Feature Showcase: Fan-Out Fan-In

Continuous Integration (CI) pipelines can be streamlined using the Fan-Out Fan-In pattern, which enhances speed and reliability by building the product once, testing it in parallel, and then deploying or releasing it if all tests pass. This method involves three stages: building a single artifact from the source code, running various tests such as unit, integration, and end-to-end tests in parallel to save time and ensure consistency, and finally consolidating these tests into a single release or deployment stage. By avoiding multiple rebuilds and ensuring all tests use the exact same artifact, this approach not only saves time but also simplifies debugging and maintains consistency across the pipeline, making it particularly effective for large projects requiring significant computing power.
