I'm writing an article that discusses the advantages of using the API Gateway pattern combined with a sidecar within the same microservices environment. These two patterns are often thought of as an either/or decision because they overlap. In the article I propose using both in some situations. What is a good descriptive term for such an architecture? One option is to call it "hybrid architecture", but that already describes an on-prem, off-prem (cloud) thing. Another is "integrated architecture", but it's a broader concept in the world of software architecture. I thought of "composite architecture", but this may also be confused with the composite GoF design pattern.

Any architects out there know if this combo, API Gateway + sidecar, has a name?
