In the recent reports CISCO has come up with staggering figures, indicating cloud traffic will grow tremendously as the demand increases.Showing concerns and suggesting data center have to be equipped with an aggressive tool and architecture to support the eco system called cloud. Traffic which is at 11 percent in 2010 is expected to blossom to 34 percent by2015, from 11 Exabyte’s of data per month to 137 exabytes of data per month, making it annually 1.6 zettabytes by 2015.

 

 

Cisco describes this growth as approximately equivalent to:

–           22 trillion hours of streaming music;

–           5 trillion hours of business Web conferencing with a webcam; or,

–           1.6 trillion hours of online HD video streaming.

Now traffic is not generated through the end user, but mostly due to non transparent activities happening at the background between the cloud infrastructures.  This includes line backup and replication of data, workload bouncing between various virtual machines as the backend task remain scheduled and auto running.

As per Cisco reported article  “By 2015, 76 percent of data center traffic will remain within the data center itself as workloads migrate between various virtual machines and background tasks take place, 17 percent of the total traffic leaves the data center to be delivered to the end user, while an additional 7 percent of total traffic is generated between data centers through activities such as cloud-bursting, data replication and updates.”
