Inter-service Communication
Implement patterns for effective communication between microservices, including event-based and request-response mechanisms.
Microservices Need to Talk
Microservices are designed to be independent, but they often need to collaborate to complete complex tasks. This means they must communicate with each other!
In this lesson, we'll explore the main patterns for how your NestJS microservices can send messages and share data effectively.
Sync vs. Async Communication
Understanding the difference between synchronous and asynchronous communication is crucial for microservices:
- Synchronous: The sender waits for an immediate reply. It's like a direct phone call where you expect an answer right away.
- Asynchronous: The sender doesn't wait for a reply. It's like sending an email – you send it and continue with other tasks, expecting a reply later (or not at all).
Both patterns have distinct use cases in a distributed system.
