Abtract: The explosive growth of demands on cloud computing imposes a heavy burden on computation, storage, and communication in geo-distributed data centers, hence incurring considerable operational expenditure. This talks will present a couple of representative cases that we studied recently on cost optimization for big data services in geo-distributed data centers.
