GitLab Ultimate for IBM Z: Modern DevSecOps for mainframes

This post introduces GitLab Ultimate for IBM Z, which extends GitLab's CI/CD capabilities to the mainframe environment with native z/OS Runner support. It enables CI/CD pipelines to run directly on IBM z/OS, modernizes source code management by replacing legacy library managers with GitLab's repository system, and integrates with IBM Developer for z/OS Enterprise Edition for enhanced debugging and code scanning. This allows for unified development workflows across mainframe and distributed systems.
