DrbCF: A Differentiated Ratio-Based Approach to Job Scheduling in Cloud Federation
Phuong-Duy Nguyen, Nam Thoai · 2016
The utilization and flexibility of using resource embrace each organization builds its own private cloud. Cloud Federation is a recent paradigm that helps deal with both physical resources under-utilization and resource limitation in their local infrastructure. Due to the management separation, we are interested in self-sufficiency approach in discovering and matchmaking to establish the federation with other clouds. We leverage event-based design helps communicate over sites to enable negotiate scheduling between among providers. We propose decentralized broker supporting differentiated ratio-base job scheduling (DrbCF) to manage send/receive workload. Our evaluation shows the ability to accept new small capacity member and improve overall federation throughput with the differentiated rate approximately 14-16%. DrbCF is a useful tool supporting the differentiated capacity sites as well as the dynamic of interconnect structure under cloud circumstance.
