VCF 9.1 - Understanding VCF Express Patches

07.08.2026 by William Lam // Leave a Comment

AI has fundamentally changed the software industry through its ability to discover software vulnerabilities at an unprecedented pace. This has driven software vendors to adopt faster release cadences, making more frequent software updates the new industry norm.

VMware Cloud Foundation (VCF) is no exception. With the unified versioning introduced in VCF 9, several release types are available to deliver updates, each serving a specific purpose.

The following diagram summarizes the VCF unified versioning model, showing whether each release type is synchronized across the VCF software stack or delivered independently, along with its installation method.


Rather than bundling security fixes into the next scheduled maintenance release, Express Patches allow them to be delivered as soon as they are available. Unlike upgrades, which must be applied in a specific order, Express Patches can be applied in any order, reducing some of the overhead in rolling out the fixes.

As a result of this faster release cadence, product fixes can also be delivered much sooner, rather than waiting for the next maintenance or minor release.

What Host Lifecycle Operations Are Available after Importing vCenter into VCF 9.x Fleet?

06.24.2026 by William Lam // 3 Comments

VMware Cloud Foundation (VCF) first introduced the Brownfield Import capability in VCF 5.2, making it easy for customers to onboard their existing vSphere environments into a VCF deployment. While the Brownfield Import capability had some limitations in earlier releases, it has seen significant enhancements since VCF 9.0 and now provides a native onboarding experience using either the VCF Installer or as a Day-N operation within VCF Operations.

While some customers may have the opportunity to deploy a brand new VCF 9.1 Fleet as part of a hardware refresh initiative, the vast majority will start by converting an existing vSphere environment into their initial VCF Management Domain and then import their remaining vSphere environments as VCF Workload Domains.

In addition to providing centralized visibility and lifecycle management (patching and upgrades) for imported environments, one of the most common question is around what host lifecycle operations can be performed after an environment has been imported into VCF.

VCF 9.1 - Enabling High Availability for a Small VCF Management Services (VCFMS) Deployment

06.22.2026 by William Lam // 4 Comments

When deploying a new VMware Cloud Foundation (VCF) 9.1 Fleet, users specify either a Simple or High Availability (HA) deployment model along with the desired deployment size: Small, Medium or Large. Unlike components such as NSX Manager, VCF Operations and VCF Automation, where deployment size and availability are configured independently, VCF Management Services (VCFMS) determines its availability model based on the selected deployment size.

  • Simple
    • Small - 1 x Control Plane Node (4 vCPU & 10GB mem) + 3 x Worker Node (12 vCPU & 24GB mem)
  • High Availability
    • Medium - 3 x Control Plane Node (4 vCPU & 10GB mem) + 3 x Worker Node (24 vCPU & 48GB mem)
    • Large - 3 x Control Plane Node (8 vCPU & 12GB mem) + 4 x Worker Node (24 vCPU & 48GB mem)


While the Simple VCF deployment model is ideal for lab and proof-of-concept environments, it is also a good fit for smaller production environments. However, the only way to provide HA for VCF Management Services (VCFMS) using the VCF Operations Fleet LCM UI is by scaling up to either a Medium or Large deployment, which comes with additional worker nodes and increased resource consumption.

If only we had a way to enable high availability for a Small VCFMS deployment? 🤔
