We consider the scenario where a cloud service provider (CSP) operates multiple geo-distributed datacenters to provide Internet-scale service. Our objective is to minimize the total electricity and bandwidth cost by jointly optimizing electricity procurement from wholesale markets and geographical load balancing (GLB), i.e., dynamically routing workloads to locations with cheaper electricity. Under...
Geographical load balancing (GLB) is a promising technique to reduce power cost for cloud service providers (CSPs). To fully exploit the potential of GLB, Camacho et al. [1] advocate broker-assisted GLB where CSPs first bid in deregulated electricity markets and then balance their workloads accordingly. In this paper, we further explore along this line and propose the idea of Second Chance, which...
