Most application users are familiar with the front-end, or client-side, of an application, because that is the portion of the application users can see. But there is more than meets the eye for web and mobile applications. For most applications, all kinds of activities, including most user interactions, take place behind the scenes, in the back-end (“backend”), or server-side, of an application.
The backend of an application is the area where configuration of server, databases, interfaces and operating system occurs in order to power an application’s front-end. Many times, backend services are bundled together in a Backend-as-a-Service, or BaaS platform, but not always.
An applications’ backend operations may include user login, ordering and paying for items, messaging, search, location services, and any other function in which data may need to be sent, manipulated, or retrieved from a database.
Developers wishing to create applications with server-side interactions would likely need suitable Backend APIs.
