GitLab & IBM launch platform to modernise mainframe DevOps
GitLab and IBM have introduced GitLab Ultimate for IBM Z, a solution designed to address the distinct challenges faced by mainframe software development teams.
The new offering targets long-standing issues within enterprise mainframe environments, where teams have traditionally operated with outdated tools. This situation has often resulted in slow delivery cycles, heightened security risks, and increased operational costs. By providing native continuous integration and continuous deployment (CI/CD) pipelines on IBM z/OS, unified source code management, and direct integration with IBM Developer for Z, the companies aim to place mainframe developers on a more equal footing with their counterparts working in cloud-native settings.
Mainframe development challenges
Many organisations running mission-critical workloads on IBM Z systems encounter significant hurdles using conventional DevSecOps tools, which are not tailored to the specifics of mainframe development. While cloud-native teams benefit from automated, collaborative environments and robust pipelines, mainframe teams have historically had to rely on legacy software, workaround solutions, and manual processes such as SSH file transfers. These practices introduce security and compliance concerns and make audits more complex.
Such workarounds become particularly problematic in highly regulated sectors, where maintaining strict audit trails and minimising vulnerabilities are essential. The continued use of separate, legacy development toolchains results in higher licensing and maintenance costs, compared to more modern alternatives, while also leading to slower delivery cycles and making it harder for enterprises to attract new technical talent.
Katie Norton, Research Manager, DevSecOps and Software Supply Chain Security at IDC, commented on the significance of the new solution:
"GitLab Ultimate for IBM Z represents an important step in addressing a long-standing industry challenge. IDC research shows that mainframe developers often work with legacy tooling that contributes to delivery inefficiencies and makes it harder to attract new talent. With this offering, modern DevSecOps capabilities and unified workflows are brought directly to the mainframe. This empowers developers to work more collaboratively and efficiently, while helping organisations accelerate innovation and integrate mainframe development into broader digital transformation strategies."
Modernisation and integration
The GitLab and IBM partnership intends to foster true modernisation by providing a unified development platform. This allows mainframe, cloud-native, web, and mobile teams to collaborate and share knowledge across environments, reducing technical silos. Teams are able to incrementally modernise without major business disruption, adopting more contemporary workflows while legacy systems continue to operate.
As organisations look towards hybrid cloud architectures, the integrated approach is intended to support applications that need to span both mainframe and cloud environments, giving development teams more options for deployment and collaboration.
Solution details
GitLab Ultimate for IBM Z delivers native z/OS Runner support, which enables CI/CD pipeline execution directly on mainframes, reducing the need for remote connections and associated security risks. The platform incorporates GitLab's source code management system, replacing legacy library managers and providing version control and searchable repositories, which may help organisations lower licensing fees and operational overhead.
Integration with IBM Developer for z/OS Enterprise Edition brings features such as dependency-based builds, automated code scanning, and debugging, designed to improve both the quality and security of releases. The offering also aims to give teams end-to-end visibility across mainframe and distributed activities, which is intended to support automated workflows and help retain development talent.
Capabilities for enterprise teams
By combining GitLab's DevSecOps platform with IBM's experience in mainframes, GitLab Ultimate for IBM Z is positioned as a solution for enterprises seeking to bridge the gap between legacy systems and newer, cloud-native environments. The goal is to facilitate modern development practices directly within mainframe settings, promoting collaboration, efficiency, and cost-effectiveness for enterprise users.
