Episode 29 - Event Driven Architecture

In this episode of the Moonpig Tech Podcast, hosts Sam and Richard sit down with Principal Engineer Alexis Lowe to explore the intricacies of event-driven architecture (EDA) and how it's been implemented at Moonpig. Alexis dives deep into how events—such as order creation or user registration—are used to decouple systems, improve scalability, and boost resilience. The discussion touches on AWS tools like EventBridge, SQS, and DynamoDB, and explains concepts such as asynchronous messaging, eventual consistency, data projections, and idempotency.
