Decoupling Services with Events β
In a monolith, components call each other in-memory. In a distributed microservices environment, services communicate across networks. Relying entirely on HTTP/REST makes services tightly coupled and prone to cascading timeouts. We use Event-Driven Architectures with message brokers (like RabbitMQ, Apache Kafka, or AWS SQS) to decouple components.
gRPC & Protobuf: For fast synchronous communication, gRPC replaces HTTP/JSON with HTTP/2 and binary Protocol Buffers, cutting packet size and execution overhead by up to 10x.
