Intro: A VMSS is an Azure compute resource that lets you deploy and manage a set of identical, load-balanced VMs.
It’s designed for scalability: you can automatically increase or decrease the number of VMs based on demand.
Great for workloads like web apps, microservices, or big data processing.
Steps to Create a VMSS
- Sign in and start the VMSS wizard
Open: Azure Portal → search for “Virtual Machine” → select it.
Action: Click “Create.”
- Basics tab configuration
Subscription & resource group: Select your subscription; create a new resource group (e.g., “rgvmss”).
Scale set details: Name (e.g., “vmss-web-uk”), Region (e.g., UK South), Orchestration (Flexible is recommended), Image (Ubuntu or Windows).
Authentication: SSH key (Linux) or password (Windows); set admin username.
Instance details: Choose size (e.g., Standard_DS1_v2) and initial instance count (e.g., 2).
