AWS Mainframe Modernization

Discover how AWS Mainframe Modernization helps you modernize as well as migrate your legacy mainframe applications to AWS managed runtime environments. This solution not only transitions applications from on-premises systems to the cloud but also updates their runtime environments, ensuring optimal performance and scalability.

AWS Mainframe Modernization provides a comprehensive toolkit for planning and executing your migration and modernization strategies. It enables you to analyze existing mainframe applications, update or develop new code using languages such as COBOL or PL/I, and set up CI/CD pipelines for continuous integration and delivery. Depending on your client's needs, you can choose between automated refactoring for modernization or a straightforward replatforming method.

Refactoring

Refactoring modernizes your legacy application artifacts so they can seamlessly run in modern cloud environments. This process involves code and data conversion and often requires rewriting portions of your application to optimize it for the cloud.

The AWS Blueprints service automates much of this refactoring process, offering end-to-end support for migrating and modernizing your mainframe applications. The refactoring process includes:

• Evaluating your application inventory
• Assessing system dependencies
• Automatically transforming legacy code
• Capturing and managing various test scenarios

Replatforming

Replatforming is another modernization approach where you transfer your mainframe application to a new computing platform without modifying its source code. This method allows a quick migration to the cloud while preserving the existing codebase.

If your primary objective is to move your applications to the cloud swiftly, then replatforming is the ideal strategy. However, if you also need to modernize your application architecture and code, refactoring would be the better choice.
