๐ What is DevOps Engineering?
DevOps is a software development methodology that combines software Development (Dev) and IT Operations (Ops) to shorten the systems development life cycle and provide continuous delivery with high software quality. A DevOps Engineer is a professional who facilitates this collaboration, automating processes, and ensuring seamless software releases.
๐ A Brief History of DevOps
The term 'DevOps' emerged around 2009, born from the need to address the inefficiencies and silos between development and operations teams. Traditional software development often involved developers working separately from operations, leading to delays and conflicts during deployment. DevOps aimed to break down these barriers by fostering a culture of shared responsibility and automation.
