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.
