Bandwidth is not doubt an important components to have a successful cloud architecture. Typically co-locs have a very high bandwidth pipe. The bottleneck is usually at the last mile to either office, home or at the RF link to the mobile device. Yet, if the community is not convinced that their data is secured, I don't believe just by delivering convenience alone will be able to get cloud based services popular. I believe technologies are growing to address both security and bandwidth at this point.
The security of the cloud is one issue, another one is having a very reliable high bandwidth network capable of sending and receiving large amounts of data to and from the cloud. It does no good to have vast amounts of data stored in "clouds" if you cannot access it quickly whenever it is needed. My personal experience both at my workplace and my home is that the networks are already straining now to do the job. How will they handle the additional burdens of cloud computing? I think we are going to need a lot more optical fiber in the ground and the whole infrastructure that goes with it.
chanj, Thank you for your question. Data at rest security is implemented across the board. Since important data is stored on the servers and not on the clients, files are not stored or transmitted unless policy permits it to a device. If a device is lost, destroyed, or stolen, the data sits on the server and is not affected. We implement policy-based access control regarding printing, usage, and device access. Additional policies can also be used to restrict sharing, printing, clipboard sharing, and even local USB device access. VERDE follows Authentication, Authorization, and Accounting security protocols. In addition, VERDE has protocol encryption (SSL) to make sure that granular items such as keystrokes and pixels are secured. This means that even the bits and pieces that hackers could use to put together data are safely encrypted.
I'm particularly excited to hear IDC's report because, my company, Virtual Bridges's VDI Gen2 and LEAF solutions contribute to the need for energy, cost, management, and reliability needs required for virtualization in the cloud. VERDE also takes advantage of cluster server fail-over in a way that is simple for IT administrators to manage. VDI Gen2 also allows for secure deployments in both private and public clouds. Virtualization solutions across the board will help streamline and reduce the headaches that current IT managers are facing.
Though there is an initial apprehension about the security of data on the Cloud, this will soon melt away and the shift towards using public Cloud will start. The advantages of lower total cost of ownership of the Cloud based services compared to the Captive IT infrastructure will weigh in when the future IT investment decisions are made.
