"Services and Applications" in Failover Cluster Manager?

Hello,

I was hoping that someone could shed some light on this for me - what exactly is the function of the "services and applications" piece in failover cluster manager (server 2008)?  

For instance I have a cluster named "CLU30" comprised of two nodes, "APP60" and "APP61" which are active/passive.  APP60 has two services/applications running on it named "APP30A" and "APP30B" each of those services has several cluster resources running within each.  What are the purposes of these services/applications?  Is it just to further compartmentalize resources on a cluster node?

Your help is greatly appreciated.

Thanks!

No. It will not Isolate resources on a cluster node. "services & application " In cluster node means High availability  for specified service & application.

Example: If any service fails to respond or stopped then it will failover those service on failover cluster node.

In your case if APP30A & APP30B service/application fails then it will failover the same application on another cluster node "APP61".
