Like all work cultures, DevOps is adopted and applied in different ways from organization to organization. Nevertheless, certain capabilities are common in nearly all DevOps implementations. What are DevOps key characteristics?
Instead of operations and development teams assuming a defensive or combative stance when engaging one another, they strive to collaborate. The conflicts and rivalry between these teams are one of the principal catalysts for the creation of DevOps.
DevOps is geared toward facilitating the speedy delivery of an agile development project. Therefore, it is heavily dependent on automation. That means a reliance on multiple tools that automate the application development and deployment cycle.
Continuous integration is a technique for continually merging software code from all developers in a project into a shared mainline. This ensures that the copy of the project each developer is working on is nearly the same. By compelling developers to integrate their work into the mainline at least daily, DevOps culture reduces the likelihood of disruptive merger conflicts later on.
Software failure is expensive. Unleashing an application release that ruins existing user experience or introduces new risks would be counterproductive. Continuous testing ensures the right balance of software quality and speedy deployment is achieved.
In DevOps, software testing isn’t something left to one person or department. Rather, it’s everyone’s responsibility. Developers engineer quality into the code and then avail test data. Quality assurance and operations teams, in turn, configure test cases and the test environment.
Since tests must be executed quickly to avoid falling behind new changes being applied in development, the test process must be automated as much as possible.
Continuous delivery means changes to application code are automatically prepared for release into the live environment. This helps with application modernization, too. All code changes are deployed into a test environment before they are eventually applied to production.
The DevOps team always has a deployment-ready release that has successfully been taken through the standardized and automated test process. Release frequency will vary depending on goals, priority, and urgency. It may be as often as multiple releases per day or as seldom as one release per month or quarter.
Given the speed and number of releases, it’s imperative to have a solution in place that provides continuous monitoring to enable faster and better response to changing customer needs.
Continuous monitoring allows the DevOps team to track software performance and improve its stability. Problems are identified quickly, and root causes proactively investigated to prevent outages and downtime.
Monitoring starts during release development. The same monitoring tools that are applied in the live environment can be leveraged in development to pick up problems before they make their way into production.
