API Gateway for Microservices
Microservices provide fine-grained APIs based on client needs. Each client needs to interact with multiple services to collect relevant information. For example, a payment client needs to fetch data from several services such as product, customer, and billing.
API Gateway takes care of the external traffic of coordinating with different services. The API Gateway encapsulates the internal system architecture and provides an API that is tailored to each client.
The API Gateway is liable for Protocol translation, Composition, and Request Routing.

API Gateway Benefits
- Insulates the clients (internal structure of the application) from
Application partitioning into Microservices Location determination of service instances.
- Provides specific API to each client, reducing the number of round trips between the client and application.
- Simplifies the client by transferring logic for calling various services from the client to API gateway.
