Cisco number crunchers think that growing demand for cloud and online services means 92 percent of applications and workloads will run in large-scale, cloud data centers by 2020.
The networking giant’s sixth annual Global Cloud Index report contains a series of divinations and oracles charting how enterprise and consumer use of off-premise services is set to change between now and 2020.
According to the entrails of a rather healthy ram, the amount of cloud-based IP traffic will rise from 3.9 zettabytes to 14.1 zettabytes by 2020, as enterprises and consumers ramp up their use of off-premise apps and services in the years to come.
Meanwhile, according to the way that the chickens are fed, the amount of traffic passing through traditional, enterprise data centers will hit 1.3 zettabytes by 2020, up from 827 exabytes per year in 2015.
The Cisco Sybil, who after chewing laurel leaves and breathing in toxic fumes, said that by 2020, this means just eight per cent of workloads are likely to run in private datacentres, while remaining ones will be hosted in hyperscale, cloud datacentres.
After the priests of Apollo analysed the sooths, Cisco said it expects around 68 per cent of workloads to run in public cloud datacentres by 2020, up from 49 per cent in 2015. Meanwhile, 32 per cent will be hosted in private cloud facilities, which represents a marked drop from 51 per cent last year.
For the first time, Cisco’s oracles have provided a breakdown of how the rise of hyperscale datacentres which are the sorts of things that Facebook, Amazon and Google are running.
Between 2015 and 2020, Cisco believes the number of hyperscale datacentres in the world will increase from 259 to 485, coinciding with a quintuple rise in the amount of network traffic being routed to them.
Hyperscale facilities will house around 47 per cent of the world’s total installed datacentre servers, and support 53% of all datacentre traffic by 2020.
While Cisco acknowledges that IoT will be the source of massive amounts of data as more devices come online, at this stage it is unclear how much of that information will need to be stored in datacentres and how much will be processed locally on devices.
“Globally, data generated (but not necessarily stored) by IoT will reach 600 ZB per year by 2020, 275 times higher than projected traffic going from datacentres to users/devices,” the report said.
