1. Growth In the Cloud
Global Data Center Traffic is projected to more
than triple between 2015 and 2020, with cloud
traffic within data centers forecast to nearly
quadruple during that period.

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 Traffic Originate?
By 2020, traffic between
data centers and end
users will reach 2.2 ZB
annually (14% of total
data center traffic).
1.4 ZB (9%) will come
from traffic between
data centers, such as
replication and
interdatabase links.
But the vast majority of data center traffic, 11.7 ZB (77%), will
still be coming from within the data center, such as storage,
production, development, and authentication traffic.
