Serverless Edge Pattern with Amazon CloudFront Functions in the Banking Industry: Enhancing Performance and Security

This paper examines the serverless edge pattern using Amazon CloudFront Functions in the U.S. banking industry, focusing on its role in improving performance and security. By executing lightweight JavaScript functions at CloudFront’s edge locations, banks can enhance content delivery, reduce latency, and bolster security through authentication and header validation. Benefits include serverless support, layered network strategies, and multi-language flexibility, demonstrated via U.S.-specific implementations. Challenges such as execution constraints, integration complexity, and regulatory compliance are addressed with practical solutions. Incorporating trends up to December 2024, including surging digital adoption and cyber threats, this study illustrates how CloudFront Functions enable U.S. banks to provide secure, efficient services in a competitive digital landscape.
