Microservice Communication Patterns

Microservice communication patterns are the ways different small software components, or "microservices," share information to work together smoothly. Think of them as methods for these services to "talk"—such as sending direct messages, publishing updates for others to receive, or requesting data on demand. Common patterns include synchronous calls like APIs, where services wait for a response, and asynchronous messaging, where messages are sent without expecting immediate replies. These patterns ensure that each microservice can operate independently while still collaborating effectively within the overall system.
