This diagram illustrates the process of the VCF Installer API calling and managing three ESX hosts within a VMware Cloud Foundation environment. It shows the API communicating with the VCF SDDC Manager via REST API calls for host management and secure connection. The ESX hosts, each labeled with individual IP addresses and running ESXi 8.0, undergo different configuration stages such as host validation, networking setup, datastore configuration (including vSAN), installation of ESXi components, and registration with vCenter. Visual elements include interconnected servers, API icons, and flow arrows to depict data and control flows in a technical and futuristic style, using blue and orange highlights to differentiate operational processes.
