Both big data analytics and mobile cloud applications are increasingly geographically distributed, relying upon services from multiple datacenters around the world. Yet, wide-area inter-datacenter links are costly to build and to upgrade, and inter-datacenter bandwidth is bound to become a scarce resource in the near future. Traditional data analytics need to first move all raw data to one datacenter before they can be processed, which adversely affect their performance and are bandwidth intensive. Real-time streaming analytics and interactive mobile cloud applications such as video conferencing and messaging, on the other hand, require low latencies. As such, there is a pressing need to manage and allocate inter-datacenter resources at a fine granularity to meet the diverse performance targets from both data analytics and mobile cloud applications.

大数据分析和移动的云应用程序在地理上的分布越来越多，依赖于来自世界各地多个服务中心的服务。然而，广域数据中心间链路的构建和升级成本很高，并且数据中心间带宽在不久的将来必然会成为稀缺资源。传统的数据分析需要首先将所有原始数据移动到一个数据中心，然后才能进行处理，这会对其性能产生不利影响，并且占用大量带宽。另一方面，实时流媒体分析和交互式移动的云应用程序（如视频会议和消息传递）需要较低的延迟。因此，迫切需要以细粒度管理和分配数据中心间资源，以满足数据分析和移动的云应用的不同性能目标。
