The inaugural Cisco Global Cloud Index (20102015) has predicted that cloud computing traffic would have grown 12 times by 2015.The study, which forecasts how dramatically clouds are changing business Information Technology and consumer services, predicted that over 50 per cent of computing workloads in data centres would be cloud-based by 2014.It also predicted 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.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 annually 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- userslike 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 which enhances the building, management and connection of clouds.Rechchad described it as a framework that combined the foundational elements Unified Data Centre, Cloud Intelligent Network, and Cloud Applicationsneeded to enable organisations to build, manage and connect public, private and hybrid clouds. He said the technology allowed businesses to realise all of the benefits of clouds such as improved agility, better economics, enhanced security and a dynamic, assured experience.He said, Today, most cloud technologies exist in silos, preventing an efficient, integrated management approach. By integrating the three foundational cloud elementsthe Cisco Unified Data Centre with the Cisco Intelligent Network to enable Cloud ApplicationsCloudVerse delivers a business-class cloud experience: within the cloud; between clouds; and beyond the cloud to the end- user.He said, Cisco uniquely enables the world of many cloudsconnecting people, communities and organisations with an assured cloud user experience for the next-generation Internet.'We are very pleased that many of the worlds leading businesses and service providers are adopting Cisco CloudVerse as the foundation of their cloud strategies, and we look forward to partnering closely with each of them on their journey to a world of many clouds.
