As with all systems, deployment isn't the end of a cluster's administrative needs. Once in production, your cluster will need to be kept up-to-date.

Cluster validation
Best Practices Analyzer for Hyper-V
Windows Server Update Services
Cluster-Aware Updating
Monitoring and metering Hyper-V hosts and guests
