In software engineering, the terms front end and back end refer to the separation of concerns between the presentation layer (front end), and the data access layer (back end) of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the front end and the server is usually considered the back end, even when some presentation work is actually done on the server itself.

A resource management method, apparatus, and readable storage medium
This application discloses a resource management method, apparatus, and readable storage medium, relating to the field of electronic information. Compared to previous solutions, the resource management method provided in this application pre-adapts the front-end page of the resource pool to the cloud management platform. When a user logs in on the cloud management platform, the corresponding resource pool's front-end page is opened, and the instructions from the front-end page are forwarded to the resource pool's management platform back-end. Compared to the previous method of directly retrieving data from the corresponding resource pool using the cloud management platform's back-end management module, this solution avoids data and system transformation because both the front-end and back-end are the resource pool's own front-end and back-end. The logic is simpler, and since the front-end and back-end are adapted, advanced functions are not lost, resulting in higher applicability.
