What it is
VMware Cloud Foundation, usually shortened to VCF, bundles vSphere, vSAN, NSX and the operations tooling into a single product. SDDC Manager knows the dependencies between those components and applies updates in an order that has been tested.
Run the pieces separately and you maintain a compatibility matrix by hand, and every update becomes its own project.
What it is for
Private cloud in your own datacentre, built from standard blocks with an API in front of them. VCF is aimed at estates large enough that operational effort and standardisation outweigh the price of any single licence.
What changed
Since Broadcom acquired VMware, VCF is the central offering and licensing is a per-core subscription. Moving from older perpetual licences changes the cost. That belongs in the planning before the technical design does.
