Crafted with EdrawMax, this image is a software architecture diagram detailing the structure of an API service. It outlines the layers of technology from front-end user interfaces down to back-end processing. At the top, we see "REST APIs" and "UI/UX" elements that interact with users, supported by services like "Azure frontdoor" and a "shipzero frontend app." The "API {rest}" is central, linking the user-facing components with back-end functionalities such as "shipzero service," authentication systems like "JWT auth," and various databases represented by SQL icons. This diagram is essential for developers and engineers to visualize and understand how different parts of the system integrate to provide seamless service to the users.
