Explanation
The concept of shares within a cloud environment is used to mitigate and control the request for resource allocations from customers that the environment may not have the current capability to allow. Shares work by prioritizing hosts within a cloud environment through a weighting system that is defined by the cloud provider.
When periods of high utilization and allocation are reached, the system automatically uses scoring of each host based on its share value to determine which hosts get access to the limited resources still available. The higher the value a particular host has, the more resources it will be allowed to utilize.
