Cisco Predicts 94% of Workloads Will Be Cloud Based By 2021

The seventh annual Cisco Global Cloud Index has highlighted how the demand for cloud could see workloads being processed by cloud datacentres increase to 94% by 2021, compared to 88% recorded in 2016.

The huge growth we are expected to see in cloud-based data is mainly down to the growth of Internet of Things (IoT) applications and the overall improvements seen in data centre governance and data control that have reduced security issues. With the number of IoT connections on earth expected to reach 13.7 billion by 2021, up from 5.8 billion in 2015, they will require cloud datacentres in order to facilitate the demands.

The growing demand for cloud-based services is coming from both businesses and customers. Consumers are using social networking sites, video streaming and other internet services more than ever before and this is only going to grow rapidly in the future as technology advances. When it comes to businesses, it seems the demand is a result of increasing use of cloud-based enterprise resource planning (ERP) tools, collaboration platforms and analytics services.

The density of workloads in cloud datacentres is also expected to increase from now to 2021 from 8.8 to 13.2. This is over triple the density of workloads forecasted for traditional datacentres, which are expected to rise to just a mere 3,8 from 2.4 in 2021.

Cisco also predicted in the Global Cloud Index that the increasing need for datacentre and cloud resources will in-turn lead to the number of hyperscale datacentres to double by 2021 to 628. Hyperscale facilities will house 55% of all datacentre traffic by 2021 and will support 53% of all datacentre servers.

Software-as-a-service (SaaS) will continue to dominate cloud service models with SaaS predicted to be accountable for 75% of the cloud workloads. Infrastructure-as-a-service (IaaS) will account for 16% and platform-as-a-service (PaaS) will account for 9%.

Vice President of Cisco's cloud platform and solutions group spoke in the press release saying "Data Centre application growth is clearly exploding in this new multi-cloud world. This projected growth will require new innovations especially in the areas of public, private and hybrid clouds."
