How to design resilient infrastructure for modern banking
Blog post from Tyk
Resilient infrastructure design is crucial for modern banking, as emphasized by experts at the LEAP 2026 conference, including Lalitha Kagithapu from First American and Caleb Cole from Wings Credit Union. They underscore the importance of incorporating resiliency into the design process to ensure robust API foundations and maintain critical member services even amidst disruptions. At First American, key components include network resiliency, standardized authentication, and an infrastructure-as-code approach, supported by tools like Tyk as an API gateway for scaling and high availability. Wings Credit Union focuses on metrics such as system uptime, recovery time, and vendor SLAs, alongside regular testing to ensure recovery capabilities. Resiliency design also involves addressing common failure points like limited visibility, inconsistent authentication, and uncontrolled dependency chains, using observability and circuit breaking. By leveraging best frameworks and collaborating with business, IT, and security teams, financial institutions can map critical processes to infrastructure and test for threats, ensuring technical failures do not translate into business failures.
