This is going to be a multi-part post, based on a very recent deployment.
I had to urgently build an AlwaysOn Availability Group and Listener in Azure on SQL Server 2014. The only issue was, I have limited Azure and SQL knowledge. I can maintain and install, and create a few scripts here and there. But not enough to be called a DBA or Cloud Boff. However, I decided this would be an awesome thing to learn how to do. So, during the course of man flu, about 40 hours of crunch time, I can now install, configure and maintain a SQL AlwaysON AG with Listener on Azure.
So, lets get cracking.
- 1x Domain Controller
- 1x Service account for the SQL Server Service and for the SQL Server Agent Service
- 1x Delegated permissions on AD for the cluster to create computer objects.
- 1x Load balancer (on Azure)
- 2x Windows Servers installed with a minimum of SQL 2012 installed
- Shared location on each node (this will be used for adding DBs to the using a “Full” model)
Some of these pre-requisites are listed in this post – so don’t worry if you don’t know how to do certain things.

Today I was investigating upgrading an application we use for email signature management called Symprex. I want to upgrade it using SCCM and realised that internally we didn’t have any “How-To” documentation on deploying an application from start to finish, so what better way to add a post to my blog and some internal documentation.
So, what is supersedence exactly?
Microsoft TechNet gives us a pretty good explanation:
“Application management in Microsoft System Centre 2012 Configuration Manager allows you to upgrade or replace existing applications by using a supersedence relationship. When you supersede an application, you can specify a new deployment type to replace the deployment type of the superseded application and also configure whether to upgrade or uninstall the superseded application before the superseding application is installed.
When you supersede an application, this applies to all future deployments and Application Catalog requests. This will not affect the existing installations of the application.”
