The growth of cloud-based services in consumer and business applications during the past five years has been spectacular. Projections are that this trajectory will continue during the next five years. By 2019 mobile network traffic is forecasted to increase tenfold. Half of this increase will be in video services, and an additional 10 percent will be in social networking applications. At the same time, business cloud computing services are expected to increase at a 40 percent average annual rate. By 2019 there will be 60 percent more data centers in the world’s metropolitan areas than there are today, and data center interconnect volumes will increase by more than 400 percent.
