Public Cloud Computing growing almost 50% annually: Cisco

Further establishes the embrace of cloud computing across all industry sectors

According to a recent Forbes article, Cisco’s latest study concludes that within three years, more than four-fifths of all data center traffic, 83 percent, will be based in the cloud. What’s more, most of this action will be going to public cloud services – there will be more workloads (56 percent) in the public cloud than in private clouds (44 percent).

These are some of the many takeaways of Cisco’s survey of data center traffic, which estimates that more than 500 zettabytes (ZBs) of data will be generated by all people, machines, and things by 2019, almost five times the 135 ZBs generated in 2014. Roughly three to four zettabytes of it moves across data networks at this time, a number projected to grow to 10 ZBs within three years.

Currently, about 65 percent of data center traffic is cloud based, a number that is projected to reach 83 percent by 2019. Workloads are following an almost identical trajectory.

Most of the growth is going to public cloud services, the study’s authors observed. While the overall cloud workloads are growing at an annual rate (compounded) of 27 percent from 2014 to 2019, the public cloud workloads are going to grow at 44-percent rate from 2014 to 2019, and private cloud workloads will grow at a slower pace of 16 percent from 2014 to 2019. By 2018, they estimate, 56 percent of workloads will be in the public cloud.

In terms of type of cloud services, a majority will be applications, as the study finds Software as a Service (SaaS) is and will continue to be the dominant mode. Currently, about 45 percent of cloud implementations are SaaS, compared to 42 percent for Infrastructure as a Service (IaaS — processing, storage) and 13 percent Platform as a Service (PaaS — middleware, development environments, databases). In three years, 59 percent of cloud implementations will be SaaS, compared to 28 percent IaaS and 11 percent PaaS. However, it’s also notable that since cloud adoption is expanding at such a torrid pace, all three modes will keep expanding as well.

The Cisco report also puts things in their proper perspective: “spend on public IaaS and PaaS is still small compared with spend on enterprise data center equipment, data center facilities, and associated operating expenses. These cloud services will gain momentum over the forecast period as more competitive offers come to the market and continue to build enterprise trust for outsourcing these more technical and fundamental services.”
