However, the cloud abstraction offers the illusion of ubiquitous resources which can mislead users to believe that \details" of cloud implementation such as location of cloud datacenters with respect to users does not matter. Such location-agnosticism can adversely affect performance when computing on data that is distributed or partitioned across several datacenters. We present several solutions for efficiently computing on such data.
