What Is DevOps?
The essence of DevOps is to leverage native, well-known tools and processes in an agile and iterative fashion in teams that are self-sufficient and capable of rapid and frequent, even daily, code releases. The use of native tools by developers and IT professionals allows a low threshold for the adoption DevOps, resulting in a highly automated, high-frequency release cycle, instead of the release-per-year approach of the traditional waterfall development model.
