Commonwealth Bank of Australia (CommBank) has renewed its partnership with Amazon Web Services (AWS), signing a five-year strategic partnership.

With this move, the bank said it will leverage AWS's cloud-native designs and workforce capabilities to further simplify its technology environment, with a focus on accelerating the adoption of artificial intelligence (AI) and improving security when delivering new customer experiences.

CommBank added that the technology has been instrumental in the creation of the CommBiz genAI messaging service, a new service designed to reimagine banking for tens of thousands of business banking customers.

The genAI messaging service aims to enable business banking customers to make payments faster. The tool facilitates this by pulling information from more than 80 different CommBiz user guides and FAQs and other support pages to quickly provide relevant information using natural language.

“Leveraging the bank's DevOps (Development Operations) hosting platform, as well as the group's Generative.AI platform and Guardrails service, the product went from concept to production in just six weeks,” the bank said in a statement.

AWS will also continue to provide CommBank engineers with access to tools and opportunities to boost their skills in the cloud through co-creation of new solutions, training and certification, such as AWS Cloud Certification.

This follows the launch of CommBank's AI Factory in September 2024, created to help accelerate the adoption of AI across the bank and enable engineers to test and develop AI solutions and fine-tune large AI language models at faster speeds.

CommsBank began its journey into the cloud with AWS more than ten years ago. Since then, it has migrated several key platforms and applications, including Netbank, CommSec and MUREX, from on-premise environments to AWS.

CommBank chief technology officer Rodrigo Castillo said: “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.”
