no upfront capital expense, new projects can be scaled up instantly if they take off, or shut down quickly if they fail. Massive scalability and up-or-down elasticity give companies a whole new sandbox for testing new business ideas and growing them if they take off.

3) Companies don’t work alone, and, on average, over 20 companies make up today’s value chains. Cloud computing allows a company to collaborate in new ways with its trading partners, and collaboration is the key to gaining competitive advantage across the value chain. By establishing shared workspaces in “Community Clouds” employees from multiple companies can work together as a “virtual enterprise network” and function as though they were a single company. They all participate in the same value delivery system, sharing computing, communication and information resources. This is especially important as no one company “owns” the overall value chain.

Is cloud computing new?

Cloud computing is not a new technology or architecture or methodology. But it is a new Information Technology “delivery model” where all computing and networking resources are delivered as “services” that are elastic (use as much or as little as you need at any given time), massively scalable, and are available on-demand with self-service, pay-as-you-go variable cost subscriptions.

What’s driving enterprise cloud computing?

For sure, cost savings represent a significant driver. But far more important are the changes going on in the larger world outside of the business world in our hyper-connected global society. With the advent of easy-to-use “Consumer IT” or Web 2.0 usage of the Internet, Social Networks are changing the ways we live, learn, collaborate, work, consume and play. These huge changes in society also disrupt the way we design and manage our organizations and our value chains that deliver value to customers.

What is a Service-Oriented Enterprise?

What really differentiates a Service-Oriented Enterprise (SOE) from a traditional business model is its “outside-in” approach. A SOE creates business-driven value by defining and exposing its core business processes to the external market through the use of open technology in the form of “services.” This reorganization includes new business requirements, new operating zones and new license structures that can enable improved collaboration between organizations and their customers and suppliers. A SOE has the capability to organize its responses to market shifts due to the agility within its culture, processes and IT systems.

What is Business Technology?

The term Business Technology (BT) is frequently used to describe new technologies such as Web 2.0 and their use in business to differentiate them from the tools and techniques of traditional Information Technology (IT). The key differentiation between BT and IT centers on decentralization and unstructured environments. Organizations still need the centralized and structured role of IT to 20 Enterprise Cloud Computing provide back office functionality, but BT is an additional layer focusing on the front office and customer-facing business activities.

Is cloud computing the same as Software-as-a-Service(SaaS)?

While SaaS vendors originally did not use the word “cloud” to describe their offerings, analysts now consider SaaS to be one of several subsets of the cloud computing market. With traditional SaaS offerings, a company is buying pre-packaged “canned” software applications (e.g.,ERP, SCM or CRM packages) that are hosted remotely, usually in a multitenancy environment, and accessed via the Internet. SaaS applications can become “participants” in unique end-to-end business processes (see BPMaaS).

What is Business Process Management as a Service (BPMaaS)?

With SaaS offerings, a company is buying “same-old” pre-packaged software, but BPMaaS goes far beyond canned “business software as usual” being put online. It goes on to creating unique business processes designed for unique and specific purposes to link together multi-company value delivery systems that in the past weren’t feasible or economical to join together. BPMaaS is all about the complete management of business processes, and puts business people in charge of their processes. In many ways, BPMaaS is what sets enterprise cloud computing apart from consumer cloud computing. Unique business processes are how companies differentiate themselves, and are thus paramount to the enterprise use of cloud computing for competitive advantage. BPMaaS covers the full lifecycle of business processes, from their conception, design implementation and optimization. Bringing BPM capabilities to the Cloud enables multiple companies to share a common BPM system and fully participate in an overall end-to-end business process.

What are the economics of cloud computing?

Cloud computing brings immense economies of scale to computing and delivers computing resources on-demand in much the same way utilities deliver gas and electricity. In the past, companies had to make ever-growing capital expenditures (CAPEX) in comEnterprise Cloud Computing 21 puting resources to implement new information systems. Furthermore, to accommodate potential peak loads, they installed huge amounts of capacity so that today only 10-15% of data center capacity is typical utilized. The shift to the on-demand model of cloud computing isn’t just about cost savings. Far more important, it’s about giving organizations the agility they need to act quickly on new opportunities without IT being on the critical path. “Fast to market” is a central economic variable and speed is essential in the world of total global competition.

