WSO2 API Manager Microgateway is a lightweight message processor for APIs. The Microgateway is used for message security, transport security, routing, and other common API Management related quality of services. It can process incoming and outgoing messages while collecting information required for usage metering and throttling capabilities. The Microgateway natively supports scaling in highly decentralized environments including microservice architecture. Immutable, ephemeral Microgateway fits microservice architecture well. The Microgateway is capable of operating in lockdown environments such as IoT devices, since connectivity from the Microgateway to the API Management system is not mandatory.
The following topics explain further details about the API Microgateway, its architecture and capabilities, and how to configure and deploy it:
