Melania's software development team uses an approach that creates many discrete software objects and then binds them together using APIs. What term best describes this architecture?

This is an example of a microservices architecture. Each of the component microservices performs a discrete task and then communicates with other microservices using APIs. This might be accomplished using function-as-a-service (FaaS) cloud computing, containerization, and/or virtualization, but there is no indication whether those services are being used in the scenario.
