And the key lies in open source tools and communities.
In this blog, we’ll embark on an open-source odyssey, exploring the exciting world of open source mainframe tools and the vibrant communities that support them. We’ll delve into:
- The Need for Open Source in Mainframe DevOps
- Collaboration: Breaking Down Silos with Open Source Tools
- Community Projects: Powering Innovation Together
- Cost-Effective Solutions: Open Source Delivers Value
- Getting Started: Your Open Source Mainframe DevOps Toolkit
- The Future of Open Source in the Mainframe Realm
The Need for Open Source in Mainframe DevOps
Traditionally, mainframe development relied on proprietary tools and processes. While these solutions ensured stability, they often lacked the agility and flexibility demanded by modern applications. DevOps thrives on collaboration and automation, two areas where open source tools shine.
Open source offers a plethora of benefits for mainframe DevOps:
- Cost-Effectiveness: Ditch expensive vendor lock-in and explore free or low-cost open source alternatives.
- Flexibility: Open source tools are often modular and customizable, allowing you to tailor them to your specific needs.
- Innovation: The open-source community thrives on continuous development, fostering a constant stream of new ideas and features.
- Security: Open source code allows for transparency and collaboration on security fixes, promoting a more secure environment.
Collaboration: Breaking Down Silos with Open Source Tools
DevOps preaches the importance of breaking down silos between development and operations. Open source tools play a pivotal role in facilitating this collaboration. Let’s explore some key areas:
- Version Control: Tools like Git provide a central repository for code, allowing developers and operations to track changes, collaborate on bug fixes, and manage deployments seamlessly.
- Continuous Integration/Continuous Delivery (CI/CD): Open source CI/CD tools like Jenkins automate the build, test, and deployment process, ensuring consistency and reducing errors.
- Automation: Open source scripting languages like Python and Bash enable developers to automate repetitive tasks, freeing up valuable time for innovation.
- Monitoring and Logging: Open source monitoring tools like Zabbix and Grafana provide real-time insights into system health, allowing operations teams to proactively identify and address issues.
Community Projects: Powering Innovation Together
The open-source community is the beating heart of the open-source movement. These passionate individuals and organizations contribute their time and expertise to develop and maintain invaluable tools. Here are some prominent open-source projects for mainframe DevOps:
- Open Mainframe Project (OMP): A Linux Foundation initiative fostering collaboration on open source tools for the mainframe. Key projects include Zowe (API for interacting with z/OS) and OpenSUSE for z Systems.
- Ansible: A powerful automation tool that can easily manage and configure mainframe systems alongside other infrastructure.
- Apache Kafka: This distributed streaming platform enables real-time data integration between mainframes and other systems.
Cost-Effective Solutions: Open Source Delivers Value
Let’s face it, mainframe environments can be expensive to maintain. Open source tools offer a compelling cost-effective alternative. Here’s how:
- Reduced Licensing Costs: Open source tools eliminate the need for expensive vendor licenses, freeing up resources for other IT initiatives.
- Lower Development Costs: Leverage the power of readily available open source libraries and frameworks to accelerate development and reduce costs.
- Increased ROI: Invest in open source tools and empower your teams to be more productive and agile, leading to a faster return on investment.
Getting Started: Your Open Source Mainframe DevOps Toolkit
Ready to embark on your open-source mainframe DevOps journey? Here’s a basic toolkit to get you started:
- Git: The industry-standard version control system for tracking changes and managing code collaboratively.
- Jenkins: A popular open source CI/CD tool that automates the build, test, and deployment process.
- Zowe: This OMP project provides a modern API for interacting with z/OS, allowing developers to leverage familiar tools and languages.
- Ansible: A powerful automation tool that can configure and manage mainframe systems alongside other infrastructure.
Remember, this is just a starting point. As you explore further, you’ll discover a vast array of open-source tools that cater to specific needs.
The Future of Open Source in the Mainframe Realm
The future of open source in the mainframe landscape is brimming with possibilities. Here are some key trends to watch:
- Continued Innovation: Expect the open-source community to deliver a constant stream of new tools and enhancements, further blurring the lines between traditional and modern development approaches.
- Security Focus: As security threats become more sophisticated, open source projects will prioritize security features and best practices, fostering a more secure mainframe environment.
- Integration with Cloud: Open source tools will bridge the gap between mainframes and the cloud, enabling seamless data exchange and hybrid deployments.
- Growing Adoption: As the benefits of open source become undeniable, we’ll see a continued rise in adoption across the mainframe community. This will further fuel innovation and collaboration within the open-source ecosystem.

Hi,
great article.
Proper experience learns that, also for mainframers, change hurts.
Moving to GIT is allready a big step.
Moving to Groovy, Ansible, Python,.. is even a bigger step.
Most mainframers know and still like JCL.
Why not continue with JCL for compile and deploy tasks.
Ikan with Kobee offers such a GIT based CI/CD solution using JCL.
