When launching an Amazon EC2 instance, you often need to automate the installation of packages, configuration of services, and setup of applications. AWS provides two primary approaches for this **User Data** scripts and **cfn-init** (CloudFormation helper script). Each has its own strengths and limitations. In this blog post, we'll explore both, compare their pros and cons, and explain how you can use `cfn-hup` to automate in-place updates. -

In this blog post, we will explore how to create an autoscaling group with a target tracking policy using AWS CloudFormation. We'll delve into the concepts of autoscaling groups, different scaling policies, and why AWS recommends using target tracking policies. Additionally, we will walk through an example that demonstrates the behavior of an autoscaling group in response to CPU utilization changes. -

Simulating precise CPU utilization is essential for testing applications and systems under controlled conditions. For example, when evaluating system performance or auto-scaling behavior, you may want to set CPU usage to a specific percentage. This post introduces a Python script that combines `stress` and `cpulimit` to achieve this, offering a flexible way to simulate exact CPU loads. -

Cloud computing is a big deal these days, and the best way to learn it is by getting your hands dirty with real projects. That’s why I decided to build a **TODO app using AWS**. This wasn’t just about making a simple app to manage tasks—it was about learning AWS inside out, mastering CI/CD pipelines, and getting ready for the **AWS Developer Certification Exam**. Along the way, I also wanted to explore how to build scalable and secure systems, and get comfortable with deploying and managing cloud applications. -
