In the third
annual Cisco Global
Cloud Index (2012 – 2017) issued
today, Cisco forecasts that global cloud traffic, the fastest growing
component of data center traffic, is expected to grow 4.5-fold – a
35 percent combined annual growth rate (CAGR) – from 1.2 zettabytes
of annual traffic in 2012 to 5.3 zettabytes by 2017. Overall global
data center traffic will grow threefold and reach a total of 7.7
zettabytes annually by 2017.
Approximately 17
percent of data center traffic will be fueled by end users accessing
clouds for web surfing, video streaming, collaboration and connected
devices, all of which contribute to the Internet of Everything, which
is the networked connection of people, data, process and things.
Other data center
traffic is not caused directly by end users, but by data centers and
cloud-computing workloads used in activities that are virtually
invisible to individuals. For the period 2012–2017, Cisco forecasts
that 7 percent of data center traffic will be generated between data
centers, primarily driven by data replication and software/system
updates. An additional 76 percent of data center traffic will stay
within the data center and will be largely generated by storage,
production and development data in a virtualized environment.
From a regional
perspective, the Cisco Global Cloud Index predicts that through 2017,
the Middle East and Africa will have the highest cloud traffic growth
rate (57 percent CAGR), followed by Asia Pacific (43 percent CAGR)
and Central and Eastern Europe (36 percent CAGR).
Key Highlights/Findings:
- Global data center traffic growth will increase
threefold by 2017 - Cisco forecasts that global data
center traffic will triple from 2.6 zettabytes in 2012 to 7.7
zettabytes annually in 2017, representing a 25 percent CAGR.
- Global cloud traffic will grow faster than overall
global data center traffic - The transition to cloud
services is driving global cloud traffic at a growth rate greater
than global data center traffic. Global data center traffic will
grow threefold (a 25 percent CAGR) from 2012 to 2017, while global
cloud traffic will grow 4.5-fold (a 35 percent CAGR) over the same
period.
- Global cloud traffic will account for more than
two-thirds of total global data center traffic -
Globally, cloud traffic will grow from 46 percent of total data
center traffic (98 exabytes per month or 1.2 zettabytes annually) of
total data center traffic in 2012 to 69 percent of total data center
traffic (443 exabytes per month or 5.3 zettabytes annually) of total
data center traffic by 2017.
- Cloud traffic growth by region: The Middle East and
Africa will have the highest cloud traffic growth rate from 2012 to
2017 - The Cisco Global Cloud Index now includes
regional forecast data for cloud traffic growth.
o
In 2012, North America generated the most cloud traffic (469
exabytes annually), followed by Asia Pacific (319 exabytes annually)
and Western Europe (225 exabytes annually).
o
By 2017, North America will generate the most cloud traffic
(1.886 zettabytes annually), followed by Asia Pacific (1.876
zettabytes annually) and Western Europe (770 exabytes annually).
- Workload transitions: From 2012 to 2017, data center
workloads will grow 2.3-fold; cloud workloads will grow 3.7-fold
- In 2012, 39 percent of workloads were processed in the
cloud, with 61 percent being handled in a traditional data center.
- 2014 will be the first year when the majority of workloads
shift to the cloud; 51 percent of all workloads will be processed
in the cloud versus 49 percent in the traditional IT space.
- By 2017, nearly two-thirds or 63 percent of workloads will
be processed by cloud data centers; 37 percent will be processed by
traditional data centers.
- The ratio of workloads to nonvirtualized cloud servers will
grow from 6.5 in 2012 to 16.7 by 2017. Comparatively, the ratio of
workloads to nonvirtualized traditional data center servers will
grow from 1.7 in 2012 to 2.3 by 2017.
- Workload growth by region: By 2017, North America will
have processed the most cloud workloads, followed by Asia Pacific
- The Cisco Global Cloud Index now includes regional forecast
data for workload growth.
- In 2012, North America had the most cloud workloads (15.2
million or 47 percent of global cloud workloads), followed by Asia
Pacific, which had 6.8 million or 21 percent of global workloads in
2012.
- In 2012, North America had the most cloud workloads (15.2
million or 47 percent of global cloud workloads), followed by Asia
Pacific, which had 6.8 million or 21 percent of global workloads in
2012.
o
By 2017, North America will process the most cloud workloads
(48.2 million or 41 percent of global cloud workloads), followed by
Asia Pacific, which will have 36.5 million or 31 percent of global
workloads by 2017.
o
From 2012 to 2017, the Middle East and Africa region is
expected to have the highest cloud workload growth rate (45 percent
CAGR), followed by Asia Pacific (40 percent CAGR) and Central and
Eastern Europe (31 percent CAGR).
o
Globally, except in the Middle East and Africa and Asia
Pacific, traditional data center workloads (rather than cloud
workloads) will grow at a low-single-digit CAGR from 2012 to 2017.
Key APAC
Highlights/Findings:
- Asia Pacific, data center traffic will grow 3.6-fold by
2017, at a CAGR of 29% from 2012 to 2017- Data center
traffic will reach 2.7 Zettabytes per year (228 Exabytes per month)
in 2017, up from 772 Exabytes per year (64 Exabytes per month) in
2012.
- Asia Pacific cloud data center traffic will grow
5.9-fold by 2017, at a CAGR of 43% from 2012 to 2017 faster than
overall data center traffic - Cloud data center
traffic will represent 68% of total data center traffic by 2017,
compared to 41% in 2012. Consumer will represent 79% of cloud data
center traffic by 2017, compared to 74% in 2012.
- Asia Pacific leads in the number of subscribers
throughout the forecast period due to the region’s large
population.
