DevOps combines the words "development" and "operations." It may be used to 1) encompass developers and IT operations personnel as a single group or 2) describe the integration of the two divisions within a company.
The goal of DevOps integration is to improve collaboration between development and operations teams. An operations manager, for example, may request an update to a web application from the developers. In order for the update to be successful, the operations team must accurately describe all the necessary features of the update. The development team can then implement the update and test it internally before releasing it to the operations team for production.
A DevOps process for software updates might include the following steps:
- Receiving and processing user feedback (Operations)
- Designing the update (Operations and Development)
- Coding and implementing the update (Development)
- Testing the update internally (Development)
- Publishing the update to production (Operations)
- Testing the live update (Operations and Development)
The above steps are just one example of how a DevOps process might take place. There is no specific set of steps a company must follow. A small company, for instance, may have fewer steps and more overlap between divisions than a large corporation. The end goal of DevOps, regardless of company size, is to produce reliable software in the shortest time possible.
Ways to improve DevOps workflow include:
- Creating identical testing and production environments
- Automating software tests, such as unit testing
- Designing software that is easily scalable
- Using version control to keep track of changes
NOTE: A "DevOps Manager" is a relatively new position in the field of information technology. The role of a DevOps manager is to oversee both the development and operations teams, helping them communicate and work together effectively.
