GFT's high level of technical expertise enabled us to migrate a critical component of a Cobol-based host application to a modern, cloud-enabled infrastructure. In addition, GFT ensured the transfer of know-how to the Deka team as well as the necessary performance optimisations in the job flow.”
El reto
Transformation of the host-based application landscape while reducing operating costs
- Modernise a key part of the existing core banking application by connecting the sales partners to the depot system with only minimal code changes
- Replatform as an initial step in the transformation of business-critical applications with continuous cooperation with all existing peripheral systems and databases
- Reduction of running costs for infrastructure and software by reducing MIPS, especially at reporting date processing (month-end/year-end)
Additional requirements for the migrated application:
- Operability without emulation in the target environment
- Ongoing maintenance by existing developers
Compromiso
Modernisation of the Cobol-based host application by building a modern target environment, migrating and commissioning relevant software
GFT managed the end-to-end migration, including:
- Definition of a modern, container-based target architecture and support client during deployment
- Migration of the selected application modules and transfer of host-specific elements, such as sequential files, into platform-compatible solutions. Part of the migration were the job nets of the migrated application itself, as well as their embedding into the existing job net for all further host applications.
- Documentation at all levels - from conception to operating manual - and coaching of employees
Beneficio
Increased performance, boosted efficiency and reduced costs
- Despite the necessary additional data exchange between host and Unix system up to 90 minutes faster processing of the processes
- Reduction of previously occurring additional MIPS costs for key date processing at the end of the month and year
