Inter-Service Communication Patterns

In a microservices architecture, your application is broken into many small, independent services. For these services to work together and deliver a complete user experience, they must communicate with each other.

This communication is called inter-service communication. It's how one service requests data or triggers actions in another.

Synchronous communication is like a direct phone call. When Service A needs data from Service B, it sends a request and then waits for Service B to respond before continuing its own work.

• Request-Response Model: Service A waits for a response from Service B.
• Blocking: Service A is blocked (cannot do other work) until the response arrives.
