100 Days of System Design Questions challenges

Design an event-driven architecture for facilitating communication between microservices in a distributed system. The architecture should support decoupled and asynchronous communication patterns, allowing services to react to events and trigger actions accordingly. Consider factors such as event sourcing, message brokers, event-driven patterns, and event-driven data synchronization in your design. Discuss how you would define and propagate events across services, including event schemas, event routing, and event delivery guarantees. Additionally, address how you would ensure event reliability, fault tolerance, and scalability to handle varying workloads. Provide insights into the technologies, messaging protocols, and architectural patterns you would employ to implement this event-driven architecture effectively.
