National Australia Bank (NAB) has adopted Google Cloud as part of a multi-cloud strategy that enterprise technology executive Steve Day says has delivered an “89% reduction in critical and high outages”, and made the bank’s systems “significantly more reliable” for customers.
The move adds Google Cloud to NAB’s existing cloud ecosystem, which includes Microsoft Azure, first deployed in 2020 with an agreement now extended to the end of 2031, and Amazon Web Services (AWS), which the bank initially adopted as its primary cloud provider in 2013.
Day explains how this multi-year transformation strategy has led to nearly 90% of the bank’s applications being moved to the cloud, up from just 2% in 2018. “What this means is that our architecture is now built to run anywhere, portable and scalable,” he says. “Most importantly for our customers, our systems are now significantly more reliable for them.”
However, NAB is not alone in the race to adopt cloud technology. Direct competitor Bendigo and Adelaide Bank completed a migration of its digital banking system to Google Cloud more than two years ago, while fellow ‘Big Four’ bank Westpac is also in the midst of a five-year cloud transformation with AWS, which first commenced in 2023.
More recent developments from across the region’s banking sector include Commonwealth Bank of Australia (CBA), which confirmed with FinTech Futures last week the successful migration of its SAP core banking platform to AWS.
NAB has notably sought to bolster its transformation strategy through a corporate structuring announced this week, which saw the promotion of long-time bank executive Shane Conway to group executive of transformation, effective 1 December 2025. According to a statement, Conway will “continue to be accountable for the ongoing delivery of NAB’s technology modernisation and simplification agenda” through the new position.
