Commonwealth Bank Modernizes Core Unlocking Data

Commonwealth Bank completed its migration from an on-premises SAP R/3 mainframe to SAP S/4 on AWS in October last year, unlocking about 90% of its customer, account and transactional data. The move cut infrastructure costs by 30%, improved performance by 30% and enabled real-time eventing tested at about 5,000 transactions per second, feeding Amazon SageMaker and Bedrock to pursue deep personalisation and agentic AI.
