Configuring Advanced Windows Server 2012 R2 Services: Virtual Machine and Site Resilience

Site resilience enables you to ensure that your organization’s access to important virtual servers continue in the event that a critical site goes offline unexpectedly. As virtual servers are data, moving a virtual machine from an offline site to one that is accessible is a lot simpler than putting hardware on a truck and driving it to a new datacenter. You can move servers between sites by transferring the data that constitutes the servers between sites. This lesson explains different techniques to move virtual machines from one Hyper-V server to another, whether it is a node in the same cluster, another Hyper-V server in the same site, or to a Hyper-V server hosting a replica in another country or on another continent.

Lessons in this chapter:

• Lesson 1: Virtual machine movement
• Lesson 2: Site-level fault tolerance

Before you begin

Unlike other practices in this book, moving virtual machines between computers running Windows Server 2012 R2 requires more than one host computer running Windows Server 2012 R2. The instructions at the beginning of the practice exercise describe how you can build servers that make it possible for you to configure virtual machine movement and replication.
