National Bank of Australia (NAB) has expanded its multi-cloud strategy by bringing Google Cloud into its ecosystem alongside Microsoft Azure and Amazon Web Services (AWS).

The move means that almost 90 per cent of its applications are now running on cloud.

When the bank started its transformation journey in 2018, just two per cent of the company’s apps were on cloud.

Since moving to the cloud, the bank has reported an 89 per cent reduction in critical and high outages, as well as the delivery of “significant improvement” in the time taken to deploy new products and features for its customers.

NBA says it is the first major bank in the southern hemisphere to scale across the world’s largest cloud providers.

NAB also announced it has extended its relationship with Microsoft through to the end of 2031.
AWS is NAB’s primary cloud provider for core applications, having been partnered with the platform for over a decade.

Steve Day, NAB executive enterprise technology, said the multi-cloud milestone marks a “strategic leap”, adding that it will unlock the unique strengths of the three global technology leaders to drive better outcomes for NAB’s customers.

“We’ve been on a multi-year transformation, moving from an on-premises environment to an insourced, cloud-first model to deliver better availability and experiences for our customers,” he added. “What this means is that our architecture is now built to run anywhere, portable and scalable.

“Most importantly for our customers, our systems are now significantly more reliable for them.”
