Gateway Routing Design Pattern Tutorial with Example for Software Programmer

In this video we will learn about Gateway Routing design pattern. This is the 4th design principle in Integration design patterns category for microservices.

Gateway Routing pattern is Route requests to multiple microservices with exposing a single endpoint. This pattern is useful when we want to expose multiple services on a single endpoint and route them to internal backend microservices based on the request.

The pattern is useful expose multiple services on a single endpoint and route the request to an appropriate service based on logic. Route requests to multiple services or multiple service instances using a single endpoint.
client application only needs to know about a single endpoint and communicate with a single endpoint.

• Expose multiple services on a single endpoint and route to the appropriate service based on the request.
• Expose multiple instances of the same service on a single endpoint for load balancing or availability purposes.
• Expose differing versions of the same service on a single endpoint and route traffic across the different versions.

** Usage of this Design Pattern **
1. Use this pattern whenever you have multiple disparate services.
2. Use this pattern whenever you have multiple instances of the same service.
3. Use this pattern whenever you have multiple versions of the same service.

** Advantages of this Design Pattern **
1. Gateway Routing pattern provides single endpoint for consumer to consume.
2. Gateway Routing pattern allows single endpoint for the multiple versions of same service.
3. Gateway Routing pattern allows single endpoint for the multiple services
