Introduction

DevOps has revolutionized the tech industry by bridging the gap between development and operations. As a DevOps Engineer, you will streamline processes, automate workflows, and ensure seamless software deployment. This guide outlines the skills, tools, and roadmap needed to become a successful DevOps Engineer in just nine months.

What is DevOps?

DevOps is a combination of development and operations, focusing on:

  • Collaboration: Bridging the gap between software developers and IT operations teams.
  • Automation: Streamlining repetitive tasks like testing and deployment.
  • Continuous Integration/Continuous Deployment (CI/CD): Rapid and reliable software delivery.

Why DevOps?

  • High demand for DevOps skills in software teams.
  • Competitive salaries: Average $100,000–$150,000/year.
  • Opportunities to work on cutting-edge technologies like cloud computing, containerization, and microservices.
