Hey everyone! ?? Just wrapped up Day 40 of my #90DaysOfDevOps challenge, and I'm beyond excited to share my experience with you all. Today's task took me into the world of Amazon EC2, automation, and some mind-blowing features that I had only heard about before. Let's dive in!
Task1: Crafting an EC2 Launch Template
Today's adventure started with creating an EC2 launch template. ?? Armed with an Amazon Linux 2 AMI and a t2.micro instance type, I took it a step further by setting up Jenkins and Docker using the User Data script from Day 39. The template held the key information—AMI ID, instance type, and network settings—that I usually input manually. Talk about a time-saver! ??
The best part? Now, every time I want to spin up a new instance with this specific setup, all I need to do is choose the launch template. Streamlining the process and reducing errors? Check! ??
Scaling Up: Launching 3 Instances at Once
But that's not where the fun ended. I took things up a notch by launching not one, not two, but three instances using the newly minted launch template. ?? The icing on the cake? The option to specify the number of instances I wanted to launch. A tiny detail with a massive impact! This simple feature opened up a whole new world of efficiency and consistency in deployment. I'm all about making life easier, and this absolutely hit the spot. ??

Going the Extra Mile: Auto-Scaling Group
Now, for the real challenge: auto-scaling groups. ?? The idea of creating an auto-scaling group sounded pretty daunting at first. But as they say, "No pain, no gain!" With a bit of courage and a lot of determination, I went ahead and delved into it.
An auto-scaling group dynamically adjusts the number of instances based on predefined conditions. It's like the magic wand of scalability—keeping your application running smoothly even when the workload changes. It was a bit tough to wrap my head around initially, but the feeling of accomplishment when I got it working was unbeatable. ??