What’s the difference between “cloud computing” and “cloud services?”

In short, everything. “Cloud computing” implies a framework and vocabulary aimed at technology semantics. “Cloud services” implies a framework and vocabulary aimed at business semantics. While cloud computing belongs to the domain of Information Technology (IT), cloud services belong to the domain of Business Technology (BT). In other words, cloud services are about business, while cloud computing is about technology. The focus of this book is on the domain of business.

Apple and the cloud: A magnificent missed opportunity #apple #cloud #computing


Apple and the cloud: A magnificent missed opportunity

One of the saddest documents you’ll ever see is prosaically titled DEFENDANT’S EXHIBIT NO. 489.245. (I’ve shared it in a public folder at OneDrive, so you can click that link and read the whole thing at your leisure.)

The document, a printout from an internal email sent to a list of top Apple executives, emerged last month as part of the landmark patent infringement suit brought by Apple against Samsung.

The email was part of a thread that begins with a painfully ironic DO NOT FORWARD warning from Apple Senior Vice President Phil Schiller. It includes the forwarded text of a blunt agenda from Steve Jobs covering Apple’s plans for its 2011 fiscal year.

The dateline alone is poignant. Written in October 2010, the email represents Steve Jobs’ final opportunity to provide his guidance on Apple’s future. Jobs resigned 10 months after this email was sent and died of cancer two months after that.

But the even sadder part is how thoroughly Apple has so far failed to deliver on one of the key goals Jobs laid out in this, his final strategy document. Jobs wanted 2011 to be the “Year of the Cloud.” With the digital hub moving from the PC to the cloud, he said, Apple was “in danger of hanging on to [the] old paradigm too long.”

That summary by Steve Jobs is puzzling. On the one hand, as Apple’s Disruptor-in-Chief, he knew full well how important it is to disrupt your own business before you let someone else do it. He also recognized that both Google and Microsoft had a significant lead in cloud technology, even if they hadn’t figured out how to translate that technology into income or profits.

But on the other hand, Jobs also remained firmly wedded to Apple’s walled garden. His directive in this memo, which was never intended to be seen by us mere mortals, is extraordinarily blunt: “tie all of our products together, so we further lock customers into our ecosystem.”

So, three and a half years later, how far have Apple’s cloud efforts progressed? Compared to the leaders in the cloud ecosystem, not very far at all.

Apple’s iCloud is, first and foremost, a backup target for iOS devices, a job it does reasonably well. But on every other modern yardstick for cloud computing it falls short. My colleague Jason Perlow (disclosure: he now works for Microsoft) has done an excellent job of summing up the cloud landscape in a pair of posts:

Both posts are must-reads. Here’s my current take on Apple’s cloud status:

what’s hot on zdnet

In short, Apple is in no danger of becoming a “devices and services” company anytime soon. What it offers is fine for anyone fully committed to Apple’s hardware. But as soon as you stray into Android or Windows devices, things get. complicated.

Fortunately for Apple and its shareholders, the installed base of Apple hardware, especially iPads and iPhones, is too big for any cloud player to ignore. That position, as gatekeeper to the wealthiest segment of the PC and mobile hardware market, gives Apple an enviable position as power broker.

And in the current climate, that’s a potentially tremendous edge for Microsoft over Google. Office for iPad was an unqualified hit last month, and Microsoft has been aggressively developing its other products, including OneDrive, for iOS. Despite friction through the years, Apple and Microsoft have maintained a working partnership.

Meanwhile, Google, largely on the strength of its Android OS, remains public enemy #1 for Apple. The spate of lawsuits by Apple against Samsung and other Android handset makers are really part of a proxy war against Google. And indeed, if you look just a few lines earlier on the first page of this strategy document, you’ll see the heading “2011: Holy War with Google.”

Under those circumstances, especially with the Mac-PC wars mostly in the rearview mirror, it’s easy to see Apple developing tighter ties with Microsoft’s cloud.

From floppy disks to CDs to USB flash drives, file saving and sharing has undergone a significant evolution over the past decades. The devices to share files are becoming smaller and have higher capacities, increasingly destined to serve an on-the-go lifestyle.

