In 2009 Patrick Debois coined the term by naming a conference"devopsdays" which began in Belgium and has spread to other nations. Basically it acts as a bridge between software development and software operation. So, the term DevOps was kept in that way.
DevOps is a set of practices intended to decrease the time between committing a change to a system and the shift being put into normal production, while ensuring high quality.
There are many advantages to adopting a DevOps culture. Systems get delivered faster and more affordable, and they are often of better quality. Industry observers say DevOps provides a more efficient method of conducting technology-intensive companies. Some of the main features are:
1. Shorter Development Cycles, Faster Innovation
When operations and development teams are in different silos, it is usually tough to tell if an application is ready for operations. When development teams only turn over an application, the operations' cycle times are extended needlessly.
2. Reduced Deployment Failures, Rollbacks, and Time to Recover
Part of the reason teams encounter deployment failures is due to programming flaws. The shorter growth cycles with DevOps promote more regular code releases. This, then, makes it much easier to spot code flaws. Therefore, teams can reduce the amount of installation failures using agile programming principles which involve cooperation and modular programming. Rollbacks are similarly simpler to manage since, when necessary, just some modules are changed.
3. Improved Communication and Collaboration
DevOps enhances the software development culture. Combined teams are happier and more effective. The culture becomes more focused on performance instead of individual objectives. When the teams trust each other, they could innovate and experiment more effectively.
Higher efficiency can help to accelerate the development process and make it less prone to error. There are ways to automate DevOps tasks. Constant integration servers automate the process of analyzing code, reducing the amount of manual work required.
5. Reduced Costs and IT Headcount
All the DevOps benefits translate to lower overall costs and IT headcount requirements. Based on Kevin Murphy from Red Hat, DevOps development teams need 35 percent less IT employees and 30 percent lower IT costs.
DevOps professionals are among the highest paid IT professionals now, and the market demand for them is growing quickly because organizations utilizing DevOps practices are overwhelmingly high-functioning. According to a very recent report published by Puppet labs: State of DevOps Report, business company, IT company, and corporate office using DevOps approach deploy code around 30 times more often than their opponents, and 50 percent fewer of the deployments fail.
In the last two decades, listings for DevOps jobs on Indeed.com increased 75 percent. On LinkedIn.com, cites of DevOps as a skill increased 50 percent.
