Exploring Azure Site Recovery
The last topic of this chapter is a service called Azure Site Recovery. It’s part of Azure Recovery Services, which we already discussed when talking about Azure Backup for our workloads. While backups allow us to provide improved security for VMs and databases, Azure Site Recovery is meant to grant us the possibility to provide BC in case of unexpected failures. We’ll discuss various options when it comes to recovering from outages and prerequisites to achieve continuity.

There are three different possibilities when thinking about replication:
