Building Event-Driven Multi-Region Serverless Apps with AWS EventBridge Global Endpoints

Building applications that are both resilient and globally available has become a core requirement—especially for serverless workloads where infrastructure is abstracted away but uptime remains critical. AWS EventBridge Global Endpoints introduce a powerful mechanism for routing events intelligently across multiple regions, enabling seamless failover and high availability in the face of outages or regional disruptions. This guide explores how to build a robust event-driven, serverless application that operates across AWS regions, using EventBridge Global Endpoints to ensure continuity and disaster recovery. We will walk through a real-world use case—processing e-commerce orders—and demonstrate how to replicate events, maintain state, and automate failover using a combination of EventBridge, Lambda, DynamoDB, and Route 53. Whether you’re preparing for disaster scenarios or aiming for global scalability, this guide will help you design and deploy serverless systems that can withstand regional failures without compromising performance or reliability.
