The use of API gateways in a microservices architecture provides a really interesting way of approaching the microservices integration problem, while also following one of the patterns of application integration through the use of federated gateways. So, let’s take a look at how the API gateways help us in the process of microservices integration.
An API gateway inside the microservices-based application acts as central point through which the microservices can interact with the other microservices present in the infrastructure. This API gateway provides the following characteristics:
- Restricted exposure of APIs: The API gateway provides the functionality of exposing only a restricted set of APIs from the backend microservices, hence limiting what functionality is exposed. Along with this, the API gateway can...
