This article configures SQL Server Always On Availability Groups on the domain independent Windows Failover Clusters. In the previous article, Deploy a domain-independent Windows Failover Cluster for SQL Server Always On Availability Groups, we learned the new capability in Windows Server 2016 to configure a domain-independent Windows failover cluster.
This article continues from the series on SQL Server Always On Availability Group. This is the 11th article in this series.
In the previous article, Deploy a domain-independent Windows Failover Cluster for SQL Server Always On Availability Groups, we learned the new capability in Windows Server 2016 to configure a domain-independent Windows failover cluster. We did the following steps in the previous article.
In this article, we will configure an Availability Group on the domain-independent cluster.
First, you should install the SQL Server database engine on all nodes participating in the failover cluster. I do not cover all steps in SQL Server 2019 installation in this article, and you can explore the previous article in the series for detailed instructions.
As you know, we do not have an active directory configured for both nodes in my failover cluster. You should use the built-in service accounts(NT Service). As per best practice, you should grant volume maintenance task privilege for the SQL Server Database engine service, as shown below.
Open the SQL Server Configuration Manager and put a tick on the Enable Always On Availability Group. You can see the name of the domain-independent failover cluster on this page. You must restart SQL Services to make the changes effective.
Similarly, enable the Always-on availability groups on the SQLAG2 node and restart SQL Services.
A domain-independent uses the database master key for SQL Server Always On Availability Group. You require a password to encrypt the database master key.

We configure the SQLAG1 as the primary replica for this article.
In this step, we create a certificate to secure the availability group endpoint in SQL Server Always On. This certificate is also useful to secure the inbound traffic on the secondary AG. SQL Server uses these certificates for authentication purposes as well in a domain-independent cluster.
Execute this script on the primary replica SQLAG1.
We need to take a backup of the certificate created in step 4. This certificate is required later in the secondary replica user authentication.
In this step, we create an endpoint on the primary replica SQLAG1 with the following information.
SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.
This article gives an overview of SQL Server Always On Availability Group features. We configured the SQL Server Always On Availability Group from the beginning of building virtual machines.
This article gives an overview of Configuring Managed Service Accounts for SQL Server Always On Availability Groups.
In this article, we will discuss configuring SQL Server Always On Availability Groups and perform failover validations. You should go through the following articles and build the infrastructure before proceeding with this article.
SQL Server 2016 provides a new feature Distributed Availability Group for disaster recovery purposes. It is a particular type of availability group that helps access the multiple failover clusters. In this article’s series, we configured a traditional Always On group. It has the following requirements.
