Fixing Tanzu Kubernetes Pod to External Services Connectivity Issues with NSX-T Last month I got a call from a customer who was pulling their hair out over a networking issue. They had just deployed VMware Tanzu Kubernetes Grid on their vSphere with Tanzu environment, everything looked good in the dashboards, all pods were running, but their applications inside the pods could not reach external databases running on traditional VMs in the same datacenter. The frustrating part was that some pods could reach external services perfectly fine, while others would just timeout. There was no clear pattern. Let me tell you how we figured this out and fixed it. The Initial Problem Here is what the customer setup looked like: vSphere 8.0 with Tanzu enabled NSX-T 4.1.2 for networking Three Tanzu Kubernetes clusters running different microservices applications External PostgreSQL database running on traditional VMs (non-Kubernetes) External API services running on another se...

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...

Introduction :  Hybrid cloud environments are becoming increasingly popular among enterprises due to their flexibility, cost-efficiency, and disaster recovery capabilities. Broadcom and VMware, two industry leaders, offer robust solutions that can optimize hybrid cloud environments. This article explores how their technologies can be integrated to enhance performance, scalability, and security. Understanding Hybrid Cloud :  Hybrid cloud environments combine private and public cloud resources, allowing businesses to leverage the best of both worlds. Key benefits include: Flexibility:  Easily scale resources up or down based on demand. Cost-Efficiency:  Optimize costs by using public cloud resources for non-sensitive workloads. Disaster Recovery:  Ensure business continuity with robust disaster recovery solutions. Broadcom’s Contributions:  Broadcom provides a range of technologies that support hybrid cloud environments, including: Network Switches:  Bro...

Just off from the VMworld 2017 US event. As always VMware featured a number of great announcements at VMworld 2017 including VMware Cloud on AWS. VMware customers can now run new or existing virtualized workloads in the AWS cloud while maintaining their current VMware tools and skill sets This announcement provides an important shift in the hybrid cloud market for businesses looking to adopt the agile flexibility and services of cloud while preserving infrastructure and investments in the datacenter Another BIG announcement was VMware and Pivotal Launch Pivotal Container Service (PKS) and Collaborate with Google Cloud to Bring Kubernetes to Enterprise Customers.     New Pivotal Container Service™ (PKS) Delivers a Simple Way to Deploy and Operate Production-Ready Kubernetes on VMware vSphere® and Google Cloud Platform (GCP)        PKS Features Kubernetes Distribution Built on Kubo, an Open Source Technology Created by Pivo...
