Application Modernization and Migration to AWS Cloud

Providing enterprises the capability to transform their mainframe legacy applications and migrate to the AWS Cloud

Deloitte’s Application Modernization and Migration to AWS Cloud consulting offer, powered by innoWake™, offers a comprehensive solution for enterprises' mainframe migration and modernization journeys. The approach Deloitte has developed helps enterprises migrate legacy off the mainframe to AWS, while minimizing execution risk.

Deloitte's automated, tools-based approach supports legacy technology written in a variety of programming languages, such as common business-oriented language (COBOL), Natural, Job Control Language (JCL), Programming Language One (PL/1), CA Gen, and others. Deloitte's innoWake™ solution helps customers migrate legacy applications and associated technology stacks to the AWS Cloud. This critical step of being off the mainframe unlocks possibilities for further efficient modernization and capability enhancements.

  • How it works
  • Deloitte’s Application Modernization and Migration to AWS Cloud consulting offer begins with the creation of an implementation roadmap based on customers' priorities, focusing on core system improvements rather than reinventing what already works. The innoWake™ solution not only converts legacy systems to a contemporary technology platform, but also addresses key areas that can be enhanced after core systems are modernized while enhancing and leveraging your current IT investments.

    Once the transformation is completed, the code base is in a modern language, the data structures are normalized, and the user experience employs web-enabled screens. IT no longer has to support older mainframes, which helps customers save time, resources, and significant costs, and be more responsive to the business. Additionally, the migrated system is compatible with agile development and DevOps processes. At this point, the transformation enables the adoption of various modernization opportunities such as mobility, advanced analytics, and cybersecurity.

    What does a transformed application look like? Your end users may not notice significant changes. Deloitte's transformation insures that applications have the same functionality, look, and feel, but are dressed up in a modern web interface.

    Developers will understand that the underlying code base has been transformed, yet the transformed code will interact with migrated data exactly as it did in the legacy system. The modern code mirrors legacy code. This is critical, as it enables developers to continue maintaining the applications as well as allowing new Java developers to quickly learn how to maintain transformed legacy applications.
