Windows Server 2012 R2

Windows Server 2012 R2 is the successor to Windows Server 2012, Microsoft’s enterprise server operating system. Developed under the Windows Server Blue codename, Windows Server 2012 R2 is expected to make its official debut in late 2013, with pricing to be announced at a later time.

Among its many improvements, Windows Server 2012 R2 will include an enhanced Hyper-V hypervisor (Hyper-V 2012 R2) that is expected to provide the ability to compress virtual machines (VMs) during live migrations, automatic reallocation of memory between VMs running Linux as a guest on Hyper-V hosts; remote direct memory access (RDMA) support during live migrations, VM live cloning, and support for shared VHDX files.

Windows Server 2012 R2 will also feature enhanced integration and interoperability with Microsoft’s Windows Azure cloud platform and the company’s cloud-based version of Microsoft Office, Office 365.

Windows Server 2012 R2 was announced on June 3rd, 2013, and a preview release became available for download later that month, on June 24th. When officially released, Windows Server 2012 R2 will be available in Standard, Datacenter and Essentials editions.
