VMware Cloud Foundation 9.1 - private cloud, private AI, enterprise-grade kubernetes

VMware Cloud Foundation 9.1

Our cousins over in VMware announced the most recent version of VMware Cloud Foundation, 9.1, yesterday. We all call this “VCF.” It’s at the center of Broadcom’s strategy to be the private cloud stack for large enterprises. You know: banks, governments, large retailers, manufactures, et. al.

Our layer, the Tanzu Platform, sits a-top VCF like any PaaS would sit a-top IaaS.

Recently, the VCF people have been putting a lot of effort into private cloud AI. You can think of that as “local AI” if you prefer. From the last three surveys they’ve done, you can see a steady interest in running private AI:

Broadcom commissioned surveys from IDC (2024) and Radius Tech (2025, 2026).

Kubernetes, memory, and AI

If you’re a full private cloud stack, there’s a lot going on each release, so here’s three interesting things:

  1. VKS now scales to 500 Kubernetes clusters per Supervisor. That’s a platform-of-platforms number. If you’re running a multi-tenant Kubernetes service, 500 clusters per supervisor is meaningful for compliance boundaries, and AI workload placement. Real enterprise-grade stuff. Also, for some platform-y related things like packaging and deploying containers, managing them, etc. see this post.

  2. Memory tiering and storage dedup go after the DRAM problem head-on. Enhanced NVMe memory tiering keeps hot pages in DRAM and pushes cold pages to NVMe, with vSAN global deduplication and stronger compression behind it. They say this is up to 40% lower TCO.

  3. Native MCP support, with governance, in VCF Private AI Services. VCF 9.1 ships Model Context Protocol support with pre-built, governed connectors to Oracle, Microsoft SQL Server, ServiceNow, GitHub, Slack, Postgres, and the rest. That matters because it’s the difference between “we host an LLM” and “the LLM can actually do work against our internal systems.” There’s also support for Google Docs, metrics, and more.
