Migration from Symphony to ArmoniK: GMD's Journey

Context of the migration

GMD (Global Markets Division) at Crédit Agricole Corporate and Investment Bank (CA-CIB) relied heavily on IBM Symphony for their grid computing needs. The existing system faced significant challenges in meeting growing computational demands and evolving regulatory requirements. These issues led to inefficiencies, high operational costs, and limited scalability. To address these problems, GMD needed a more robust and flexible solution that could scale efficiently and reduce costs. Modernizing their IT environment also addressed another key objective for GMD: attracting and retaining top IT talent.

Unlike Equity IT, which adopted a phased approach, GMD opted for a more accelerated, one-off approach with parallel runs. This decision was driven by the critical nature of GMD's operations, which required minimal downtime and the ability to maintain continuous service throughout the transition. The parallel run strategy allowed GMD to run the old and new systems simultaneously, ensuring a seamless migration without disrupting ongoing operations.

What Aneo did

Aneo, with its extensive experience in high-performance computing and cloud solutions, was engaged to facilitate the migration. The project began with a thorough assessment of GMD's current infrastructure and computational requirements. Aneo proposed a comprehensive migration plan to transition from Symphony to ArmoniK, utilizing AWS for cloud scalability. This plan included updating the codebase to modern standards compatible with cloud environments and setting up a Linux-based grid infrastructure. Aneo worked closely with GMD to ensure a seamless transition, providing continuous support and expertise throughout the process.
