Growth In the

CloudBy 2018, 76% of global data center tra�c will come from cloud services and applications.

1 zettabyte (ZB) is equal to sextillion bytes, or a trillion gigabytes.

Global data center traffic is projected to nearly triple between 2013 and 2018, with data center traffic specifically in the cloud forecast to quadruple during that period.

How Do These Traffic Types Contribute to the Overall Data Center Traffic?

0.7 ZB (8%) will come from traffic between data centers, such as replication and interdatabase links.

But the vast majority of data center traffic, 6.4 ZB (75%), will still be coming from within the data center, such as storage, production, development, and authentication traffic.

By 2018, tra c between datacenters and end users will reach 1.5 ZB annually (17% of total data center tra�c).

Some traffic flows between the data center and end users, some traffic flows between data centers, and some traffic stays within the data center.

Where Does This Data Center Tra�c Originate?