Today you no longer need to save all your documents on one particular device. Instead, you can access your files from any terminal at any time, thanks to cloud computing.

What Is Cloud Computing?

The cloud has always been a metaphor for the Internet; in fact, cloud symbols are often used to portray the Internet on diagrams. As a virtual space that connects users from all over the globe, the Internet is like a cloud, sharing information by way of satellite networks.

Sharing and Storing Data

Cloud computing, in turn, refers to sharing resources, software, and information via a network, in this case the Internet. The information is stored on physical servers maintained and controlled by a cloud computing provider, such as Apple in regards to iCloud. As a user, you access your stored information on the cloud via the Internet.

By using cloud storage, you don t have to store the information on your own hard drive. Instead, you can access it from any location and download it onto any device of your choice, including laptops. tablets. or smartphones. Moreover, you can also edit files, such as Word documents or PowerPoint presentations, simultaneously with other users, making it easier to work away from the office.

There are different types of cloud computing services available to suit different needs. While some cater to individual users who want to store photos, documents, and videos, others are destined for companies that need extensive platforms to develop IT applications, for example.

Depending on your needs, the prices will vary. As an individual user, you can get an initial amount of storage for free, such as 5GB with iCloud. If you need additional storage, you will have to pay a fee. Fees are usually set at monthly or yearly rates, depending on the services you are using.


  1. Worldwide Access. Cloud computing increases mobility, as you can access your documents from any device in any part of the world. For businesses, this means that employees can work from home or on business trips, without having to carry around documents. This increases productivity and allows faster exchange of information. Employees can also work on the same document without having to be in the same place.
  2. More Storage. In the past, memory was limited by the particular device in question. If you ran out of memory, you would need a USB drive to backup your current device. Cloud computing provides increased storage, so you won t have to worry about running out of space on your hard drive.
  3. Easy Set-Up. You can set up a cloud computing service in a matter of minutes. Adjusting your individual settings, such as choosing a password or selecting which devices you want to connect to the network, is similarly simple. After that, you can immediately start using the resources, software, or information in question.
  4. Automatic Updates. The cloud computing provider is responsible for making sure that updates are available you just have to download them. This saves you time, and furthermore, you don t need to be an expert to update your device; the cloud computing provider will automatically notify you and provide you with instructions.
  5. Reduced Cost. Cloud computing is often inexpensive. The software is already installed online, so you won t need to install it yourself. There are numerous cloud computing applications available for free, such as Dropbox. and increasing storage size and memory is affordable. If you need to pay for a cloud computing service, it is paid for incrementally on a monthly or yearly basis. By choosing a plan that has no contract, you can terminate your use of the services at any time; therefore, you only pay for the services when you need them.


  1. Security. When using a cloud computing service, you are essentially handing over your data to a third party. The fact that the entity, as well as users from all over the world, are accessing the same server can cause a security issue. Companies handling confidential information might be particularly concerned about using cloud computing, as data could possibly be harmed by viruses and other malware. That said, some servers like Google Cloud Connect come with customizable spam filtering, email encryption, and SSL enforcement for secure HTTPS access, among other security measures.
  2. Privacy. Cloud computing comes with the risk that unauthorized users might access your information. To protect against this happening, cloud computing services offer password protection and operate on secure servers with data encryption technology.
  3. Loss of Control. Cloud computing entities control the users. This includes not only how much you have to pay to use the service, but also what information you can store, where you can access it from, and many other factors. You depend on the provider for updates and backups. If for some reason, their server ceases to operate, you run the risk of losing all your information.
  4. Internet Reliance. While Internet access is increasingly widespread, it is not available everywhere just yet. If the area that you are in doesn t have Internet access, you won t be able to open any of the documents you have stored in the cloud.

