Failover Cluster - Network Traffic

Question

Hi,

I'm currently playing with Windows Failover Cluster as I want to try and get an app highly avilable for when we move to the cloud (IaaS).

The app has various components such as MSMQ, SQL, Windows services. I believe I can get them all supported and running in harmony. But also the server receives traffic externally and from other internal servers.

I created a ILB with a floating IP and used the Cluster Core IP using HA Ports using probe 59999. I did some basic testing as Im still setting up the other components such as SQL MSMQ etc but I was able to RDP to each box when failing the core over. I thought great, that's the network side done....

However, when I was doing some research, some MVP articles suggested the Cluster Core IP cannot be used for network traffic and that it can't be pinged, resolved etc.

This got me conerned that I may not be configuring network traffic correctly and wondering whats best practise to send traffic to the active node?

Ideally, I'd like all cluster roles on each node and send the traffic respectfully. I can ping and resolve the Core IP.

I'm running Windows Service 2019 & SQL Server 2019 CU2.

Many Thanks,

Brad
