The paper presents an architecture for resource management in hosting centers, focusing on energy efficiency and dynamic resource provisioning. The system, called Muse, is designed to manage server resources for co-hosted services, adaptively allocate resources based on load, and respond to power supply disruptions or thermal events by degrading service according to Service Level Agreements (SLAs). Muse uses an economic approach where services "bid" for resources based on performance, and a greedy resource allocation algorithm (MSRP) adjusts resource prices to balance supply and demand. The system also includes a reconfigurable server switching infrastructure to direct request traffic. Experimental results show that Muse can reduce server energy usage by 29% or more for typical web workloads, demonstrating its effectiveness in managing energy and server resources in hosting centers.The paper presents an architecture for resource management in hosting centers, focusing on energy efficiency and dynamic resource provisioning.
