Cisco predicts 12-fold growth for cloud computing traffic by 2015

LEADING technology solution company, Cisco has predicted that cloud computing traffic would have grown 12 times more by 2015.Cisco, in its inaugural Cisco Global Cloud Index (2010 ' 2015) study reveals the dramatic changes clouds services are bringing to business and transforming Information Technology and consumer services, forecasting that over 50 per cent of computing workloads in data centres would be cloud-based by 2014.Besides, the study also revealed that the global cloud traffic would grow over 12 times by 2015, to 1.6 Zettabytes/year.This, according to the study, is the equivalent of over four days of business class video for every person on earth to 22 trillion hours of streaming music.It explained that cloud is the fastest growing component of data centre traffic, which itself will grow fourfold at a 33 per cent CAGR to reach 4.8 zettabytes yearly by 2015. Cloud is also estimated today to be 11 per cent of data centre traffic, growing to more than 33 per cent of the total by 2015.According to Cisco, cloud is becoming a critical element for the future of IT and delivery of video and content. The vast majority of the data centre traffic is not caused by end- users but by the data centres and clouds themselves undertaking activities that are largely transparent to end- users ' like backup and replication.By 2015, according to the study, 76 per cent of data centre traffic will remain within the data centre itself as workloads migrate between various virtual machines and background tasks take place.The study added that 17 per cent of the total traffic leaves the data centre to be delivered to the end- users, while an additional seven per cent of total traffic is generated between data centres through activities such as cloud-bursting, data replication and updates.The study suggested that the predicted explosive growth in cloud and data centre traffic would create the need for advanced capabilities that allowed the data centre and network to work together to support end-to-end cloud application and service delivery.The acting General Manager, Cisco Nigeria, Mr. Said Rechchad, disclosed the availability of the Cisco CloudVerse, a technology solution that enhances the building, management and connection of clouds.
