Cisco forecast that nearly all workloads will be in the cloud by 2020Cisco revealed in its Global Cloud Index that 92% of all workloads will be in the cloud by 2020 and the rest will be processed in traditional data centres. This means that the workload density in the cloud will more than triple from 7.3 in 2015 to 11.9 in 2020. Within the enterprise segment compute and collaboration are the top contributor to workload totals while more predictably for consumers, video streaming and social networking are the two main contributors. By 2020, the global cloud traffic will peak at an impressive 14.1 zettabytes per year, from a meagre 3.9 in 2015. This is due to a greater degree in data centre virtualisation that gives impetus to the growth of cloud migration. One important feature in this migration is the the increasing popularity of public over private cloud. Cost effectiveness and the improvement of public cloud security are some of the reasons why enterprises are predicted to adopt the public cloud: “As the business sensitivity to costs associated with dedicated IT resources grows along with demand for agility, we can see a greater adoption of public cloud by businesses, especially with strengthening of public cloud security” To read more about the Global Cloud Index, see the complete Cisco report here.
