vSphere cluster groups are sets of ESXi hosts that have a common compute entity; there are from 2 to 64 hosts per vSphere cluster when vSphere HA and DRS are activated at the cluster level. Resource pools are created under a vSphere cluster instance, and vCenter is able to manage multiple vSphere clusters instances, as there is no hard limit to the number of vSphere clusters. We can create different types of vSphere clusters, such as management clusters, compute clusters, and Edge clusters, since PKS fully leverages the vSphere cluster construct.
The following vSphere clusters are recommended in a typical PKS deployment:
- Management cluster:
- Hosted components: vCenter, NSX manager, and controller VMs
- vSphere HA and DRS enabled
- ESXi hosts need to be NSX prepared, as micro-segmentation is enforced on the hosted VMs
- Compute cluster(s):
- Hosted components: Kubernetes...
