Introduction

Hello everyone! My name is Sohail and I recently completed my Computer Science degree.

I am starting a 90-days DevOps learning journey to strengthen my skills in Linux, Networking, Git, Docker, AWS, and CI/CD.

This blog will serve as a public record of my learning, projects, challenges, and achievements.

Why DevOps?

- DevOps combines development and operations practices to improve collaboration, automate workflows, and deliver software more efficiently.

• Automation
