Introduction

Scalability is not just a feature but the backbone of any modern application. With Linux Virtual Machine Scale Sets (VMSS), you are not just deploying virtual machines; you are creating a dynamic system that effortlessly adjusts to your needs.
Imagine your app thriving under unpredictable spikes in traffic or your microservices running smoothly without manual intervention. VMSS makes it happen, blending adaptability with simplicity.
Here is your gateway to mastering scalable systems, where you will create a Linux VM Scale Set and learn to connect and make it work for you efficiently and intelligently. Let’s get started.

Procedure

1. Set Up Your Environment
   • Log in to your cloud platform (e.g., Azure).
   • Ensure you have a resource group and a virtual network created.
2. Create the Scale Set
   • Navigate to the Virtual Machine Scale Sets section.
   • Click Create and configure:
   • Name: Assign a unique name.
   • Region: Select the desired region.
   • Orchestration Details: Select uniform mode
3. Configure Scaling Settings
   • Enable autoscaling and set scaling configuration parameters such as:
   • Minimum and maximum instance limit.
   • Minimum and maximum instance count.
   • Scaling trigger (e.g., CPU usage percentage).
   • Query duration
   • select save
   • Choose scale-in policy and then save
   • Complete the instance details on the virtual machine: Choose a Linux image, VM size.
4. Set Up Networking
   • Attach the scale set to your virtual network.
   • Configure inbound NAT rules to allow SSH access to individual instances
   • Configure virtual network machine load balancing
   • Select azure load balancer
   • Create a load balancer: Choose a name and accept all default, then create.
   • select review + create.
5. Deploy the Scale Set
   • Review the configurations and click "Create."
   • Download private key and create resources
   • Wait for the deployment to complete.
6. Connect to an Instance
   • Connect to load balancer
   • Obtain the public IP and port for an instance from the load balancer or NAT rules.
   • Use SSH to connect:ssh <username>@<public-ip> -p <port>
7. Monitor and Optimize
   • Use the cloud platform’s monitoring tools to track performance.
   • Adjust scaling rules and VM configurations as needed.
