Adjusting Resource Quota
In order to prevent resource abuse, the platform limits the quota of each service resource and also the number and capacity of resources available to users, for example, how many physical servers and EVS disks can users create.
If the current resource quota cannot meet your business needs, you can apply for a quota increase.
