By 2018 cloud will account for 76 percent of total data center traffic


According to fourth annual edition of the Cisco Global Cloud Index by 2018 data center traffic will nearly triple and global cloud IP traffic will account for 76 percent of total data center traffic. Cloud workloads and storage cloud will constantly increase, especially in private sphere.

Traffic data center is traffic that flows from the data center to end users, traffic that flows from data center to data center and the traffic that remains within the data center.
Data center IP traffic will grow at a compound annual growth rate (CAGR) of 23 percent from 2013 to 2018 and cloud will represent about 76%.
IP traffic will reach 8.6 zettabytes (715 exabytes [EB] per month) by the end of 2018, up from 3.1 zettabytes (ZB) per year (255 EB per month) in 2013. 8.6 zettabytes correspond to 250.000 times streaming of all the movies (about 500.000) and tv shows (3 millions) product in UHD (ultr-high definition) up to present day.

By 2018 half of the world’s population will have internet at home and 53% of the contents of these users will be supported by private cloud storage.
When people discuss cloud, they often focus on public cloud services or public cloud storage services. However, a very significant majority of today’s cloud workloads are actually processed in private cloud environments. Even with public cloud workloads having significant growth, by 2018, almost 70% of cloud workloads will still be private cloud-related, requiring the ability of workloads to bridge across a hybrid private/public cloud environment,” said Kelly Ahuja, Cisco, Senior Vice President, Service Provider Business, Products, and Solutions.

Even the number of the Countries that are considered cloud ready is growing. In 2013 the Countries able to support cloud services were 79; this year will be 109.
Internet of things is a potential catalyst for cloud. Most of stored data, indeed, are quickly rejected or not utilized, could be exploit them. For example a Boeing 787 collect 40 TB/h, but only 0.5 Tb are sent to datacenter for the analysis.
