How Nationwide increased resiliency and availability of digital services
The Speed Layer cache stores and structures data so sophisticated systems can be connected easily
Although Nationwide has invested significantly in technology over the past decade, it worked hard to maintain and protect the complex systems that powered their digital offerings.
The British financial institution’s incredible growth and savvy adoption of digital channels put even more stress on traditional data systems, increasing the imperative to scale and add resilience for the extra demand. With success came an increased urgency to shore up the technology landscape.
The business impact
The results are astonishing. Speed Layer microservices take just 7 milliseconds response time. It takes less than 45 minutes daily for Speed Layer to reconcile all the data (300m records) within MongoDB and Kafka topics against the “systems of record.” Advanced engineering and performance testing practices saved around £4 million in infrastructure costs.
First and foremost, Speed Layer introduced a new data layer that enabled Nationwide to create a robust ecosystem of digital services that are always online and resilient to outages. The solution’s two-speed IT strategic architecture lets Nationwide evolve customer-facing digital capabilities at high speeds while decoupling legacy systems that roll out new functionality at a slower pace.
Furthermore, by standardising data access for channels, Speed Layer empowers the building society to launch more digital, customer-focused products while harnessing data for strategic business insights. Speed Layer is an enabler for innovation through data enrichment techniques and event stream processing to drive future customer products such as real-time notifications, personalised banking products, fraud monitoring and many more potential use cases.
