1. What is DevOps?

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the software development lifecycle while delivering high-quality software continuously. DevOps encourages a collaborative culture by merging traditionally siloed teams to automate processes, monitor systems, and reduce the time between development and deployment.

2. The Key Principles of DevOps

DevOps rests on a few core principles:

• Collaboration: Breaking down silos between development, operations, and QA teams.
• Automation: Automating repetitive tasks such as testing, building, and deployments.
• Continuous Improvement: Regularly improving systems, processes, and tools for efficiency.
• Monitoring and Feedback: Continuously monitoring applications and infrastructure for feedback.

These principles help deliver software faster and with more stability, enhancing customer satisfaction.

3. Skills You Need to Become a DevOps Engineer

Core Technical Skills

1. Linux/Unix Fundamentals: Most DevOps tools and servers run on Linux, so you need to be comfortable with its commands, scripting, and system administration.

   • Resource: Linux Basics for DevOps Engineers

2. Scripting Languages: Automation is key in DevOps. Learn scripting languages like:

   • Bash: Basic command-line scripting.
   • Python: Widely used for automation and scripting.
   • Ruby: Used in infrastructure-as-code tools like Chef.
   • Resource: Python for DevOps

3. Version Control Systems (Git & GitHub): Understanding Git is fundamental in DevOps for tracking changes in code.
