๐ Enhanced Key Takeaways
- โขCommonwealth Bank of Australia (CBA) has migrated over 10 petabytes of data and 61,000 data pipelines to Amazon Web Services (AWS), completing what it claims is one of the largest and fastest data migrations in the Southern Hemisphere.
- โขThe migration extends to CBA's core banking system, making it the first major Australian retail bank to fully transition its core operations to the public cloud, replacing its legacy mainframe infrastructure.
- โขCBA currently leverages AI to make approximately 55 million decisions daily, utilizing over 2,000 AI models that process around 157 billion data points.
- โขThe bank has developed an internal multi-agent AI platform named 'Lumos' to automate and accelerate application modernization, boosting the modernization velocity from 10 applications per year to 20-30 applications per quarter.
- โขCBA has established an 'AI Factory' powered by Amazon EC2 P5 Instances, providing high-performance compute capacity to accelerate generative AI innovation and enable engineers to safely test and develop AI solutions.
๐ ๏ธ Technical Deep Dive
- Cloud Provider: Amazon Web Services (AWS) is CBA's preferred cloud provider.
- Data Migration Scale: Over 10 petabytes of data and 61,000 on-premise data pipelines were migrated.
- Core Banking System: Migrated from mainframe infrastructure to AWS-managed data centers.
- Data Lake: CBA's data lake, previously hosted on Snowflake within AWS, has been brought into closer proximity with its core systems on AWS to improve AI performance and efficiency.
- Data Architecture: An AWS-based data mesh ecosystem, branded as "CommBank.data," has been established, featuring a federated data architecture that enables self-service data access for 40 lines of business.
- AI Platforms/Tools:
- Lumos: An internal multi-agent AI platform used for application modernization, integrating with AWS services such as Bedrock, ECS, and OpenSearch.
- AI Factory: Powered by Amazon EC2 P5 Instances, this factory provides high-performance computing for fine-tuning large language models (LLMs) and developing AI solutions.
- CommBiz Gen AI: An AI-powered messaging service built on the bank's DevOps Hosting platform and Group Generative.AI Platform, utilizing Amazon Bedrock Knowledge Bases, Claude 3, Cohere LLMs, and Amazon OpenSearch.
- Partnerships: Collaborations with H2O.ai for a customer engagement engine and real-time generative AI for fraud prevention, and with Anthropic for generative AI capabilities.
- AWS DevOps Agent: Explored for accelerating root cause analysis in cloud operations.
- Migration Process: The data platform migration, which began in mid-2024, was completed in 9 months with HCLTech as a partner, leveraging AI and generative AI for code transformation, error checking, and 229,000 tests with 100% accuracy reconciliation. The core banking migration was an 18-month project involving partners like SAP, SAP Fioneer, Accenture, AWS, and Red Hat.
- Regulatory Compliance: CBA worked closely with the Australian Prudential Regulation Authority (APRA) to ensure all banking data remains in Australian-based AWS facilities.
