Adding a Service Registry
Removing a Service Registry
API Gateway user interface provides capability to add and configure service registries and communicate these changes across nodes in the cluster. An API Gateway administrator can add and remove service registries.
Overview
A service registry is essentially a catalog of services. Applications that expose services can register their services with one or more service registries. Applications that need to consume a service look up a service registry and obtain the address of an application server that provides the service. Using service registries with API Gateway adds resilience, scalability, and security to the application stack.
API Gateway uses service registries in the following ways:
*You can publish APIs defined in API Gateway to service registries. This enables other applications to use the service registry to dynamically locate an API Gateway instance that provides that API.
*You can set an API Gateway route to a service registry endpoint. This enables API Gateway to use the service registry to dynamically locate an application instance and route the request to it.
Service Registries supported by API Gateway
API Gateway currently supports the following service registries.
*Eureka
Eureka is a REST-based service for locating services for the purpose of load balancing and failover of middle-tier servers. It has been primarily designed for applications in the AWS cloud.
*Service Consul
Service Consul is a tool for discovering and configuring services in IT infrastructure.
