PSC within VCF

Jump to solution

Hi All

I have notice that the PSC is deployed with two instances within the bring up and configured to replicate with each other and as other WLD are brought they added to this. The question I have is that based on the VVD there is a post deploy configuration to put a load balancer in front of the PSC but don't see any reference to this as a requirement within VCF.

Is this something that still needs to be done or is it a case of repointing the vCenters to the available PSC in the event of a failure?

If a load balancer has to be introduced will SDDC manager still support the lifecycle operations for the virtual infrastructure layer.

Thanks in advance

There are some differences in the architecture for VMware Cloud Foundation and the VMware Validated Designs, this is one of those deltas.

No changes are required to the deployment of the Platform Services Controllers in VMware Cloud Foundation, these should remain as deployed. Any post-deployment introduction of an load-balancer for the services, endpoint repointing, and the like would be unknown to the SDDC Manager inventory and workflows and will result in issues with day-two operations like WLD creation and lifecycle management.

You can expect to see someconvergence in the architecture for both in due course since deprecation of external Platform Services Controllers was announced for future vSphere releases.

Even I am wondering about the same.

Curious about load balancer part of your question (since it will be deployed outside of SDDC Manager).

Thank you Ryan for the update. In the event of a failure do we then operationally just do a repoint to the surviving node and then restore from a backup of the psc?

Yes, that is correct. Smiley Happy

When adding new workload domains in VCF I know it will add an additional vCenter in linked mode and using the original SSO from bring up. Question I have is, will this deploy an additional PSC along with that vCenter? And where will it reside from a placement perspective, Management Cluster or WLD cluster?

It will not deploy additional PSC. The newly deployed vCenter will be in same SSO domain as mgmt cluster and all the mgmt components (vcenter,nsx,controllers etc) of workload domain are deployed in Mgmt cluster.
