Cloud Seen Driving Data Center Traffic; to Surge by 2015
Cloud is in. The cloud, a significant component that would rewrite the future of information technology and video/content delivery, is being seen by conglomerates as an important arena to log on to. With more companies getting on to this new computing services terrain, the cloud is turning out to be the fastest growing component of data center traffic.
Estimates are that the cloud will grow four-fold at 33 percent compound annual growth rate (CAGR) to touch the 4.8 zettabytes mark annually, by 2015. It has been pointed out that cloud comprises 11 percent of data center traffic, and would be up by 33 percent of the total by 2015.
The estimates, revealed in the inaugural Cisco Global Cloud Index (2010 – 2015), also forecast global cloud computing traffic to grow 12-fold from 130 exabytes to reach a total of 1.6 zettabytes annually by 2015. That would be a 66 percent CAGR.
In case you aren’t aware, 1.6 zettabytes is almost equivalent to 1.6 trillion hours of online high-definition (HD) video streaming. It may be seen as the transition to cloud services is driving global cloud traffic at a growth rate that is twice as great as global data center traffic is now.
The Cisco index also points out that it is not the end users, but large data centers and clouds who undertake activities most often transparent to end users, like backup and replication, who are responsible to the burgeoning traffic.
The data centers would be seen as responsible for around 76 percent of the traffic by 2015, thanks to the migration of workload between virtual machines and background tasks.
As per the index, data centers would see 17 percent of the total traffic taken off from themselves so as to be delivered to the end user. Meanwhile, another 7 percent of traffic would be generated between data centers via cloud-bursting, data replication, updates and other operations.
