This blog post describes how to set up a Couchbase Cluster using Azure Resource Manager (ARM) templates. To do this, you need an Azure Subscription, Azure CLI installed on your system, and a Github Account for optional experimentation with ARM templates. The cluster size is configurable but starts with a three-node cluster setup with replication to one node. You can deploy the template using Azure Portal, Azure PowerShell, or Azure CLI. The template uses variables and parameters to configure resources such as virtual networks, network interfaces, and virtual machines. It also includes scripts for installing Couchbase Server on each VM and setting up the cluster. The ARM template is publicly available on GitHub, and you can use it to deploy a Couchbase Cluster in Microsoft Azure.
