DevOps is a work philosophy that unites development (Dev) and operations (Ops) teams to make software delivery faster, more efficient, and more reliable. Through automation, continuous integration, and collaboration, DevOps helps reduce errors, improve software quality, and accelerate time to market. Companies that adopt DevOps achieve more agile processes and less downtime in their applications. It sounds complicated, but it's basically about everyone working together with modern tools so that things run smoothly.
