What serves as the interface for sending microservice requests in Teamcenter?

The Active Workspace Gateway functions as the interface for sending microservice requests in Teamcenter. It acts as a structured communication conduit between the Active Workspace and various backend services, including those that are built around microservices architecture. This gateway not only facilitates requests and responses but also handles authentication, ensuring secure interactions while providing the necessary service orchestration.

Other options may involve components that play a role in the management or execution of microservices, but they do not specifically serve the purpose of handling the communication between the client-side of Teamcenter and microservices. This distinction is crucial to understand the architecture of Teamcenter and how it enables effective interaction with microservices.
