Engage DevOps Accelerators

DevOps is a culture of collaboration by Development, Quality, and Operations to address issues in all three spaces. A Continuous Integration/Continuous Delivery pipeline is an automated process to quickly move applications from development through testing to deployment. Pega Platform includes tools to support DevOps, keeps an open platform, provides hooks and services based on standards, and supports most popular tools.

 

What

Use DevOps practices such as continuous integration and continuous delivery to quickly move application changes from development through testing to deployment on your production system. Use Pega Platform tools and common third-party tools to implement DevOps.

 

Why

Pega Platform developers use Agile practices to create applications and commit the changes into branches in a shared development environment. Automated and manual testing provides rapid feedback to developers so that they can improve the application.

 

How

Follow these best practices to optimize the development process:

  • Leverage multiple built-on applications to develop and process smaller component applications. Smaller applications move through the pipeline faster and are easier to develop, test, and maintain.
  • Create one Pega Platform instance as a source environment that acts as a single source of truth for the application. This introduces stability into the developer environment and ensures that a problem in one developer environment does not affect other environments.
  • Use Pega Platform developer tools, for example:
    • The rule compare feature allows you to see the differences between two versions of a specific rule.
    • The rule form search tool allows you to find a specific rule in your application.
  • Follow branch-based development practices:
    • Developers can work on a shared development environment or local environments.
    • Content in branches migrates from the development environments to merge into the source environment.
    • Create an archive by exporting and storing backup versions of each branch in a separate location in the application repository. If a corrupted system state requires you to restore the source environment to a previous known good application version, the branches can be down-merged to reapply the changes in those branches that were lost as part of the restore.
    • Use PegaUnit tests to create limited regression tests for each developer, which work independently of UI changes.
    • Later on, PegaUnit tests should be replaced with a comprehensive regression test suite such as Selenium.
  • Ensure that the work on a ruleset is reviewed and that the changes are validated. Lock every complete and validated ruleset.
  • Regularly synchronize the development environments with the source environment.
