Multiserver System Configuration Scheme for Profit Maximization

As a promising and valuable IT commercial model, Cloud computing has been paid considerable attention by academia and industry [1], which makes the configuration of storage, computing, and communication resources a common commodity for pay-as-you-go management. Thanks to the rapid development of virtualization techniques, an increasing number of users can expediently receive cloud services, which spawns a group of excellent cloud service providers (e.g., Ali Cloud [2], Google [3], and Amazon [4]). The increasing number and variety of cloud service providers also promote the sustainable development of cloud computing. The pursuit of profit maximization is a natural goal for service providers. To realize this goal, cloud service providers are supposed to fully understand the relationship between the economics of cloud services and the system resource management of the cloud platform (also called the multiserver system), especially in a geographically distributed multiserver system, and serve the intermittent cloud service requests.
