Dynamic Routing with Service Discovery
Implement dynamic routing rules that automatically adapt to changes in your microservice landscape via service discovery.
What is Dynamic Routing?
In a microservices architecture, services often scale up and down, and their network locations can change. Hardcoding routes with specific IP addresses or ports becomes impractical and brittle.
Dynamic routing allows your API Gateway to automatically discover and route requests to available service instances without manual configuration updates.
Service Discovery Recap
Recall that service discovery (e.g., using Eureka or Consul) allows microservices to register themselves with a central registry.
- Services announce their presence and network location.
- Clients (like our Gateway) can query this registry to find available service instances by their logical name.
