This template presents the architecture of an application. On the left, there are icons representing a "Web Application" and a "Mobile Application". These connect to the "Deployment" section in the upper - middle, which includes "API Authentication & Authorization", "Booking API", and "User API". The APIs communicate with a "Database" on the right. The system also has a connection to "Error Logs" for tracking issues. Additionally, there is a "Background Workflows" section at the bottom, encompassing functions like "Email", "SMS", "Webhooks", "Reminders", and "In - app Notif.", which can communicate with third - party services. This diagram provides a clear overview of how different components of the application interact, facilitating development, maintenance, and understanding of the overall system structure.
