Microsoft to acquire maker of virtualization software

Seattle PI | at | by Mike

Microsoft plans to acquire San Jose, Calif.-based Calista Technologies Inc. as part of a larger effort to catch up in a growing area of the corporate technology market.

Calista's specialty is making networks run smoothly for virtualized computer desktops -- situations in which the computing takes place on a remote server, but feels to users as though it is happening on a machine sitting next to their keyboard and screen.

The acquisition is part of a broader attempt by Microsoft to position itself in the market for virtualization, a broad term for a series of technological tricks that let companies use software and hardware in more flexible ways. Other types of virtualization include the ability to run multiple operating systems on a single computer or server.
