DevOps is a collaborative approach that merges software development (Dev) and IT operations (Ops) to improve efficiency, speed, and quality in delivering applications. Here's a quick guide to get started:

Key Principles of DevOps

  • Automation: Use tools like Jenkins or GitLab CI for CI/CD pipelines 🤖
  • Infrastructure as Code (IaC): Manage resources via Terraform or AWS CloudFormation 📁
  • Continuous Feedback: Implement monitoring with Prometheus or Grafana 📊
  • Culture of Collaboration: Break down silos between developers and operations 🔨

Essential Practices

  1. Version Control
    Use Git for code management and collaboration 🧾
    Learn more about Git workflows

  2. Automated Testing
    Integrate unit, integration, and acceptance tests into your pipeline 🧪
    Example: 

    npm test || exit 1

  3. Containerization
    Package applications with Docker for consistent environments 🐳
    Explore Docker basics

  4. Orchestration
    Deploy containers using Kubernetes for scalability 📦
