DevOps
DevOps is a set of practices, cultural philosophies, and tools that combine software development (Dev) and IT operations (Ops) to shorten the systems development life cycle and provide continuous delivery with high software quality. It emphasizes collaboration, automation, monitoring, and integration between development and operations teams to enable faster and more reliable software releases.
Developers should learn and use DevOps to improve deployment frequency, reduce lead time for changes, and lower failure rates in production, making it essential for modern software delivery. It is particularly valuable in agile environments, cloud-native applications, and microservices architectures where rapid iteration and reliability are critical, such as in e-commerce, SaaS platforms, and large-scale web services.
