UPDATE: I strongly recommend upgrading to the latest version of 9.1. VMware Cloud Foundation (VCF) 9.0.x general support ends on September 17, 2027.
Smaller environments running VCF 9 might have a subset of the VCF components/appliances deployed. This minimizes the virtual infrastructure management footprint and resource consumption. For example, a three-host environment might have VCF Operations 9 + vCenter 9 + ESX 9. The downside to these types of deployments is you lose some of the VCF functionality such as fleet management. This begs the question, "How do I update the components I have?" You can upgrade version 9 components such as VCF Operations, vCenter, and ESX similar how you upgraded version 8.
