Deploying a Supervisor in VCF 9: What Actually Matters

Sat, 21 Mar 2026 00:00:00 +0000

Deploying a Supervisor in VMware Cloud Foundation 9 is often presented as a simple workflow inside the vSphere Client. In reality, the deployment wizard is the easy part. What actually determines success is the design work that happens before the wizard is ever opened.

A Supervisor can deploy successfully and still fail to deliver a usable platform if the surrounding networking, routing, load balancing, storage, and automation decisions were not made intentionally. That becomes even more important when the goal is not just enabling Kubernetes for demonstration purposes, but building a real platform that can support namespaces, services, VMware vSphere Kubernetes Service, and modern consumption models in VCF Automation.

Deploying and Using the VMware Health and Security Toolkit (HST)

Tue, 10 Mar 2026 00:00:00 +0000

The VMware Health and Security Toolkit (HST) is a platform provided by Broadcom that helps administrators perform health checks, configuration validation, and security assessments across VMware infrastructure environments.

The tool collects configuration data from components such as:

vCenter Server
ESXi Hosts
Virtual Machines
vSAN
NSX
SDDC Manager

It then analyzes the collected data against security controls and best practices to identify potential risks or configuration issues.

This guide walks through the full process of deploying and using the HST appliance, including environment validation and reviewing generated security reports.

Understanding Cost Modeling in VMware Cloud Foundation Operations

Sat, 07 Mar 2026 00:00:00 +0000

One of the most common questions in private cloud environments is how infrastructure cost translates into workload consumption. Organizations want to understand not only how much their platform costs to operate, but also which workloads are consuming the most resources and driving that cost.

VMware Cloud Foundation Operations includes a cost modeling framework that estimates the Total Cost of Ownership for a private cloud platform and distributes that cost across workloads based on resource utilization. This allows administrators and leadership to visualize how infrastructure resources are consumed across the environment.

Building an Executive Cost Dashboard in VCF Operations

Creating a Custom Executive Cost View in VCF Operations
#

Before building any meaningful dashboard in VCF Operations, it is critical to establish a structured data foundation. Dashboards are only as effective as the views that power them. Rather than relying on default widgets, this implementation begins by creating a reusable cost-focused List View that surfaces VM-level financial metrics in a structured and executive-ready format.

From VCF 5.2 to VCF 9: What Modernization Actually Looks Like

Thu, 26 Feb 2026 00:00:00 +0000

When customers talk about upgrading VMware Cloud Foundation, it sounds simple.

Just upgrade to the latest version.

In reality, moving from VCF 5.2 to VCF 9 is not an upgrade. It is an architectural transition.

Over the past several months, I’ve had the opportunity to support that transition in a federal environment. Here are the biggest lessons.

When I stepped into this engagement, the environment was running VCF 5.2.
