An Australian bank Kick-Starts Digital Transformation with NashTech

Australian bank Kick-Starts Digital Transformation


NashTech implemented a cloud solution that enabled the bank to seamlessly integrate its various systems with its data platform, enable the use of the new CRM, create the loan originator capabilities and replace its core banking system with an agile foundation.

Founded in 2016, it is Australia’s first challenger bank for small-to-medium enterprises (SMEs), and in November 2021 was the first fully licensed Australian bank to list on the Australian Securities Exchange (ASX) in 25 years. Its founders, who are highly experienced bankers, recognised that SME businesses were receiving neither the funding nor the service they needed to grow and prosper. In response, this Australian Bank aims to bring back the craft of relationship banking, and its relationship bankers focus on spending quality time with SME customers.


The bank’s journey is rapidly evolving as it works on its internal systems to make it easier to observe and manage increasing data as new customers sign up. As a key part of its evolution, the company began to create a “service fabric” made up of point-to-point integrations that were becoming increasingly hard to deal with in light of the company’s plans to build and launch a new CRM and loan originator system. With the help of Apache Kafka® and NashTech Cloud solution, the bank was able to seamlessly integrate its various systems with its data platform to enable the use of the new CRM, create the loan originator capabilities, and replace its core banking system with an agile foundation that will serve the company as it digitally transforms and continues to disrupt the banking world.


From an architectural perspective, they had Kafka on their radar from the very beginning. “We consume managed services at the bank; we don’t own our IT, so we knew we had to figure out how to connect everything together,” said the Head of Cloud Service Architecture.

“This is when the idea of a ‘service fabric’ came up. While we weren’t in a position to operate our own Kafka when we started, we knew that was the end goal—to send, via event streaming, the messages within the enterprise between the different connected managed services.”

In 2020, the bank embarked on a large program to uplift its systems to support the continued growth of the business.

“We were basically doing a heart and lung transplant as well as a spinal cord surgery in the bank,” said Niko Bielovich, General Manager of Service Management. “We were changing 15 different systems on the go-live weekend.”

The company implemented its first NashTech release in 2021 in parallel with introducing a new CRM and loan origination system. They now operate NashTech Cloud as a private cluster with managed AWS connectors. It has connections between its CRM, loan origination system, and core banking system to bidirectionally exchange data between customers’ loan account creations and loan balances.

A key ingredient to making this environment work was Itoc, an AWS advanced consulting partner and leading cloud-managed services provider, which they leveraged to facilitate communication and data transfer between their CRM and core banking systems. They engaged Itoc to design, develop, and implement the integration solution built using NashTech Cloud and AWS. The solution has become an essential integration component across the Bank services, significantly reducing time to synchronise both systems from hours to seconds.

Although in its current implementation, the NashTech setup functions more as a message bus than an event streaming platform. The bank plans to leverage ksqlDB more in the future as it moves toward the use of more real-time streaming data. “We’re trying to do as much as we can with ksqlDB because it’s so easy to deploy in a managed environment,” Piefke said.

The bank team is now creating patterns for managed connectors to stream events (such as DynamoDB) that will serve as the persistence layer for APIs and microservices to increase the use of the managed platform that comes with NashTech Cloud.

“From this point forward, I see NashTech and event streaming being part of whatever we do,” Piefke said. “For example, NashTech will play a major part in improving our customers’ digital, online banking experience. It’s also beneficial to have the data platform to tap into for all the events flowing through NashTech as well.”



A more agile, consistent, and unified tech stack. “Before NashTech, we had point-to-point integrations,” Piefke said.“All those bits and pieces were developed by different teams and partners and targeted to a specific case. Each pipeline had its own implementation. NashTech brings a more consistent approach. Our commissioning and decommissioning activities will be quick with NashTech, and we’ll have much better agility moving forward.”

Better data availability and time to market. “Our finance and FinOps teams have faster access to data from creation. NashTech has improved our data availability,” Piefke explained. “While there is some overhead when getting started on publishing events, once the events are on the platform, they’re easy to consume and produce. NashTech improves time to market and we’re expecting a shorter release time to production going forward.”

Better support for microservices. “A great benefit of NashTech as an event streaming system is, of course, that it provides a complete publish-subscribe environment, the ability to replay, and the ability to create a data mesh and have applications tap straight into materialized views,” Piefke said. “So, it’s really a great support for microservices. In the long run, we want to make NashTech the single source of truth for all of our services.”

What’s next

The bank has a pipeline of new and exciting event streaming projects over the next 12 months. They now have a data platform that uses event streaming for near-real-time data processing. They are looking into using NashTech to enable integrations with external partners, via APIs or sharing a public cluster directly.

“NashTech is a strategic platform for us. With every project we look at, we now think about how we use NashTech to move things around and join things together.”
