VMware has announced the deprecation of the external PSC deployment model.
In a future vSphere release (not update release), there will no longer be an option to deploy the external PSC. Going forward the embedded deployment will be the only way to deploy vCenter Server.
This will provide an easier vCenter Server lifecycle which means easier deployments, upgrades, and fewer nodes to manage.
With vSphere 6.5 Update 2 and vSphere 6.7, VMware introduced enhanced linked mode support for embedded PSC deployments. So, customers could now get all of the features and benefits of using external PSCs but without the complexity of extra nodes or load balancers.
Customers who already are using external PSC deployments, a new utility is introduced in vSphere 6.7 Update 1. The converge utility allows customers with an external PSC deployment to migrate to an embedded PSC deployment.
Customers can protect vCenter Server and its embedded PSC using a native availability solution – vCHA (vCenter High Availability) – all without external components or load balancers.
