CommBank & AWS team to deliver global cloud and AI capabilities
By Gloria Mathias
Australia’s CommBank has entered a five-year strategic collaboration with Amazon Web Services (AWS) to continue as the bank’s preferred cloud provider. This agreement marks the next step in CommBank’s technology journey to become tomorrow’s bank today for customers.
By rearchitecting a percentage of our workloads onto AWS and using cloud-native designs, we are further simplifying the bank’s technology environment. This helps accelerate AI adoption and improves the delivery of new customer experiences faster and more securely.
The agreement was central to the creation of the CommBiz Gen AI-powered messaging service, designed to reimagine banking for tens of thousands of Business Banking customers. Leveraging the bank’s Development Operations (DevOps) Hosting platform, the Group Generative.AI Platform and the Guardrails Service, the product went from idea to production in just six weeks.
This expanded collaboration with AWS reinforces CommBank’s commitment to leveraging the exceptional talent of its engineers. The bank recognises that continuous investment in its skills is critical to maintaining its position in delivering digital customer experiences.
CommBank Chief Technology Officer Rodrigo Castillo said, “As customer adoption of digital banking continues to grow, we’re harnessing AI and cloud to deliver faster, safer and more personalised digital banking services. AI is enabling new experiences for customers delivered faster than before, providing a frictionless experience to build and release new AI-powered products and features for our customers in a safe, responsible way.”
Jamie Simon, Director of Financial Services, AWS Australia and New Zealand, commented, “The CommBank and AWS relationship spans more than a decade, and we are excited to expand upon it as we support their digital transformation through this next phase of cloud adoption. Together, we will simplify and standardise their technology foundations on the most secure and resilient cloud platform, enabling faster experimentation and adoption of AI and other key technologies.
“As the cloud provider of choice to some of the largest banks, insurers and financial institutions in Australia, we understand the local demands of a heavily regulated industry for a highly secure, resilient, flexible, and scalable platform to enhance the performance and availability of their critical operations. AWS offers this, as well as a proven track record that helps them meet their regulatory obligations and delivers significant value to their millions of customers across Australia.”
