I am looking for information on setting up multiple instances of SQL 2014 on a single server and then adding each of those instances into availability groups. Is this supported? Is this a good idea? Has anyone done it? Are there best practices for this?
Currently I have a test environment with 3 SQL 2014 servers and a domain controller. The 3 SQL servers are in a WSFC and I have an availability group setup for 3 databases. This setup works great. Now to add another level of complexity to this, I would like to install another SQL instance on each of the 3 SQL servers and then build another availability group for this new instance. Is this possible? I have been asked to research this setup so that we could possibly find a way to prevent our SQL sprawl that we are currently experiencing.
Any advice or guidance would be greatly appreciated.
Thanks,
TD
