The design and implementation of approving system on private IaaS cloud platform

To make the allocation of hardware resources more reasonable and flexible on private infrastructure as a service cloud platform in enterprises, approving system described in this paper provides an efficient solution. Each user has a basic quota. If users need to get more resources, the reason must be given to apply. According to the performance of the eventually practice on OpenStack, this system can prevent users from allocating more hardware resources than they need, and save the hardware resources. We implemented the approving system on OpenStack, and the resource of server was saved.
