Optimizing Cost for Online Social Networks on Geo – Distributed Clouds, Geo-distributed clouds provide an intriguing platform to deploy online social network (OSN) services. 

 

We carry out extensive experiments with a large-scale real-world Twitter trace over 10 geo-distributed clouds all across the US. Our results show that, while always ensuring the QoS and the data availability as required, cosplay can reduce much more one-time cost than the state-of-the-art methods,  and it can also significantly reduce the accumulative cost when continuously evaluated over 48 months, with OSN dynamics comparable to real-world cases.

 

INTERNET services today are experiencing two remarkable changes. One is the unprecedented popularity of online social networks (OSNs), where users build social relationships and create and share contents with one another.

 The other is the rise of clouds. Often spanning multiple geographic locations, clouds provide an important platform for deploying distributed online services.
