Which layer in API-led connectivity handles the orchestration of services?

The Process Layer is responsible for the orchestration of services in an API-led connectivity architecture. This layer acts as a mediator and coordinator between the Experience Layer and the System Layer. Its primary function is to implement business logic, manage the interactions between different services, and ensure that the data flows smoothly between the various components.

In contrast, the Experience Layer focuses on the user experience, providing APIs tailored for specific use cases that interact with end-users or client applications. The Data Layer, on the other hand, is concerned with managing and accessing data from various sources, enabling data storage and retrieval processes. The System Layer serves as a foundation, representing the backend systems that provide core functionalities and data.

Thus, the Process Layer is uniquely positioned to manage the flow of information, transforming, aggregating, and directing requests to the appropriate services, making it essential for orchestrating multiple services effectively in the overall architecture.
