Host Clustering • VM’s move from server to server • Zero downtime to move a VM • Works with any application or guest OS Guest Clustering • • Apps move from VM to VM Downtime when moving applications Requires “cluster aware” applications running on Windows Server Requires double the resources – 2 VM’s for single workload
