NAB retires its Tableau environment

NAB has decommissioned its 11-year-old Tableau environment as part of a continued move to a new data platform that it calls Ada.

The bank’s chief data and analytics officer Christian Nelissen marked the decommissioning with a LinkedIn post, saying that the enterprise instance of Tableau had been turned off.

At its height, the instance supported over 11,000 reports and 4000 users.

Nelissen wrote that these reports were either migrated to PowerBI or switched off entirely.

It’s the second major decommissioning of a data system by NAB and follows the bank’s retirement of its 26-year-old Teradata environment.

Teradata was turned off at the end of 2023.

It later emerged that the bank live-streamed the end of that platform to “thousands” of people, as a way to formally mark the end of an era and a new beginning for the bank’s data infrastructure.

It’s understood there wasn’t the same fanfare around the Tableau decommissioning.

A NAB spokesperson declined to comment.

Ada is considered “chapter two” for the bank and its data journey and is built on a data stack comprising technology from Databricks, HVR Fivetran, PowerBI, AWS and Azure.
