Learn how message queues and pub/sub decouple services, why at-least-once delivery demands idempotent consumers, how backpressure and dead-letter queues protect the system, and when microservices are worth the complexity — with a sequenceDiagram of async order processing.

Async work between services without one tripping the other. Point-to-point vs pub/sub, the three delivery guarantees and what they cost, dead letter queues, and how to pick between Kafka, RabbitMQ, SQS, and friends.

Dive into Apache Kafka, a powerful distributed streaming platform designed for high-throughput, fault-tolerant data pipelines. Understand its core components, architecture, and how it enables real-time data processing for modern applications.
