RDS High Availability Connection Broker - When does it actually work?

Question

I have spent much time trying to get Connection Broker HA working. I'm using it on Server 2022 in-house.

I have the HA Cluster setup (DNS Round Robin) and it all shows as it is setup.

When I go the the web interface and the first collection broker (one i initially created) is on, apps work.

If I shut down the first collection broker then the web interface no longer responds. I can't open apps.

So please please please please , because I can't find an answer ANYWHERE!!!!

How does HA actually supposed to work? What's HA about not being able to shut down a box? WHY WHY WHY?

:)

Hello there,

RDS Connection Broker provides high availability in the Active/Active mode. In this mode, all RDCB servers are active and can process incoming connections. It allows providing high RDCB availability and scalability in large Remote Desktop environments.

High availability is established by duplicating each of the roles services on a second machines. In Azure, you can receive a guaranteed uptime by placing the set of the two virtual machines (hosting the same role) in an availability sets.

Along with availability sets, you can now leverage the power of Azure SQL Database and its Azure-backed SLA to ensure that you always have connection information and can redirect users to their desktops and applications.

Hope this resolves your Query !!
