Understanding best practices for DevOps-based development workflows

Version:

In a DevOps workflow, the most important best practice for application developers to adopt is continuous integration. Continuous integration is the process by which development changes to an application are integrated as frequently as possible, at least once a day and preferably multiple times a day, every time developers complete a meaningful unit of work.

To enforce best practices when developing an application and to ensure that application changes are of high quality, developers should use Pega Platform features such as branches. Before merging branches and integrating changes, developers should also verify that the application meets guardrail compliance and that unit tests pass. If the validation of development changes passes, the branch is merged into the application ruleset.

However, if validation fails, then the merge is rejected, and developers should be notified so that they can address the failure and resubmit their changes. The feedback cycle of validating and integrating development changes should be as fast as possible, preferably 15 minutes or less, because it increases productivity in the following ways:

  • Developers do not spend unnecessary time to see that their changes are valid, which enables them to make incremental changes.
  • Incremental changes tend to be easier to validate, debug, and integrate.
  • Other developers spend reduced time coordinating making changes and can be confident that they are building on validated functionality.

How you implement best practices for continuous integration depends on whether you have a smaller scale development with one or two scrum teams using a shared development environment or multiple distributed development teams. See the following topics for more information:
