Hey there!! Today I’m going to show you how to use Azure Policy to ensure disaster recovery (DR) of your virtual machines (VMs). Azure Policy is a service that lets you create and assign policies to your Azure resources, such as VMs, storage accounts, networks, etc. Policies are rules that define what actions are allowed or denied on your resources. For example, you can use policies to enforce naming conventions, tags, locations, sizes, and more.
One of the benefits of using Azure Policy is that you can ensure DR of your VMs by applying policies that require them to have backup and replication enabled. Backup and replication are essential for DR because they allow you to restore your VMs in case of a failure or disaster. Backup creates a point-in-time snapshot of your VM that you can use to restore it to a previous state. Replication creates a copy of your VM in another region that you can use to failover if your primary region is unavailable.
To use Azure Policy for DR, you need to do the following steps:
- Create a backup policy that defines how often and for how long you want to backup your VMs. You can use the built-in backup policy or create a custom one.
- Create a replication policy that defines which region you want to replicate your VMs to and how often you want to sync them. You can use the built-in replication policy or create a custom one.
- Assign the backup and replication policies to your VMs or to a resource group or subscription that contains them. You can use the Azure portal, PowerShell, CLI, or REST API to do this.
- Monitor and manage your backup and replication policies using the Azure portal, PowerShell, CLI, or REST API. You can view the status of your backups and replications, restore or failover your VMs, modify or delete your policies, and more.
That’s it! You have now used Azure Policy to ensure DR of your VMs. I hope you found this blog post helpful and informative.
Thanks for reading and happy clouding!
