Abstract

Geo-distributed clouds provide an intriguing platformto deploy online social network (OSN) services. To leveragethe potential of clouds, a major concern of OSN providers isoptimizing the monetary cost spent in using cloud resources whileconsidering other important requirements, including providingsatisfactory quality of service (QoS) and data availability to OSNusers. In this paper, we study the problem of cost optimizationfor the dynamic OSN on multiple geo-distributed clouds overconsecutive time periods while meeting predefined QoS and dataavailability requirements. We model the cost, the QoS, as wellas the data availability of the OSN, formulate the problem, anddesign an algorithm named. We carry out extensiveexperiments with a large-scale real-world Twitter trace over10 geo-distributed clouds all across the US. Our results showthat, while always ensuring the QoS and the data availability asrequired, can reduce much more one-time cost than thestate-of-the-art methods, and it can also significantly reduce theaccumulative cost when continuously evaluated over 48 months,with OSN dynamics comparable to real-world cases.
