Virtual Desktop Infrastructure Vs. Virtual Server in the cloud

Virtual Desktop Infrastructure (VDI) has become the latest buzzword in the cloud computing arena. VDI is very similar to Virtual Server (referred to as SBC - Server Based Computing). Both offer virtualization and both holding the virtual environment on a centralized server. This is where the similarities end. VDI provides a full desktop experience while SBC offers terminal service based access to a centralized/shared operating environment. There are pros and cons to each: VDI Pros: 1. Offers a full desktop experience to the user 2. Actual desktop including the OS are available to the user Cons: 1. There is one copy of the desktop/OS for each user 2. There are potentially gigabytes of storage (and associated CPU) required to store each virtual user desktop SBC Pros 1. Less server storage, CPU and RAM required 2. Shared environment for users so easy to provision, management, monitor, and deploy applications Cons 1. User does not get full desktop experience 2. May have to create a portal or mashup so users can see all of their cloud applications in a centralized location There is no right or wrong answer as to what is best for you. Most companies that offer SBC also offer VDI (Oracle, Citrix, VMWare, etc.).

Oracle's Sun Blade modular systems: Can they give VBlock a run for their money?

Check out these new hardware and software integrated solutions from Oracle Sun (they are not Exa* machines): http://www.oracle.com/us/products/servers-storage/servers/blades/index.html They offer a number of solutions not offered by VBlock: Oracle DB, Oracle WebLogic, OS and end to end management. Be interesting to see how much adoption these machines get given the long time VBlock has been around and the Exa* focused strategy at Oracle.
