Dynamic Resource Allocation for Shared Data Centers Using Online Measurements

by Abhishek Chandra, Weibo Gong, Prashant Shenoy , 2003
"... Since web workloads are known to vary dynamically with time, in this paper, we argue that dynamic resource allocation techniques are necessary to provide guarantees to web applications running on shared data centers. To address this issue, we use a system architecture that combines online measure ..."

Dynamic Partitioning of the Cache Hierarchy in Shared Data Centers

by Gokul Soundararajan, Jin Chen, Mohamed A. Sharaf, Cristiana Amza , 2008
"... Due to the imperative need to reduce the management costs of large data centers, operators multiplex several concurrent database applications on a server farm connected to shared network attached storage. Determining and enforcing perapplication resource quotas in the resulting cache hierarchy, on t ..."

Efficient Management of Data Center Resources for Massively Multiplayer

by Online Games, Vlad Nae, Ru Iosup, Stefan Podlipnig, Radu Prodan, Dick Epema, Thomas Fahringer, Multiplayer Online Games
"... (MMOGs) can include millions of concurrent players spread across the world. To keep these highly-interactive virtual environments online, a MMOG operator may need to provision tens of thousands of computing resources from various data centers. Faced with large resource demand variability, and with m ..."

Abstract Memory Buddies: Exploiting Page Sharing for Server Consolidation in Virtualized Data Centers

by Timothy Wood, Gabriel Tarasuk-levin, Jim Cipar, Peter Desnoyers, Prashant Shenoy, Mark Corner, Emery Berger
"... Modern data centers increasingly employ virtualization in order to maximize resource utilization while reducing costs. With the advent of multi-core processors, memory has become the key limiting resource when running multiple virtual machines on a given server. In this paper, we argue for exploitin ..."
Abstract - Add to MetaCart
demonstrates that exploiting page sharing enables our system to increase the effective capacity of a data center by over 30%, while imposing a CPU and network overhead of less than 0.5% per server and scaling to data centers with up to a thousand servers. 1

GreenCloud: A Packetlevel Simulator of Energy-aware Cloud Computing Data Centers

by Dzmitry Kliazovich, Pascal Bouvry, Yury Audzevich, Samee Ullah Khan - in Proc. of the 53rd IEEE Global Communications Conference (Globecom
"... Abstract—Cloud computing data centers are becoming increasingly popular for the provisioning of computing resources. The cost and operating expenses of data centers have skyrocketed with the increase in computing capacity. Several governmental, industrial, and academic surveys indicate that the ener ..."

is designed to capture details of the energy consumed by data center components (servers, switches, and links) as well as packet-level communication patterns in realistic setups. The simulation results obtained for two-tier, three-tier, and three-tier high-speed data center architectures demonstrate

RESOURCE PROVISIONING FOR MULTI-TIER VIRTUALIZED SERVER APPLICATIONS

by Evangelia Kalyvianaki, Themistoklis Charalambous, Steven Hand
"... Virtualizing the x86-based data center creates a dynamic environment for server application deployment and resource sharing. Resource management in this environment is challenging as applications are under fluctuating workloads causing diverse resource demands across their tiers. Resource allocation ..."
