The unique contributions of API gateways for operationalizing microservices in a beneficial fashion are growing as days pass. The main features of an API gateway are the following:
- Adds flexibility: API gateways are supposed to hide internal concerns from external clients. An API gateway decouples external APIs from internal microservice APIs. This abstraction facilitates the addition, replacement, displacement, and substitution of advanced microservice implementations in place of legacy ones. The APIs of internal microservices can be changed without affecting the requesting microservices. Services can be freshly registered and referenced in a service registry or repository. The service discovery of newer services can be smooth and error free. Services can be versioned.
