Synopsis

More and more banking institutions consider public cloud and especially Amazon Web Services (AWS) as an option to answer their increasing compute needs. Indeed, AWS offers virtually unlimited resources available almost immediately upon request and paid only when used. AWS also gives access new technologies such as the latest \Intel high performance processors or the more exotic Gaudi accelerator from Habana Labs~(an \Intel Company). These new processors are a way to reduce both the costs and the carbon footprint of computation.

This book provides insight into the migration process for banking institutions from Microsoft Windows to Linux on Amazon Web Services (AWS). The migration is divided into two parts: codebase migration from Windows to Linux and AWS migration with three architectural options to consider: lift and shift, AWS-native, and ArmoniK, a kubernetes-based grid scheduler. The report details the technical difficulties that may arise during the migration process such as performance gains, bugs, and numerical discrepancies, as well as organizational challenges that need to be addressed.

This book also provides a concrete example of a successful migration in a French Bank, highlighting the best practices and lessons learned. The example showcases the migration of two grids from on-premise Windows to Linux on AWS, providing insight into the migration process and the challenges that may arise.
