Capgemini’s Mainframe Modernization to AWS

Financial Services firms can get started on their digital transformation journey by identifying and migrating workloads to the cloud. The benefits of cloud are well known, including decreased IT costs while allowing organizations the flexibility to scale their processes up or down depending on changing demand. However, incumbents saddled with legacy systems may find this task daunting.

Capgemini’s Mainframe to AWS solution is a scalable, robust and highly secure solution that distinguishes the critical mainframe components from the obsolete and/or redundant components that can be unloaded before migration. Those that are retained are configured as business function-based modules that can be regenerated as microservices, driving cloud-native development.

The solution is powered by our state-of-the-art CAP360 tool suite, an industry-leading legacy code analysis platform that assesses, componentizes and prioritizes based on feasibility, criticality, target availability and business benefit.

This holistic solution modernizes mainframe applications and addresses key business pain areas like agility, maintainability, elasticity, scalability, interoperability between systems and high operational expenditures.

Our solution is designed to intricately weave together all the crucial stages of the cloud journey into a controlled, cost-effective and risk-demystified transformation roadmap. The phases of the transformation journey bring:

  • Automated Inventory Analysis at a granular code level
  • Componentization of business functions using Domain-Driven Framework
  • Reverse Engineering to preserve the important business rules
  • Building robust interim state integration architecture
  • Agile and DevOps Methodology
  • Enabling AWS Native Development of microservices
