DevOps

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). The goal of DevOps is to shorten the systems development life cycle and provide continuous delivery with high software quality. DevOps aims to automate and integrate the processes between software development and IT teams, so they can build, test, and release software faster and more reliably.

In practice, DevOps emphasizes cross-functional collaboration, continuous integration, continuous delivery, infrastructure automation, and monitoring & observability. For example, developers write code and use version control tools like Git to track changes. The code is merged into a shared repository that triggers automated builds and tests. If these steps pass, the software can be automatically deployed to production environments through infrastructure automation tools like Kubernetes. Monitoring tools then provide feedback on software performance to improve quality. The faster feedback loops allow teams to release features in an agile way. Overall, DevOps streamlines software delivery by bringing development and operations together with practices like CI/CD pipelines, infrastructure as code, microservices, and monitoring.
