Gear Up for a Cloud Boom
Key drivers of the transition to cloud services include personal cloud demands, public cloud services, virtualization in private clouds and more.
Cloud Traffic Accelerates
Global cloud traffic will grow from 2.1 zettabytes (ZB) in 2014 to 8.6ZB in 2019, outpacing the growth of global data center traffic, which should increase from 3.4 to 10.4ZB over the same period.
A Bigger Piece of the Data Center Pie
83% of global data center traffic will come from cloud services and applications.
North America Rules Data
North America is forecast to have the highest cloud traffic volume (3.6ZB) by 2019, followed by the Asia-Pacific region (2.3ZB) and Western Europe (1.5ZB). North America will also have the highest data center traffic volume (4.5ZB) by 2019, followed by the Asia-Pacific (2.7ZB) and Western Europe (1.8ZB).
Big Growth Potential
Global IoT connections are predicted to reach 507.5ZB of data annually by 2019. This is up from 134.5ZB in 2014.
Mobile Devices Gobble Up Data
Today, 73% of data stored on client devices resides on PCs. By 2019, 51% of stored data will move to non-PC devices, such as smartphones, tablets and M2M modules.
Personal Clouds
By 2019, 55% of global consumer Internet users will use personal cloud storage, up from 42% in 2014.
Data Center Virtualization
Workloads per physical server for cloud data centers is expected to reach 8.4 by 2019, up from 5.1 in 2014. In comparison, workload density for traditional data centers will grow to 3.2 by 2019, up from 2.0 in 2014.
Private vs. Public Cloud
Public cloud workloads are forecast to grow at a 44% compound annual growth rate (CAGR) from 2014 to 2019, while private cloud workloads will grow at a 16% CAGR over the same period.
Workloads in the Cloud
By 2019, 56% of the cloud workloads will be in public cloud data centers, up from 30% in 2014. In comparison, 44% of the cloud workloads will be in private cloud data centers by 2019, down from 70% in 2014.
SaaS Adoption
By 2019, 59% of the total cloud workloads will be SaaS, followed by IaaS (28%), and PaaS (11%).