Popular Cloud Computing Services

  • iCloud. Apple s iCloud allows you to store music, documents, photos, and other files via WiFi. You can then access them from all of your devices. When you sign up for iCloud, you automatically get 5GB of free storage. Should you need additional storage, fees are as follows: $20 per year for 10GB, $40 per year for 20GB, and $100 per year for 50GB. All the other Apple apps (calendar, mail, and more) are integrated to work seamlessly with iCloud.
  • Google Cloud Connect for Microsoft Office. Google Cloud Connect allows various users to interact using Microsoft Office. This includes simultaneous sharing and editing of Microsoft Word, PowerPoint, and Excel documents. You can also save secure copies of each document. The flexible plan, which you can terminate at any time, is priced at $5 per user account per month, while the annual plan is priced at $50 per user account per year.
  • IBM SmartCloud. IBM SmartCloud provides numerous services for IT companies, such as developing applications in the cloud or using the cloud as a backup for your company files. Use the price estimator to estimate the cost for your particular needs you need to select the software, size, and times that you want to use, plus any additional requirements your company might have. A 12-month commitment, for example, is priced at $1,300 per month for each unit.

Choosing the Best Option

Whether you use your devices as an individual or as a company, you can take advantage of cloud computing. Individuals will find Apple s iCloud particularly useful if you are using Apple devices. Small businesses, in turn, can opt to share documents via Google Cloud Connect, Google Docs, or Dropbox. IT and application development teams should opt for more complex services, such as those provided by IBM SmartCloud.

Final Word

Cloud computing is a relatively new technology that will only become more widespread. It offers many advantages that could immediately benefit you and your business be aware, however, that initial developments come with frequent drawbacks. If you wait a while, the service will likely develop more fully as problems are ironed out. Plus, cost will go down as more people adopt the technology, which is great news for any frugal-minded businessperson.

Cloud Computing Concerns – How Cloud Computing Works #how #the #cloud


How Cloud Computing Works

Perhaps the biggest concerns about cloud computing are security and privacy. The idea of handing over important data to another company worries some people. Corporate executives might hesitate to take advantage of a cloud computing system because they can’t keep their company’s information under lock and key.

The counterargument to this position is that the companies offering cloud computing services live and die by their reputations. It benefits these companies to have reliable security measures in place. Otherwise, the service would lose all its clients. It’s in their interest to employ the most advanced techniques to protect their clients’ data.

Privacy is another matter. If a client can log in from any location to access data and applications, it’s possible the client’s privacy could be compromised. Cloud computing companies will need to find ways to protect client privacy. One way is to use authentication techniques such as user names and passwords. Another is to employ an authorization format — each user can access only the data and applications relevant to his or her job.

Some questions regarding cloud computing are more philosophical. Does the user or company subscribing to the cloud computing service own the data? Does the cloud computing system, which provides the actual storage space, own it? Is it possible for a cloud computing company to deny a client access to that client’s data? Several companies, law firms and universities are debating these and other questions about the nature of cloud computing.

How will cloud computing affect other industries? There’s a growing concern in the IT industry about how cloud computing could impact the business of computer maintenance and repair. If companies switch to using streamlined computer systems, they’ll have fewer IT needs. Some industry experts believe that the need for IT jobs will migrate to the back end of the cloud computing system.

Another area of research in the computer science community is autonomic computing. An autonomic computing system is self-managing, which means the system monitors itself and takes measures to prevent or repair problems. Currently, autonomic computing is mostly theoretical. But, if autonomic computing becomes a reality, it could eliminate the need for many IT maintenance jobs.

To learn more about cloud computing and other related topics, see the links on the next page.

Private Eyes Are Watching You

There are a few standard hacker tricks that could cause cloud computing companies major headaches. One of those is called key logging. A key logging program records keystrokes. If a hacker manages successfully to load a key logging program on a victim’s computer, he or she can study the keystrokes to discover user names and passwords. Of course, if the user’s computer is just a streamlined terminal, it might be impossible to install the program in the first place.

Two cloud database environment models exist: traditional and database as a service (DBaaS).

In a traditional cloud model, a database runs on an IT department’s infrastructure via a virtual machine. Tasks of database oversight and management fall upon IT staffers of the organization.

What is Database as a Service?

By comparison, the DBaaS model is a fee-based subscription service in which the database runs on the service provider’s physical infrastructure. Different service levels are usually available. In a classic DBaaS arrangement, the provider maintains the physical infrastructure and database, leaving the customer to manage the database’s contents and operation.

