SAN JOSE, Calif., Feb. 05, 2018
(GLOBE NEWSWIRE) -- Today, Cisco released the seventh
annual Cisco® Global Cloud Index (2016-2021). The updated
report focuses on data center virtualization and cloud computing,
which have become fundamental elements in transforming how many
business and consumer network services are delivered.
According to the study, both consumer and business
applications are contributing to the growing dominance of cloud
services over the Internet. For consumers, streaming video, social
networking, and Internet search are among the most popular cloud
applications. For business users, enterprise resource planning
(ERP), collaboration, analytics, and other digital enterprise
applications represent leading growth areas.
Strong Multicloud Traffic
Growth Projected
Driven by surging cloud applications, data center
traffic is growing fast. The study forecasts global cloud data
center traffic to reach 19.5 zettabytes (ZB) per year by 2021, up
from 6.0 ZB per year in 2016 (3.3-fold growth or a 27 percent
compound annual growth rate [CAGR] from 2016 to 2021). Globally,
cloud data center traffic will represent 95 percent of total data
center traffic by 2021, compared to 88 percent in 2016.
Improved Security and IoT
Fuel Cloud Growth
In the past, security concerns have been a major
barrier to cloud adoption. Improvements in data center governance
and data control have helped to minimize enterprise risk and better
protect consumer information. Security innovations coupled with
tangible cloud computing benefits, including scalability and
economies of scale, play key roles in fueling the cloud growth
projected in the study. Additionally, the growth of Internet of
Things (IoT) applications such as smart cars, smart cities,
connected health and digital utilities requires scalable computing
and storage solutions to accommodate new and expanding data center
demands. By 2021, Cisco expects IoT connections to reach 13.7
billion, up from 5.8 billion in 2016.
Hyperscale Data Centers
Doubling
The increasing need for data center and cloud
resources has led to the development of large-scale public cloud
data centers called hyperscale data centers. In this year's
forecast, it is expected that by 2021 there will be 628 hyperscale
data centers globally, compared to 338 in 2016, 1.9-fold growth or
near doubling over the forecast period. By 2021, hyperscale data
centers will support:
- 53 percent of all data center servers (27 percent
in 2016)
- 69 percent of all data center processing power
(41 percent in 2016)
- 65 percent of all data stored in data centers (51
percent in 2016)
- 55 percent of all data center traffic (39 percent
in 2016)
"Data center application growth is clearly
exploding in this new multicloud world. This projected growth will
require new innovations especially in the areas of public, private
and hybrid clouds," said Kip Compton, Vice President of Cisco's
Cloud Platform and Solutions Group.
Global Cloud Index
Highlights and Key Projections:
1. Data center
virtualization and cloud computing growth
- By 2021, 94 percent of workloads and compute
instances will be processed by cloud data centers; 6 percent will
be processed by traditional data centers.
- Overall data center workloads and compute
instances will more than double (2.3-fold) from 2016 to 2021;
however, cloud workloads and compute instances will nearly triple
(2.7-fold) over the same period.
- The workload and compute instance density for
cloud data centers was 8.8 in 2016 and will grow to 13.2 by 2021.
Comparatively, for traditional data centers, workload and compute
instance density was 2.4 in 2016 and will grow to 3.8 by 2021.
2. Growth in stored
data fueled by big data and IoT
- Globally, the data stored in data centers will
nearly quintuple by 2021 to reach 1.3 ZB by 2021, up 4.6-fold (a
CAGR of 36%) from 286 EB in 2016.
- Big data will reach 403 exabytes (EB) by 2021, up
almost 8-fold from 25 EB in 2016. Big data will represent 30
percent of data stored in data centers by 2021, up from 18 percent
in 2016.
- The amount of data stored on devices will be 4.5
times higher than data stored in data centers, at 5.9 ZB by
2021.
- Driven largely by IoT, the total amount of data
created (and not necessarily stored) by any device will reach 847
ZB per year by 2021, up from 218 ZB per year in 2016. Data created
is two orders of magnitude higher than data stored.
3. Applications
contribute to rise of global data center traffic
- By 2021, big data will account for 20 percent
(2.5 ZB annual, 209 EB monthly) of traffic within data centers,
compared to 12 percent (593 EB annual, 49 EB monthly) in 2016.
- By 2021, video streaming will account for 10
percent of traffic within data centers, compared to 9 percent in
2016.
- By 2021, video will account for 85 percent of
traffic from data centers to end users, compared to 78 percent in
2016.
- By 2021, search will account for 20 percent of
traffic within data centers by 2021, compared to 28 percent in
2016.
- By 2021, social networking will account for 22
percent of traffic within data centers, compared to 20 percent in
2016.
4. SaaS most popular
cloud service model through 2021
- By 2021, 75 percent (402 million) of the total
cloud workloads and compute instances will be SaaS workloads and
compute instances, up from 71 percent (141 million) in 2016. (23%
CAGR from 2016 to 2021).
- By 2021, 16 percent (85 million) of the total
cloud workloads and compute instances will be IaaS workloads and
compute instances, down from 21 percent (42 million) in 2016. (15%
CAGR from 2016 to 2021).
- By 2021, 9 percent (46 million) of the total
cloud workloads and compute instances will be PaaS workloads and
compute instances, up from 8% (16 million) in 2016. (23% CAGR from
2016 to 2021).
For the purposes of the study, cloud computing
includes platforms that enable ubiquitous, on-demand network access
to a shared pool of configurable computing resources (e.g.,
networks, servers, storage, applications, and services) that can be
rapidly provisioned and released with minimal management effort or
service provider interaction. Deployment models include private,
public, and hybrid clouds. Cloud data centers can be operated
by service providers as well as private enterprises.
Index
Overview:
The Cisco® Global Cloud Index (2016-2021) was developed to estimate
global data center and cloud-based traffic growth and trends. The
report serves as a complementary resource to existing Internet
Protocol (IP) network traffic studies such as the Cisco Visual
Networking Index(TM), providing new insights and visibility into
emerging trends affecting data centers and cloud architectures. The
forecast becomes increasingly important as the network and data
center become more intrinsically linked in offering cloud
services.
