CBA chief data officer Andrew McMullan says the bank is on the point of shifting all its data platforms to the Cloud, an essential step in its AI ambitiions. CBA supplied.

Commonwealth Bank (CBA) is in the final stages of migrating all its data platforms to Amazon Web Services (AWS) Cloud — nine months ahead of schedule — further cementing its leadership in technology and artificial intelligence (AI) among Australian banks.

CBA was the first bank in the region to collaborate with AWS on an AI Factory to develop generative AI in September 2024. Since then, it has been working with AWS to embed AI across its engineering functions.

Speaking at an AWS event this week, CBA’s chief data and analytics officer, Andrew McMullan, confirmed the migration would make AWS the bank’s primary data platform provider for AI and data operations.

“We go live in May,” he said. “The initial plan was 18 months to migrate all of our data platforms. We will deliver that in under nine.”
