Cisco Global Cloud Index (2013 – 2018): Data Center and Cloud Traffic for the Next Five Years
What do our GCI Forecast projections mean for you?
Today, Cisco released the fourth annual update of its Global Cloud Index, or GCI (see media release). For most people who follow cloud-computing, it’s no real surprise to learn that global data center traffic will nearly triple over the next five years or that cloud traffic is expected to nearly quadruple. Examining the trends within the top-line forecast projections is where we begin to see what this growth means for service providers, businesses, and consumers (and how data center networking is being transformed).
For Service Providers and Data Center Operations:
GCI Highlight: The workload density (that is, workloads per physical server) for cloud data centers was 5.2 in 2013 and will grow to 7.5 by 2018. Comparatively, for traditional data centers, workload density was 2.2 in 2013 and will grow to 2.5 by 2018.
The Benefit: An important factor in the rapid expansion of cloud computing is increasing data center virtualization, which provides services that are flexible, fast-to-deploy, and efficient. Virtualized data centers require fewer physical servers and offer great scalability than traditional data centers. This can ease capex and opex pressures (allowing for investment in other areas).
For Large Enterprises and Small-to-Medium Business
GCI Highlight: By 2018, 31% of the cloud workloads will be in public cloud data centers, up from 22% in 2013 (33% public cloud workload CAGR from 2013 – 2018). By 2018, 69% of the cloud workloads will be in private cloud data centers, down from 78% in 2013 (21% private workload CAGR from 2013 – 2018).
The Benefit: As business’ sensitivity to costs related to IT resources grows along with a demand for agility, we expect to see a greater adoption of corporate public clouds. The strengthening of public cloud security will play a key role for many companies’ cloud strategies. While some mission-critical workloads may remain in traditional data centers or private cloud, trust in public clouds is gaining momentum. In general, cloud-computing enables businesses of all sizes to share services and data consistently across global workforces.
GCI Highlight: By 2018, 53% of the consumer Internet population (2 billion users) will use personal cloud storage, up from 38% (922 million users) in 2013.
The Benefit: Consumers want and expect to access their applications and content anytime, from anywhere, from a growing variety of devices. Cloud computing makes this desired ubiquity possible like never before. Cloud-based services such as consumer storage enable users to access their videos, music, pictures and other content seamlessly from multiple devices from virtually anywhere that offers a network connection.
