Thus far, USi is offering only virtualized servers running VMware, but according to Christina Schriver, director of advanced engineering for USi, the company will offer Sun Microsystems Solaris Containers and Citrix Systems Xen products this year. Why the expansion? Because it's what customers clamor for.
"We're not getting requests from customers for a particular virtualization platform," Schriver said, explaining that customers don't even see the virtualization layer when hosting their apps with USi. They just see applications running as they should. "But we are getting requests from clients that can best be supported by other [virtualization] vendors."
Some of USi's customers, for example, have asked USi to host Solaris running on Sparc processors, whereas VMware can handle Solaris on only x86 processors from Advanced Micro Devices Inc. (AMD) and Intel Corp.. Schriver explained that in many cases, customers want these options because they already have applications running on Solaris and Sparc and don't want to port them to x86 Solaris or another operating system.
That is what I see from this post:
