Microsoft Azure provides the default API management platform tool call API Management, which provides rich features to manage and monitor APIs in the Azure environment. However, for the hybrid on-prem/off-prem cloud environment and multi-cloud environment, the organization may want to simplify the API communication to make it more efficient, flexible on executing external workflow, or plugin a security module to manage APIs hosted on-premises or across clouds.
The self-hosted gateway feature extended from Azure API Management enables those hybrid and multi-cloud API management requirements and allows the organization to customize the API implementation, integration, communication, routing management, monitoring, traffic, and security controls in the cloud environment. It supports APIs hosted in either on-prem or off-prem across different cloud instances.
