Storage Replica & Azure VMs: Hybrid Cloud DR on the Fly

bwdur Hi. The main difference is ASR is VM replication only. Application replication, in industry terms. Storage Replica is agnostic block replication, it doesn't know or care about workload. Whichever one you decide to use comes down to your scenario-specific features. https://docs.microsoft.com/en-us/windows-server/storage/storage-replica/storage-replica-overview

I've talked about this "when to use" at a number of conferences, those decks and videos are available. Here is one example from Ignite 2017, see the 50:10 mark: https://channel9.msdn.com/Events/Ignite/Microsoft-Ignite-Orlando-2017/BRK3325
