Using virtualization in a disaster recovery strategy
This article is part of the Virtual Data Center issue of September 2009, Vol. 14
Server virtualization is rapidly becoming a key part of many organizations' disaster recovery (DR) strategy. This is for good reason, as the properties that make server virtualization so compelling in a consolidation effort also play naturally into streamlining DR as well. That said, the use of server virtualization for DR purposes is not a "slam dunk" by any means. While server virtualization can help, it also poses its own unique set of challenges. In this article, we'll examine some of the benefits as well as some of the drawbacks that come out of using server virtualization as part of a DR plan. Virtual machines (VMs) intrinsically possess two qualities that are quite beneficial to DR: Hardware independence: Virtual machines are naturally isolated from the underlying physical hardware by the very operation of the server virtualization software, granting them hardware independence. Encapsulation: Virtual machines are encapsulated into discrete storage areas. Depending upon the virtualization solution, this encapsulation may ...
Features in this issue
New and emerging virtual networking technologies offer better options for deploying and managing virtual infrastructure networking.
Now server virtualization is used in disaster recovery (DR) settings, and virtualization for DR can be a great fit and a cost reducer.
Lifecycle management in a virtual infrastructure poses a few more challenges than you're used to. Without proper lifecycle management, you could end up with VM sprawl.
