Overview of Site Protection with Azure IaaS using Azure Site Recovery

Consider the following points when working with VMware Site Recovery or Azure Site recovery for DR planning and implementation.

• When working with either VMware Site Recovery Manager or Azure Site Recovery to provide DR for the AVS private cloud, manual input should be minimized as much as possible by leveraging automated Recovery plans within each of the respective solutions. A recovery plan gathers machines into recovery groups for the purpose of failover and helps to define a systematic recovery process by creating small independent units that can fail over.
• Utilizing the geopolitical region pair as the secondary DR environment is recommended for proximity of regions and cost reductions.
• Keep address spaces completely different (i.e., 192.168.0.0/16 for Region 1 and 10.0.0.0/16 for Region 2) to reduce risk of IP address overlap
• Leverage ExpressRoute Global Reach connectivity between the primary and secondary AVS private clouds. Refer to bandwidth considerations <link to networking CDA bandwidth section> for optimal replication purposes.
