Global cloud computing traffic will grow 12-fold from 130 exabytes to reach a total of 1.6 zettabytes annually by 2015, which means a 66% compound annual growth rate, according to Cisco’s Global Cloud Index (2010 – 2015) report.
In conjunction with the report, Cisco also unveiled its CloudVerse offering, which is a framework that combines the elements needed to enable organizations to build, manage and connect public, private and hybrid clouds.

The news indicates that Cisco is increasing its efforts toward cloud computing, which is becoming a critical element for the future of information technology and delivery of video and content. In announcing its its CloudVerse service, Cisco said that today most cloud technologies exist in silos, preventing an efficient, integrated management approach.
Cisco said it is aiming to deliver a cloud experience within the cloud, between clouds, and beyond the cloud to the end user.
According to its index, Cisco claims that by 2015, 76% of data center traffic will remain within the data center itself as workloads migrate between various virtual machines and background tasks take place; 17% of the total traffic will leave the data center to be delivered to the end user; while 7% of total traffic will be generated between data centers through activities such as cloud-bursting, data replication and updates.
The index also notes that the cloud will account for one-third of total data center traffic. To address that need the company claims that greater virtualization and improved economies of scale will be a key driver of the cloud transition.
Global cloud traffic is forecast to grow twice as fast as global data center traffic, with global data center traffic expected to more than quadruple from 1.1 zettabytes in 2010 to 4.8 zettabytes annually in 2015, representing a 33% CAGR.
The study also notes that due predominately to the rise in video-based consumer services, data-center-to-user traffic will have significant peaks in activity. Much like “prime time” television viewing, the average amount of data center traffic per hour during peak periods is expected to increase up to 2.5 times, requiring the need to plan for additional capacity from data centers and the cloud as well as from the network.
