NAB decommissions 26-year-old Teradata platform

NAB has decommissioned its 26-year-old Teradata environment and migrated the data and use cases onto its new strategic data platform ‘Ada'.

Just over a year ago the bank officially launched 'Ada' as its new strategic data platform, deemed “chapter two” of NAB’s data journey.

Teradata was NAB’s oldest existing data platform, with a massive decommissioning process taking place over the past two years.

To migrate off it, NAB's team ingested 16 data sources into Ada, migrated 456 use cases and worked with hundreds of users across 12 business units.

“Decommissioning Teradata is a major milestone at NAB, and represents a significant step forward in our data strategy in migrating data and use cases to the Ada platform," executive for data delivery Andrea Jackson told iTnews.

“Hundreds of users were removed from almost every part of the bank including personal banking, business and private bank, corporate and institutional bank, enterprise operations, and others.

“By removing complex end-of-life legacy technology from our ecosystem, we’re able to streamline how and where data is stored and used for reporting and analytics, further reducing operational and security risk and providing a better user experience for our colleagues to use modern cloud technology.

“The program forms a key pillar of our data strategy as well as our broader technology simplification agenda."

Ada’s core is made up of data stack technology from Databricks, HVR/Fivetran, PowerBI, AWS and Azure.

“The Teradata migration and decommissioning program is the first large program to migrate use cases onto our strategic data platform ‘Ada’," Jackson said.

“In Ada’s first year, we’ve laid the foundations for many more use cases to be transitioned as we continue to modernise our data and technology infrastructure."
