MSCS H/A enqueue, replication and message servers services

Hi,

I'm looking at the documentation about "Installation of multiple SAP Systems in MSCS: MSSQL Server" but I have a few questions about the SCS and ASCS process.

Are the process setup as generic cluster service? Or are they SAP provided cluster services?

What monitoring is done with the the enqueue, replication and message server services in the cluster?
