DevOps

Development & Operations

DevOps is a set of practices, tools, and cultural philosophies that automate and integrate the processes between software development and IT operations teams. It emphasizes collaboration, communication, and integration between developers and operations professionals to improve the speed and quality of software delivery.

Key DevOps Practices

  • Continuous Integration (CI): Automatically integrating code changes
  • Continuous Deployment (CD): Automated deployment to production
  • Infrastructure as Code: Managing infrastructure through code
  • Monitoring & Logging: Real-time application and infrastructure monitoring
  • Microservices: Breaking applications into smaller, manageable services
