Azure Site Recovery is a disaster recovery solution provided by Microsoft Azure. It enables businesses to keep their critical applications and workloads running during planned or unplanned downtime by orchestrating replication, failover, and recovery of virtual machines and physical servers.
Here are some examples of how Azure Site Recovery can be used:
- Disaster recovery: Azure Site Recovery can be used to protect critical applications and workloads from unexpected failures or disasters. In case of an outage or disaster, Azure Site Recovery can help in ensuring a quick and smooth failover to the replicated environment.
- Migration: Azure Site Recovery can be used to migrate virtual machines and physical servers from on-premises to Azure or from one Azure region to another. This can help in reducing the complexity and cost of migration.
- Testing: Azure Site Recovery can be used to test the disaster recovery plan of critical applications and workloads without disrupting the production environment. This can help in identifying and addressing any issues before an actual disaster or outage occurs.
- High availability: Azure Site Recovery can be used to provide high availability for critical applications and workloads by replicating them to a secondary location. This can help in minimizing downtime and improving application availability.
- Dev/test environment: Azure Site Recovery can be used to create dev/test environments in Azure by replicating production workloads to a separate environment. This can help in reducing the cost and complexity of creating dev/test environments.
Azure Site Recovery can help in ensuring business continuity and minimizing downtime during unexpected failures or disasters. It is a reliable and scalable solution that can be tailored to meet the specific needs of different businesses.
Here’s how it works:
- Replication: Azure Site Recovery replicates virtual machines and physical servers from a primary site to a secondary site. The replication can be continuous or scheduled, depending on the specific needs of the business.
- Orchestration: Once the replication is complete, Azure Site Recovery orchestrates the failover and recovery of the virtual machines and physical servers in case of an outage or disaster. The orchestration is done based on predefined recovery plans, which are created and customized by the business.
- Failover: In case of an outage or disaster, the failover process is triggered, and the virtual machines and physical servers are brought up in the secondary site. This helps in ensuring continuity of critical applications and workloads.
- Failback: Once the primary site is back up and running, Azure Site Recovery helps in failing back the virtual machines and physical servers to the primary site. This ensures that the replication is re-established and the business is back to its normal state.
Here are some examples of how Azure Site Recovery works:
- A business that runs critical applications and workloads in an on-premises data center can use Azure Site Recovery to replicate these to Azure. In case of an outage or disaster, the business can failover to the replicated environment in Azure and ensure continuity of operations.
- A business that has critical applications and workloads running in Azure can use Azure Site Recovery to replicate these to another Azure region. In case of an outage or disaster in one region, the business can failover to the replicated environment in the other region and ensure continuity of operations.
- A business that wants to migrate its on-premises data center to Azure can use Azure Site Recovery to replicate its virtual machines and physical servers to Azure. Once the replication is complete, the business can failover to the replicated environment in Azure and complete the migration process.
