DekaBank replatforms with GFT

A modernised core application

GFT is modernising DekaBank's Cobol-based host application by re-platforming it onto a modern, cloud-enabled infrastructure and enabling the benefits of modern technologies, environments and architectures.

Performance enhancement

90 minutes earlier data provision at the end of the month

Cost efficiency

Permanently lower operating costs through reduced

Know-How

Knowledge transfer to the bank team

Client

DekaBank

DekaBank is the securities services provider of the German Savings Banks Finance Group. Together with its subsidiaries it forms Deka Group, which provides retail and institutional clients access to a wide range of investment products and services. DekaBank is firmly anchored in the Sparkassen-Finanzgruppe and designs its portfolio of products and services to meet the requirements of its shareholders and sales partners in the securities business.

Challenge

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

Engagement

Modernisation of the Cobol-based host application by building a modern target environment, migrating and commissioning relevant software

This visual represents GFT and Anubex's collaborative approach to automated application modernisation, ensuring seamless migration and enhanced performance for financial institutions.

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

Benefit

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

“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.”
