摘 要：
Online social networks are organised around users who have certain expectations from their network provider, such as low latency access to both their own data and their friends’ data, often very large, e.g. videos, pictures etc. Replication of data can be used to meet these requirements and geo-distributed cloud services with virtually unlimited capabilities are suitable for large scale data storage. However, social network service providers often have a limited monetary capital to store every piece of data everywhere to minimise users’ data access latency. Therefore, it is crucial to have optimised data placement to fulfil the users’ acceptable latency requirement while having the minimum cost for social network providers. In this seminar, we address key problems including how to find the optimal number of replicas, how to optimally place the datasets and how to distribute the requests to different datacentres.
