Hi,
We have Two Applications servers (APPVM1 and APPVM2) running in an Availability setASet1. The connections to these application servers are directed thourgh a load balancer APPLB.On the other hand, we have two database servers DBVM1 (primary) and DBVM2 (secondary) running in an Availability setASet2. Both the database servers are connected to a Database Load Balancer DBLB.All the connections hit the application server via application load balancer in round robin fashion and further hit the database via database load balancer in round robin fashion.Our requirement is that the connections to the database should go only to DBVM1. (The DBVM1 and DBVM2 are having replication in place). If and only if the DBVM1 goes down the connections should be redirected from the Database load balancer to DBVM2. Few things to note
1. We do not want to expose the VMs to public.
2. Traffic Manager does not meet our requirement.
3. Session Affinity does not completely address the issue.
4. We do not want to create a seperate VM for broker/monitor processes for keeping the VM in ready/busy state under the load balancer.
Let me know if you have any questions or clarifications on my question.
Thanks & Regards
Venu
