Introduction to DevOps

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the systems development life cycle while delivering features, fixes, and updates frequently and reliably. It emphasizes collaboration, automation, and integration between development and operations teams to improve deployment frequency and maintain system stability.

Why We Recommend It

We recommend DevOps practices because they significantly enhance productivity and reliability in software development. By implementing automated testing, continuous integration, and infrastructure as code, teams can deploy more frequently with fewer errors. Organizations adopting DevOps typically experience faster time to market, improved quality, and greater ability to respond to customer needs. The cross-functional skills acquired through DevOps also make team members more versatile and valuable in today's technology landscape.
