Azure Site Recovery: Ensuring Business Continuity

Any downtime can lead to significant financial losses and damage to the organisation’s reputation. This is where Azure Site Recovery (ASR) comes into play.


In the digital age, business continuity is heavily dependent on the uninterrupted functioning of IT infrastructure. Azure Site Recovery (ASR), a service offered by Microsoft as part of its Azure cloud platform, plays a crucial role in ensuring that your business applications continue to run during both planned and unplanned outages.

How Azure Site Recovery Works

ASR works by replicating workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. When an outage occurs at your primary site, you fail over to the secondary location, and access the apps from there. Once the primary location is up and running again, you can fail back to it.


Implementing Azure Site Recovery involves a series of steps:

  1. Prepare your infrastructure: Identify the resources that you want to protect, prepare the source and target environments, and choose your replication strategy.

  2. Enable replication: Configure the settings and enable replication. ASR will start replicating your data to the target location.

  3. Test failover: Perform a test failover to ensure that everything is working as expected.

  4. Failover and failback: When an outage occurs, you can easily failover to the secondary site. Once the primary site is up and running, you can fail back to it.

For example, if you have an e-commerce application running on a VM in your primary site, you can use ASR to replicate this VM to Azure. In the event of an outage, you can failover to the VM in Azure, ensuring that your e-commerce application remains available to your customers.


Implementing Azure Site Recovery as part of your BCDR strategy ensures that your business applications are always available, thereby minimizing the impact of outages on your business operations. It provides a robust and reliable solution for maintaining business continuity in the face of disruptions.
