It is like a single point of failure. In an environment, vCenter is deployed as a single instance, which represents a single point of failure. The concern here is that tasks such as provisioning, monitoring, and maintenance may be impacted until the server is restored. This only affects management; users are not impacted. But, again, management capabilities will be impacted. The entire system goes down until recovery is completed. You will not be able to provision new VDI. Also, vCenter requires a lot of additional resources for managing capabilities. It uses a significant amount of CPU, memory, and network bandwidth, which can sometimes slow down. Proper sizing is important for vCenter so that it does not impact end-users. vCentre licensing cost is on the higher side as well.