Alternatively, a customer can set up a managed hosting arrangement, in which the provider handles database maintenance and management. This latter option may be especially attractive to small businesses that have database needs, but lack the adequate IT expertise.

Cloud database benefits

Compared with operating a traditional database on an on-site physical server and storage architecture, a cloud database offers the following distinct advantages:

  • Elimination of physical infrastructure. In a cloud database environment, the cloud computing provider of servers, storage and other infrastructure is responsible for maintenance and availability. The organization that owns and operates the database is only responsible for supporting and maintaining the database software and its contents. In a DBaaS environment, the service provider is responsible for maintaining and operating the database software, leaving the DBaaS users responsible only for their own data.
  • Cost savings. Through the elimination of a physical infrastructure owned and operated by an IT department, significant savings can be achieved from reduced capital expenditures, less staff, decreased electrical and HVAC operating costs, and a smaller amount of needed physical space.

DBaaS benefits

In addition to the benefits of employing a cloud database environment model, contracting with a DBaaS provider offers additional benefits:

  • Instantaneous scalability. Should added database capacity be necessitated by seasonal business peaks or unexpected spikes in demand, a DBaaS provider can quickly offer additional fee-based capacity, throughput and access bandwidth via its own infrastructure. A database operating in a traditional, on-site infrastructure would likely need to wait weeks or months for the procurement and installation of additional server, storage or communications resources.
  • Performance guarantees. Through a service level agreement (SLA). a DBaaS provider may be obligated to provide guarantees that typically quantify minimum uptime availability and transaction response times. An SLA specifies monetary and legal remedies if these performance thresholds are not met.
  • Specialized expertise. In a corporate IT environment, except for the largest multinational enterprises, finding world-class database experts may be difficult, and keeping them on staff may be cost prohibitive. In a DBaaS environment, the provider may serve thousands of customers; thus, finding, affording and keeping world-class talent is less of a challenge.
  • Latest technology. To remain competitive, DBaaS providers work hard to ensure that all database software, server operating systems and other aspects of the overall infrastructure are kept up to date with security and feature updates regularly issued by software vendors.
  • Failover support. For a provider of database services to meet performance and availability guarantees, it is incumbent on that provider to ensure uninterrupted operation should the primary data center fail for any reason. Failover support typically encompasses the operation of multiple mirror image server and data storage facilities. Handled properly, failover to a backup data center should be imperceptible to any customer of that service.
  • Declining pricing. With advances in technology and an intensely competitive marketplace among major service providers, pricing for a wide range of cloud-computing services undergoes continual recalibration. Declining prices are a major impetus for migrating on-site databases and other IT infrastructure to the cloud.

Cloud database architecture

Cloud databases, like their traditional ancestors, can be divided into two broad categories: relational and nonrelational.

A relational database. typically written in structured query language (SQL). is composed of a set of interrelated tables that are organized into rows and columns. The relationship among tables and columns (fields) is specified in a schema. SQL databases, by design, rely on data that is highly consistent in its format, such as banking transactions or a telephone directory. Popular choices include MySQL. Oracle. IBM DB2 and Microsoft SQL Server .

Nonrelational databases, sometimes called NoSQL. do not employ a table model. Instead, they store content, regardless of its structure, as a single document. This technology is well-suited for unstructured data, such as social media content, photos and videos.

Migrating legacy databases to the cloud

An on-premises database can migrate to a cloud implementation. Numerous reasons exist for doing this, including the following:

  • Allows IT to retire on-premises physical server and storage infrastructure;
  • Fills the talent gap when IT lacks adequate in-house database expertise;
  • Improves processing efficiency, especially when applications and analytics that access the data also reside in the cloud; and
  • Achieves cost savings through several means, including:
    • Reduction of in-house IT staff;
    • Continually declining cloud service pricing; and
    • Paying for only the resources actually consumed, known as pay-as-you-go pricing.

Relocating a database to the cloud can be an effective way to further enable business application performance as part of a wider software-as-a-service deployment. Doing so simplifies the processes required to make information available through internet-based connections. Storage consolidation can also be a benefit of moving a company’s databases to the cloud. Databases in multiple departments of a large company, for example, can be combined in the cloud into a single hosted database management system .

