Joe McKendrick – an individual contributor for the Tech Blog of Forbes magazine writing in his latest blog quotes Cisco estimates to tell how cloud computing is becoming all pervasive technology in the coming years. He deploys significant figures from the Cisco estimates estimate to establish this, like with cloud traffic increasing 3.9 zettabytes ( ZT) in 2015 expected to reach 14.1 zettabytes by 2020 and also the likelihood of 92% of the workloads processed by cloud datacenters with only 8% of the remaining being processed by the traditional data centers in the coming few years.
According to this estimate, Big Data and the associated Internet of Things (IoT) will be the prime drivers for the growth of cloud computing. By 2020, database, analytics and IOT will amount to 22% of the workload against 20% in 2015. The estimated volume of data generated by IoT will be around 600ZT by 2020, which is expected to be 39 times the total projected data center traffic at 15.3 ZT in 2015.
Talking about the composition of the cloud, Cisco estimates by 2020, 68% of cloud workloads will be in public cloud up from 49% in 2015; this against 32% of cloud workloads in private cloud down from 59% in 2015. And as Cisco team explains, this shift from private to public cloud will be because of the organization’s deployment of hybrid cloud strategy. According to which private cloud will address the daily computing needs and public will be deployed to address the sudden spurts in demand in traffic.
While Cisco estimates that Software as a Service (SaaS) for online applications and platform as a Service (PaaS) for development tools, databases and middleware is projected to grow, Infrastructure as a Service (IaaS) for online servers, storage is expected to see a drop in demand, and this too according to Cisco analysts will be attributable to the organization’s growing desire to deploy hybrid cloud strategy.
And coming to the consumer usage of cloud, by 2020, cloud storage traffic per user will be 1.7GB/month compared to 513MB/month in 2015, and this will be mainly driven by video and social networking workloads.
