7.9 zettabytes

There’s no denying that the digital universe has
experienced unprecedented growth. Here’s a look
at some of the factors fueling this explosion and
what the next five years may hold in store.

WHAT’S CONTRIBUTING TO THIS EXPLOSION?
A plethora of new, Internet-enabled digital devices
are a major force. Every device that comes online
creates more data moving across networks.

While PCs are still a mainstay, mobile devices
are rapidly outpacing them. Other connected devices
such as televisions and Blu-ray players will continue
to add to the data stream as rapidly as they are adopted.

By the end
of the year,
there will be more
networked devices
than people
on earth.
One-fifth of
Internet video
traffic will come from
TVs, handsets, and
other non-PC devices.
Internet traffic
from wireless
devices will surpass
the volume of
traffic from
wired devices.
The majority of big data contributors originate in North America
and Europe. As other global regions come online more fully,
data generation is expected to increase exponentially.
INFORMATION LOAD
It’s easy to see that individuals are increasingly
generating vast amounts of digital content from
photos and video to tweets and documents.
What’s less obvious is the growth of “shadow data,”
such as account access journals and web search histories,
that‘s constantly generated around user activity.

Although over 70% of the digital universe is created, captured or replicated
by individuals — consumers and desk and information workers toiling far away from
the data center — enterprises have responsibility or liability for 85%.
