What is DevOps?
DevOps is a method of IT delivery that integrates people, practices, and tools. It helps to eliminate silos between operations and development teams. DevOps teams speed up the development of services and applications. They also have a more responsive approach for managing the IT infrastructure and can deploy and update IT products quickly to meet the needs of modern markets.
DevOps bridges “dev” and operations. In other words, software development is where the code behind the applications is created and IT operations where those applications are put into production and made available to end users. DevOps was born out of two previous trends: the agile development movement, and lean manufacturing principles. The former encourages quick sprints and rapid iteration in order to build a responsive IT development organization. The latter minimizes waste and maximizes productivity at factories.
DevOps eliminates the bottlenecks associated with agile development. Traditional operations teams will have a harder time getting the software live and tested if agile developers produce new code or updates more frequently than traditional ones. This can lead to a loss of the true value of rapid development. Although agile made software design and construction more flexible and iterative, the approach didn’t extend to the entire software development lifecycle (SDLC), or into deployment.
Principals of DevOps
DevOps, as a culture and philosophical approach, is committed to continuous improvement, collaboration, transparency, and transparency. DevOps views IT operations holistically as a means to increase value. It does not focus on specific work areas, but the whole flow, from initial idea to product or functionality. This is done with an eye towards maximizing business value and achieving it at a faster rate. DevOps teams that perform well see faster code iterations, deployments, and overall shorter time to market for new ideas and bugs, as well as fewer bugs, and a more stable infrastructure.
Every successful DevOps program has a few core principles and concepts. These principles, along with the right process and tools, will make DevOps a success for teams. Although DevOps is unique for every organization and each team, these are some starting points:
- Ownership in part:Effective collaboration relies on shared ownership–understanding and embracing that everyone is responsible and contributes to the work in some way. Every person involved in building, maintaining, or contributing to the final product knows they have a stake. In the DevOps paradigm, the old way of throwing work at other teams is no longer possible.
- Automation of workflow:Automating can improve consistency, reliability, efficiency, and make it easier to fix bugs and problems. We can avoid the trap of institutional know-how, which is where certain people only know how to do certain tasks.
- Rapid response:Teams can quickly see the impact of changes made throughout the software development lifecycle by automating repetitive tasks such as testing and reporting. This understanding allows teams to work more efficiently together, since coders can pass changes from testers to coders, builders to testers, testers back to coders and so on. Developers and operations teams can get rapid feedback to help them make better decisions and implement changes based upon shared data.
