 [Proximity placement groups](../virtual-machines/windows/proximity-placement-groups-portal.md) are a logical grouping capability in Azure Virtual Machines. You can use them to decrease the inter-VM network latency associated with your applications. 
 
-When VMs are deployed within the same proximity placement group, they're physically located as close as possible to each other. Proximity placement groups are useful to address the requirements of latency-sensitive workloads.

 ## Considerations
 
-- The best effort will be to fail over and fail back the virtual machines into a proximity placement group. If there is am OverconstrainedAllocationRequest error due to which we are unable to bring up the VMs inside a proximity placement group, the failover and failback will still execute, but VMs will be created outside the proximity placement group.
-- If an availability set is pinned to a proximity placement group and VMs in the availability set have an allocation constraint during failback or failover, the VMs will be created outside both the availability set and the proximity placement group.

 - Site Recovery for proximity placement groups is not supported for unmanaged disks.
 
 > [!NOTE]
 > Azure Site Recovery does not support failback from managed disks for scenarios of moving from Hyper-V to Azure. Failback from proximity placement groups in Azure to Hyper-V is not supported.
