Lesson 1: Introduction to DevOps

What is DevOps?

DevOps is a culture, mindset, and set of practices that combines software development (Dev) and IT operations (Ops) to deliver applications faster, more reliably, and at scale.

Core DevOps Principles

• Continuous Integration (CI): Integrating and testing code frequently.
• Continuous Deployment (CD): Automatically releasing code to environments.
• Infrastructure as Code (IaC): Managing servers and cloud resources using code.
• Monitoring & Logging: Observing system health and application behavior.
• Collaboration & Communication: Breaking silos between teams.

Why DevOps is Important

• Faster software delivery
• Reduced deployment failures
• Improved system stability
• Better visibility and accountability
