What is DevOps?

  • DevOps is a methodology that bridges the gap between software developers and IT operations teams
  • It emphasizes automation, monitoring, and continuous feedback
  • DevOps improves efficiency, security, and collaboration in software development

Learn more about What is DevOps?

Key Principles of DevOps

  • Collaboration – Development and operations teams work together
  • Automation – Reduces manual efforts in testing, deployment, and monitoring
  • Continuous Integration (CI) – Developers frequently integrate code changes
  • Continuous Deployment (CD) – Software is automatically deployed after testing
  • Monitoring & Feedback – Real-time monitoring to detect and fix issues
