System Design Examples

Now that we have covered how the pattern works, here is where it is used in practice.

Use Cases

First, when should you use the Service Discovery pattern? It suits large distributed systems. Use it when services must call each other and their locations keep changing.

Microservices Architectures

One prime example is a system designed around microservices. In a microservices architecture, the system is divided into small, independent services that each perform a specific function. These services need to communicate with each other to achieve the system's overall functionality.
