Hello,

We have an existing deployment of SCVMM 2012 R2 with high availability on two nodes Windows Failover Cluster of Windows Server 2012 R2.

Now we are planning for System Center 2012 R2 App Controller. So is it possible that we install App Controller on the same machines which have VMM 2012 R2 management servers already installed?

Are there some limitations/disadvantages of installing App Controller on VMM management servers?

Please advise.

Thank you.

By default VMM uses port 443 for BITS transfers.

If you install App Controller on the VMM Server, then the VMM Server will replace the web site certificate with its own self-signed certificate. This will likely cause users to see an untrusted cert when connecting to App Controller.

There are 2 ways to avoid the conflict over port 443:

1. When installing VMM, select a different port for BITS (this is likely too late for you since you already have VMM installed)
2. Install App Controller on a different port (e.g. 8443) and set up a redirect from port 80 to 8443 (this allows users to type in the server name and be redirected to the secure port. It can be confusing though if they type https://servername since it will land on the BITS port.

In your environment, since you have a clustered VMM I would recommend creating a virtual machine for App Controller. You can then either make it HA by marking the VM as HA, or you can create a second VM and install a second instance of App Controller and place it behind a load balancer. App Controller isn't designed/tested to be HA using a cluster.
