What is Matrix builds and why does it matter in DevOps?

Matrix builds refer to the practice of running multiple builds or tests in parallel, allowing different combinations of configurations, environments, or dependencies to be tested simultaneously. This is particularly useful in continuous integration and continuous deployment (CI/CD) pipelines, where you want to ensure that your code works across various systems and setups.

In a DevOps environment, matrix builds matter because they enhance the efficiency of the development and testing process. By running parallel builds, teams can identify issues quickly, leading to faster feedback and iteration cycles. This helps maintain code quality, reduce integration problems, and ultimately speed up the delivery of software.
