Microservices Communication Patterns

Microservices are small, independent services that work together. Think of them as tiny, specialized apps.

A big challenge in microservices is how they talk to each other. They need to share data and coordinate actions without becoming tightly coupled.

There are two main ways services communicate:

• Synchronous: Service A calls Service B and waits for a reply. Like a phone call.
• Asynchronous: Service A sends a message and doesn't wait. Service B picks it up later. Like sending an email.

Asynchronous communication is often preferred for microservices because it:

• Reduces dependencies
• Improves fault tolerance
• Allows services to scale independently
