API Gateway bridge solution

The API Gateway bridge solution supports deployment scenarios where the API Gateway and its authorized applications are deployed in separate environments. These environments can include multi-tenant cloud, single-tenant cloud, or on-premises installations.

The bridge solution provides a secure method for authorized applications to access APIs across network boundaries while maintaining authentication, authorization, and user identity controls. It allows two API Gateway instances to communicate with each other while preserving user identity and supporting user impersonation.

The bridge solution applies to scenarios such as:

• An authorized application running on-premises that needs to access APIs hosted in a multi-tenant environment
• A single-tenant deployment that must invoke APIs available only in the multi-tenant Infor cloud
• Backend services that require secure access to APIs in another environment while retaining user context
• Hybrid architectures supported during cloud migration projects
