What Is Mainframe DevOps?
Mainframe applications and databases are tried and tested, and operate at enormous scale and efficiency. At the same time, they can bring huge costs of maintenance and use and create challenges for enterprise organizations looking to leverage existing systems and data for new applications.
With the ability to deploy Linux and containerization solutions within a logical partition (LPAR) on a mainframe, the door is now open to build mainframe-hybrid applications, and port existing DevOps tooling into the mainframe environment. This makes it possible to leverage CI/CD practices to create new applications leveraging mainframe business logic and data, and the modernization of legacy mainframe code.
The result: Organizations can utilize new technologies and approaches without incurring the cost of revamping existing applications from scratch. By using old languages alongside new, and utilizing API/microservices-based systems, large organizations can continue to use old apps while building new apps on mainframe infrastructure.
