Distributed Communication Patterns

Fifteen animated sections: the third outcome and partial failure, synchronous vs asynchronous, REST/gRPC/GraphQL, service discovery and load balancing, timeouts and deadline propagation, retries with jitter, idempotency keys, circuit breakers and bulkheads, queues and topics, delivery guarantees and ordering, dead letter queues and backpressure, the dual write and the outbox, sagas, polling, server-sent events and WebSockets, and webhooks and async request-reply.
