I generally try to avoid too much marketing stuff but this is a really neat case study that recently came out and I thought you might be interested in seeing it. The overview is below but if you want to jump right in you can access the site here.
Gen, a subsidiary of Q-Comm Corporation, delivers office productivity and line of business applications on a “Software as a Service” basis to small and midsize organizations around the world.
Gen wanted to grow its business and expand its capacity to meet customer needs, but its existing service delivery infrastructure would not scale efficiently.
Gen deployed Microsoft SoftGrid Application Virtualization for Terminal Services and augmented the service delivery environment of Gen with load balancing technologies.
Eliminated the application conflicts that created service delivery inefficiencies
Enabled existing server infrastructure to support more users with greater performance
Effectively converted existing infrastructure into one capable of supporting a nationwide service rollout
HP Reliant servers
