Clustering Implementations for High
Availability
Hyper-V HA implementations can broadly be categorized into Hyper-V Guest
Clustering and Hyper-V Host Clustering. The differences in the two types are
based on where the clustering service is running and what the clustering
service is managing.
Hyper-V Guest Clustering
In a Guest Cluster implementation, the clustering service runs on the guest
operating system in the virtual machine. This type of clustering provides high
availability for applications that are hosted within the virtual machines.
As illustrated in Figure 2-1 and Figure 2-2 below, Hyper-V Guest Clustering
can be implemented with the VMs either deployed on a single physical server,
or across multiple physical servers.
