In traditional IT organizations, developers wrote code and then “tossed it over the wall” to operations teams, who were responsible for deploying and maintaining it. This separation led to bottlenecks, finger-pointing, and slow delivery. Enter DevOps: a movement that blends development and operations into a unified process.

What is DevOps?

DevOps is less about tools and more about culture. It emphasizes collaboration, automation, and continuous feedback. Instead of treating code delivery as a one-time event, DevOps encourages continuous integration and continuous delivery (CI/CD).

Why is it important?

  • Speed: Automated pipelines reduce the time between writing code and getting it into production.
  • Quality: Frequent testing and monitoring catch issues early.
  • Collaboration: Developers and operations work as one team with shared goals.

Popular DevOps practices

  • Infrastructure as Code (IaC): Tools like Terraform let teams manage servers the same way they manage code.
  • Containerization: Docker and Kubernetes package applications consistently across environments.
  • Monitoring: Real-time logging and metrics provide visibility into performance.

DevOps is not just a technical practice; it’s a mindset. Teams that adopt DevOps tend to innovate faster, recover from failures more gracefully, and provide a better user experience.
