SQL Server AlwaysOn Cluster

by Microsoft
Automates the deployment of a SQL Server AlwaysOn Availability Group for high availability of SQL Server. It provisions 2 SQL Server replicas (primary and secondary) and 1 witness file share in a Windows Cluster. It also provisions 2 Domain Controller replicas (primary and secondary). In addition, it configures an Availability Group Internal Listener for clients to connect to the primary SQL Server replica. The diagram below shows the deployment according to the default settings of this feature. The deployment will look slightly different depending on the settings specified by the user.
This template deploys an AlwaysOn Availability Group such that after deployment is complete, the user has a fully available AG. The template implements performance, security, and availability best practices.
