The evolution of VMware under Broadcom represents not disruption, but clarification—a focused vision toward unified private cloud excellence. As organizations navigate this transformation, the opportunity has never been greater to build truly modern, efficient, and powerful infrastructure with VMware Cloud Foundation. After architecting VMware solutions across diverse enterprise environments, I've observed a pattern: organizations that embrace VMware Cloud Foundation (VCF) strategically—rather than viewing the transition as a burden—emerge with significantly more capable, cost-effective, and future-ready infrastructure. This post shares a practical framework for successfully modernizing your VMware environment, maximizing your investment, and positioning your organization for the AI-driven, cloud-native future. Understanding the VMware Cloud Foundation Vision Let's start with clarity about what Broadcom and VMware are building: VMware Cloud Foundati...

In enterprise VMware environments, maintaining architectural standards at scale is a constant challenge. After years of working with large-scale virtualisation infrastructures, I've learned that the gap between what architects design and what exists in production grows exponentially with team size and deployment velocity. This post shares my hands-on experience building automated guardrails and conformity bots that enforce standards, detect drift, and maintain architectural hygiene across VMware estates. The Real Problem: Configuration Entropy Every VMware environment I've worked with faces the same pattern. It starts clean—well-tagged VMs, proper resource allocation, consistent network segmentation. Six months later, chaos. VMs get deployed without mandatory tags, making cost tracking nearly impossible Resource limits get bypassed during urgent deployments and never corrected Network placement becomes inconsistent as different teams interpret po...

Customers who uses NSX day-in, day-out would like to have a point-in time restore functionality of DFW firewall rules. Many customer have a large footprints in VMC and make changes to DFW quite often. This feature was missing for long time and we could see its included in recent versions . Let's see how DFW configuration roll back works  NSX DFW configuration has versioning, and it is stored in the NSX Manager.  Every time when someone update DFW configuration, NSX creates one more version but keep storing the previous ones. You can rollback for previous config but reapplying it once again.  You can find the options under Networking & Security tab , > Security > Distributed Firewall . In the right side we see an Actions drop down. Choose View to get to the below screen.  Let’s go through the use case:  1. Original state- default config with no custom rules:  a. There are no saved configurations during last 30 days: In my existing test setup, ...

This post is related to the issue what we faced today when we replaced the SSL certificates in our setup.  When I launched the web-client and access the update manager tab,  I get the message  "interface com.vmware.vim.binding.integrity.VcIntegrity is not visible from class loader" I started off by restarting the VMWare vSphere Update Manager Service for the affected vCSA: 1. Log into vCenter using the administrator@vsphere.local account. 2. Home - System Configuration - Services - Restart This did not resolve my issue...  And we tried restarting all the services by  SSH/Console into the affected server and run the following commands: service-control --stop --all service-control --start --all Still no luck.  Make sure the certs are applied and it gets reflected in the config file. ( verify if the thumbprint matches)  root@homelab71 [ /usr/lib/vmware-updatemgr/bin ]# pwd /usr/lib/vmw...

vSphere 6.5 brings a number of enhancements to ESXi host lifecycle management as well as some new capabilities to our venerable resource management features, DRS and HA.  There are also greatly enhanced developer and automation interfaces, which are a major focus in this release.  Last but not least, there are some notable improvements to vRealize Operations, since this product is bundled with certain editions of vSphere.  Let’s dig into each of these areas. Enhanced vSphere Host Lifecycle Management Capabilities With vSphere 6.5, administrators will find significantly easier and more powerful capabilities for patching, upgrading, and managing the configuration of VMware ESXi hosts. VMware Update Manager (VUM) continues to be the preferred approach for keeping ESXi hosts up to date, and with vSphere 6.5 it has been fully integrated with the VCSA.  This eliminates the additional VM, operating system license, and database dependencies of the...
