Friendship based storage allocation for online social networks cloud computing

Online Social Networks (OSN) is one of the booming technologies started in the last decade with significant influence in people internet usage and daily life. Billions of individuals and organizations can share their status, news, photos, videos and files in a free open online world wide community. During the last few years, social networks became a key player in the media sector, advertisement, politics and online gaming. Social networks are a special kind of networks; where the users access not only their own data but their friends´ data as well. So each user may access many datacenters in few minutes while browsing his/her friends´ feeds., Cloud computing is the new era of datacenter that offers IT as a service. In this paper, we propose a storage allocation mechanism in cloud computing that considers the OSN characteristics such as the friendship matrix and users´ locations in order to utilize cloud computing usage for social networks. The proposed algorithm minimizes the average users´ data access latency in OSN.
