The document discusses disaster recovery frameworks in cloud computing. It notes that virtualization allows entire virtual servers to be backed up to a second data center, making recovery of operating systems, applications, and data hardware independent. This creates more cost effective disaster recovery options than traditional methods. Specifically, the cloud shifts the disaster recovery cost curve by enabling lower cost options like online backup that can achieve faster recovery times than traditional warm or cold site options.

4. What Changes in the Cloud?
VIRTUALIZATION & HARDWARE INDEPENDENCE
• Once you virtualize into the cloud …
• Entire virtual server can be backed up to a 2nd data center
– Hardware independent
– OS, apps & patches already in place
• Creates more cost effective D/R options
