Introduction to DevOps
DevOps is not a tool or a team, it is the process or a methodology of using various tools to solve the problems between the Developers and the Operations team in an organization, hence the term came “Dev-Ops”.
The development team always had the pressure of completing the old, pending work that was considered faulty by the operations team. With DevOps, there is no wait time to deploy the code and getting it tested. Hence, the developer gets instantaneous feedback on the code, and therefore can close the bugs, and can make the code production ready faster!
The business Values of DevOps
2018 was proclaimed the year of enterprise DevOps by Forrester, as more than 50% of enterprises worldwide have already done their DevOps transformation or are in the process of it. Here We will explain this below, with some examples of how DevOps helps companies across various industries succeed.
In short, implementing DevOps best practices and workflows helps businesses save time and money, increase software lifecycle predictability, build a corporate culture around innovation and keep motivation levels high. We will discuss it in detail.
DevOps Saving time and money: DevOps principles of IaC, CI, and CD help ensure the uniformity of task scenarios and infrastructure immutability, so automation becomes 100% efficient and helps greatly reduce the amount of time and effort spent on routine and repetitive tasks.
Tools you’d use in the commission of these principles. In the DevOps world, there’s been an explosion of tools in release (Jenkins, Travis, TeamCity), configuration management (puppet, chef, ansible, cfengine), orchestration (zookeeper, Noah, Mesos), monitoring, virtualization and containerization (AWS, OpenStack, vagrant, docker) and many more. While, as with Agile, it’s incorrect to say a tool is “a DevOps tool” in the sense that it will magically bring you DevOps, there are certainly specific tools being developed with the express goal of facilitating the above principles, methods, and practices, and a holistic understanding of DevOps should incorporate this layer.
Most Influential Benefits Of DevOps
Speed: DevOps practices let you move at the velocity you need to innovate faster, adapt to changing markets better, and become more efficient at driving business results.
Rapid delivery: When you increase the pace of releases, you can improve your product faster and build a competitive advantage.
Reliability: DevOps practices like continuous integration and continuous delivery can ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining an optimum experience for end-users.
Improved collaboration: Under a DevOps model, developers and operations teams collaborate closely, share responsibilities, and combine their workflows. This reduces inefficiencies and saves time.
Security: You can adopt a DevOps model without sacrificing security by using automated, integrated security testing tools.
DevOps is a revolution that aims at addressing the wall of confusion between development teams in big corporations having large IT departments where these roles are traditionally well separated & isolated.
Now, what about smaller corporations that don’t necessarily have split functions between developers & operations?
Adopting DevOps principles & practices, such as deployment automation, continuous delivery and flipping still bring a lot.
