Development and Operations (DevOps)

ABSTRACT

DevOps is the collection of cultural practices, philosophies, mechanisms, and technology that assists in increasing the ability of an organization to distribute services and applications at a faster pace. Unlike the traditional software development and infrastructure management processes (also known as the Waterfall Model), DevOps is inspired from the Agile Project Management, meaning that the entire project is broken down into several phases, aiming for continuous improvement at every phase.

The DevOps cycle is a loop divided into eight different phases: PLAN, CODE, BUILD, TEST (in Development sub-cycle) and RELEASE, DEPLOY, OPERATE, MONITOR (in Operations sub-cycle). Also, the phases are categorized into 6 Cs: Collaborative Business Planning, Continuous Integration, Continuous Testing, Continuous Delivery, Continuous Deployment and Continuous Monitoring. Different tools and applications are used for each phase of the cycle. DevOps is targeted to maximize the efficiency, maintainability, predictability, and security of the entire project by breaking the barrier between development (Dev) and operations (Ops) teams. This approach was denoted to fix the inefficiencies highlighted by the Waterfall model such as improved deployment frequency, lower failure rate for releases, shorter maintenance breaks, improved quality testing, frequent feature development and feedback and better communication between business planning team, developers and IT operators. This is the reason DevOps is popular among majority of organizations, software vendors and tech-giants. This report comprises the detailed information about the DevOps approach, including its history, working principle, characteristics, tools and technology, newer disciplines, and real-life examples.
