Hello,
My company are looking to implement some new SQL Always On AG's over the course of the next few months, all of the infrastructure will be located in Azure. We would like to create and implement a level of DR into this solution and have as close to 100% uptime as possible from the start, I was wondering what people's thoughts are about this?
Initially we would be looking at a 2 node SQL always on AG, and then scale out to DR. Ideally we would like the DR in another region. We've been toying around with the idea of having potentially a 4 node AG, 2 located in one region and 2 for DR in another region, and setting the DR replicas as asynchronous?
Suggestions?
