API Gateway is required to manage and monitor microservice landscapes. However, the volume of communication among microservices can cause network latency and security issues for API Gateways in such environments. The microservice architecture pattern has therefore created a need for lightweight gateways to supplement API Gateway and prevent bottlenecks.

Microgateways are lightweight gateways that enable microservices to communicate with each other directly, without involving API Gateway. Microgateways enforce policies that perform authentication, traffic monitoring, and traffic management. You can enforce protection policies on Microgateway to ensure a secure communication channel among microservices.

Microgateways pull assets such as APIs, applications, policies, and administrative settings such as SSL and fault configurations from API Gateway, and push back runtime analytics information collected while monitoring API requests and responses to API Gateway.
