A Deep Dive into Layer 7 vs Layer 4 Traffic Management 📌 Introduction When designing scalable and highly available cloud architectures in Microsoft Azure, one of the most critical decisions engineers face is: 👉 Should I use Azure Load Balancer or Azure Application Gateway? While both services distribute traffic, they operate at different layers of the OSI model and are built for completely different use cases. Understanding this distinction is essential for building secure,

A Complete Hands-On Guide for High Availability and Scalability 📌 Introduction In today’s cloud-native world, ensuring high availability and seamless scalability is non-negotiable. One of the core services that enables this reliability in Microsoft Azure is the Azure Load Balancer. In this hands-on lab, we implemented a Standard Azure Load Balancer and configured its essential components, including backend pools, health probes, and load balancing rules, to efficiently distri

📘 Overview In this hands-on lab, we explore how to configure Azure Virtual Network (VNet) Peering, a key feature that allows seamless communication between Azure virtual networks. We’ll walk through: Understanding the scenario Configuring VNet peering Creating virtual machines using Azure PowerShell (Aditional step) Testing the peering connection 🧠 Scenario You are working as an Administrator, and if you have task to connect two Azure virtual networks. The goal is to enable

When HCX migrations or network extensions misbehave, most engineers instinctively start checking firewall rules, routing, or DNS. That’s necessary—but it’s not always the fastest approach. HCX includes a powerful built-in feature called Data‑Plane Diagnostics that helps you validate site‑to‑site data‑plane connectivity and quickly pinpoint why a Service Mesh tunnel is down, degraded, or behaving inconsistently. This blog explains what Data‑Plane Diagnostics is , how to run

Situation: This blog post provides a detailed, step-by-step guide on how to collect SDDC Manager logs, which can be essential for troubleshooting issues or conducting diagnostics within a VMware Cloud Foundation (VCF) environment. Procedure: SSH to SDDC Manager, switch to "root". Run the following command to begin collecting the SDDC Manager logs. # /opt/vmware/sddc-support/sos --sddc-manager-logs --zip Note: If you need to collect logs for a specific domain or the NSX Manag

In a VMware vCenter environment, managing ISO files across multiple datastores can be a cumbersome task. If you have numerous ISO files that need to be deleted, doing it manually is time-consuming and prone to errors. Thankfully, PowerShell, combined with VMware PowerCLI, can automate this process efficiently. Prerequisites: Before running the script, ensure you have "VMware PowerCLI" installed, if not then below is the command line to install it. # Install-Module -Name VMwar

If you've ever needed to manage a multitude of ISO files across multiple datastores in a VMware vCenter environment, you know how time-consuming and error-prone it can be to manually search for these files. That's where PowerShell comes in handy! By leveraging PowerShell scripts, you can automate the process of retrieving information about all ISO files from datastores, saving you time and reducing the risk of human error. Why PowerShell? PowerShell is a powerful scripting la

Sometimes VMware's depot is just down or facing depot connection issue. First off, verify the "VMware Customer Connect Depot" connection status from SDDC UI. Administration > Online Depot Start off with a simple ping to verify SDDC network connection with Depot. SSH into your SDDC Manager as vcf and su to root. # ping depot.broadcom.com Can you can ping from the SDDC Manager? If you can, most likely you aren't having a connection issue. SSH into your SDDC Manager as vcf and s

Sometime you are required to remove the old upgrade and installed bundles to free up space on your SDDC Manager. In this blog post, we will see the instructions for removing old upgrade and installed bundles. Supported Environment: VMware Cloud Foundation 3.x VMware Cloud Foundation 4.x Procedure: UI login to SDDC Manager. Go to Lifecycle Management > Bundle Management > Download History. Take a note of Bundle ID that needs to be deleted/cleanedup. Create a snapshot of the SD

Issue: While performing VCF upgrade from 4.5.2 to 5.2.1, we observed when selecting the "Customize Upgrade" before the vCenter upgrade, it doesn't load and populate for customization options. Cause & Task: This occurs if there is any stale 6.x vCenter bundle reference existing in the LCM database. Check if there was any old & stale 6.x or 7.x vCenter bundle available in downloaded history in SDDC Manager. Resolution: Take a snapshot of the SDDC Manager VM. SSH into the SDDC m

In environments with many ESXi hosts, managing hosts with scripts is faster and less error prone than managing the hosts from the vSphere Client. VMware PowerCLI is a Windows PowerShell interface to the vSphere API, and includes PowerShell cmdlets for administering vSphere components. ESXCLI includes a set of commands for managing ESXi hosts and virtual machines. Situation: While ESXi host hypervisor & firmware upgrade, there was a requirement for all ESXi host's advance sett
