Solution Overview

As an organization you need to adopt a business continuity and disaster recovery (BCDR) strategy that keeps your data safe, and your apps and workloads up and running, when planned and unplanned outages occur Azure Recovery Services contribute to your DR strategy:

• Site Recovery service: Site Recovery helps ensure business continuity by keeping business apps and workloads running during outages. Site Recovery replicates workloads running on physical and/or virtual machines (VMs) from a primary site to a secondary location. When an outage occurs at your primary site, you fail over to secondary location, and access apps from there. After the primary location is running again, you can fail back to it.

Site Recovery can manage replication for:

• Azure VMs replicating between Azure regions.
• On-premises VMs and physical servers replicating to Azure, or to a secondary site.

1. On-premises VM replication: You can replicate on-premises VMs and physical servers to Azure. Replication to Azure eliminates the cost and complexity of maintaining a secondary datacenter.
2. Workload replication: Replicate any workload running on supported Azure VMs, on-premises Hyper-V and VMware VMs, and Windows/Linux physical servers.
3. RTO and RPO targets:Site Recovery provides continuous replication for Azure VMs and VMware VMs, and replication frequency as low as 30 seconds for Hyper-V.
4. Keep apps consistent over failover: You can replicate using recovery points with application-consistent snapshots. These snapshots capture disk data, all data in memory, and all transactions in process.
5. Testing without disruption: You can easily run disaster recovery drills, without affecting ongoing replication.

Customized recovery plans: Using recovery plans, can customize and sequence the failover and recovery of multi-tier applications running on multiple VMs.
