What is API Gateway Pattern in Microservices Architecture? What Problem Does it Solve?

The API Gateway can help in managing authentication, request routing, load balancing, and caching in Microservices architecture.

Hello friends, if you are learning Microservices architecture then you must have come across patterns like SAGA, CQRS, API Gateway etc. These are common Microservices patterns which are used to solve common problems which comes on Microservices architecture.

In the past, I have shared Microservices Interview Questions as well as essential Microservices design principles and patterns and in this tutorial we will deep dive into API Gateway pattern.

The API Gateway Pattern is a design pattern used in microservices architecture to provide a single entry point for clients to access multiple microservices. In this pattern, a gateway service acts as a facade for all incoming requests from clients and forwards them to the appropriate microservices.

The API Gateway is responsible for handling tasks such as authentication, request routing, load balancing, and caching. By providing a single entry point, the API Gateway simplifies the client’s interaction with the microservices system, as clients don’t need to know the…
