Microsoft announced the second release of its Windows Server 2008 operating system at its Professional Developer Conference in Los Angeles this week.
The updated OS includes a range of new features, including support for Web applications, better virtualization and improved scalability and reliability.
Virtualization will be a key feature of the new OS, with Microsoft announcing that Server 2008 R2 will include "Live Migration", a feature which allows users to move a virtual machine between two computers running Microsoft's hypervisor, Hyper-V. Microsoft said that the new version of Hyper-V shipped with Server 2008 R2 will include better management features.
Microsoft also said that Server 2008 R2 has many features specifically designed to work with client computers running the upcoming Windows 7, including better usability and accessibility.
According to the reviewer's guide published on Microsoft's Web site, Server 2008 R2 will be available exclusively as a 64-bit OS.
