I have a SQL 2012 R2 HA configured in Azure Iaas VMs, using Availability groups. it has 2 SQL nodes & 1 Listener server (in ILB) under same cloud service. Currently I have only one SQL named instance.
There is a customer requirement that, they wanted multiple SQL named instances in those two SQL nodes, and they need to be in Availability groups.
It is already known that 'Only one availability group listener is supported per cloud service' . Now If I create new named instance & create a new Availability group - how to attach the listener there ?
If Azure doesn't support multiple listeners per cloud service - how to deploy this kind of requirement & what are best possible options ? is there any roadmap to support this ?
if Client wants to stick to the options of multiple named instances on these nodes (like on-premise) - what is best option here ? Deploying them on different set of servers will increase the cost.
Thanks for your suggestion here.
