Azure Site Recovery (ASR) now supports proximity placement groups (PPGs) from the Azure portal. Recall that previously, ASR only supported Proximity placement groups when configured via PowerShell. The new functionality in the portal is a lot more seamless, and I highly recommend it for replicating for failover and failback to a secondary region, any workloads that are configured within proximity placement groups. Recall that proximity placement groups is a construct that enables you to logically group your application components together to avoid network latency between the various tiers of your application. The use case for this in the context of site recovery is that while PPGs provide optimal network latency for your application, you also want to ensure that in … Read More

The class instances for certain classes will return the parent class as well as associated classes in the following format: [Parent Class Name].attribute.
