vSphere Lifecycle Manager (vLCM) in VMware Cloud Foundation is primarily responsible for updating and managing the lifecycle of ESXi hosts in a standardized manner. It allows administrators to define update baselines and images for the ESXi hosts in workload domains.

vCenter Server and NSX Manager are generally managed by SDDC Manager within VCF, not directly by vLCM.

SDDC Manager itself also has its own update mechanism separate from vLCM.