How does a cloud database work?

From a structural and design perspective, a cloud database is no different than one that operates on a business’s own on-premises servers. The key difference lies in where it resides.

Where an on-premises database is connected to local users through a corporation’s internal local area network (LAN). a cloud database resides on servers and storage furnished by a cloud or DBaaS provider, and it is accessed solely via the internet. To a software application, for example, a SQL database residing on-premises or in the cloud should appear identical.

Accessed either through direct queries (such as SQL statements) or via API calls, the database’s behavior should be the same. However, it may be possible to discern small differences in response time. An on-premises database, accessed via a LAN. is likely to provide slightly faster response than a cloud-based database, which requires a round trip on the internet for each interaction with the database. In practice, however, the differences are likely to be small.

A history of cloud computing

lebigmac – 24 Nov 2015 5:56 PM

Cloud computing is just another step in the history of communication or – to be more specific – language. Similarly, mathematics is a language. Cloud computing is a huge step. It saves a lot of time, if we ignore the fact that have to earn money working at least dozens of hours a week first, in order to buy equipment required to use cloud computing. Apparently, the better quality of the equipment is, the higher the price gets. The higher the price gets, the longer earning that particular amount of money takes. Honestly, I would be devastated, if I lost mobile access to my professional, academic and personal resources. I am addicted, but cloud computing is also a history of knowledge as commodity. Why does one still have to pay for knowledge? Are there any logical arguments in favor of maintaining status quo? What can we – as humanity – achieve by letting everyone free access to all achievements of human thinking? That was a long digression.

ACM Computing Surveys

Wei Huang, Afshar Ganjali, Beom Heyn Kim, Sukwon Oh, and David Lie

The public Infrastructure-as-a-Service (IaaS) cloud industry has reached a critical mass in the past few years, with many cloud service providers fielding competing services. Despite the competition, some of the security mechanisms offered by the services to be similar, indicating that the cloud industry has established a number of “best-practices,” while other security mechanisms vary widely, indicating that there is also still room for innovation and experimentation. This papers investigates these differences and possible underlying reasons for it. It also contrasts the security mechanisms offered by public IaaS cloud offerings with security mechanisms proposed by academia over the same period.

This paper presents ARGOS, the first system that can automatically uncover the semantics of kernel objects directly from a kernel binary. Based on the principle of data use reveals data semantics, it starts from the execution of system calls (i.e. the user level application interface) and exported kernel APIs (i.e. the kernel module development interface), and automatically tracks how an instruction accesses the kernel object and assigns a bit-vector for each observed kernel object. This bit-vector encodes which system call accesses the object and how the object is accessed (e.g. read, write, create, destroy), from which we derive the meaning of the kernel object based on a set of rules developed according to the general understanding of OS kernels.

Deevi Radha Rani and G. Geethakumari

Cloud computing has recently emerged as a technology to allow users to access infrastructure, storage, software and deployment environment based on a pay-for-what-they-use model. Traditional digital forensics cannot handle the dynamic and multi-tenant nature of the cloud environment as it has to address various technical, legal, and organizational challenges typical to the cloud systems. The dynamic nature of cloud computing allows abundant opportunities to enable digital investigations in the cloud environment. This paper addresses the challenges of digital forensics in the cloud environment and existing solutions to ease some of the challenges. We propose an efficient approach to forensic investigation in cloud using Virtual Machine (VM) snapshots.

Big data opens the era of the fourth paradigm for science discovery through data-driven computing. This new paradigm applies to the design of the future Internet, which currently faces issues in supporting new applications, efficient resource use, and continuous evolvement. In this article, the authors discuss several technological transformations in network architecture, services, and applications, and point out the grand opportunities for designing future Internet architectures, communication models, and resource management mechanisms enabled by the availability of massive network data. In particular, the authors envision in the future Internet: computational complexity replacing state complexity in the control plane; data intelligence enabling user choices and rewards innovations; and correlations from data analytics to help solve inherently hard optimization problems. Finally, the authors identify the key challenges in data-driven Internet design and outline future research directions.
