Cloud computing has become a staple option for many businesses and individuals over the last few years and is now expected to grow rapidly, reports Tech.Co. Recent predictions from Cisco estimate that cloud computing will soon quadruple on current figures, meaning that just eight per cent of workloads will be processed by traditional data centres.

By 2020, Cisco predicts that 92 per cent of workloads will go through cloud data centres, highlighting the need for businesses to have cloud systems in place now. This will also lead to a number of challenges for those using the cloud, including 14.1 zettabytes (ZB) of traffic.

This growth is not just due to increased cloud workloads, but also increases in big data and the Internet of Things (IoT). In fact, data produced by the IoT is expected to reach around 600 ZB per year, which is more than both traffic from data centres to users (2.2 ZB) or data centre traffic in general (15.3 ZB). 

A decrease in private data centre workloads is also expected in 2020 compared to 2015 figures. It is predicted that these will fall by 19 per cent, with this data going through public cloud centres instead. Cisco suggests that this will be due to a rise in hybrid cloud strategies, including things like like cloud bursting, which allows public cloud centres to accommodate spikes in traffic. 

One thing that is expected to remain much the same is Platform as a Service (PaaS), with just a one percentage point change being predicted. However, Software as a Service (SaaS) will see a small increase of nine per cent from 65 per cent to 74 per cent in terms of total cloud workloads.

With companies working to improve their own internet infrastructures, Cisco is expecting Infrastructure as a Service (IaaS) to see a nine per cent decline. This is due to the need for increased storage capacity and high speed connections as more businesses make use of cloud computing.
