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).

MegaTrends: The Need for Securing Data Center Traffic

Data Centres are evolving rapidly, in response to the many industry IT Megatrends we have previously discussed. Services and applications are increasingly being delivered from very large data centres and, increasingly, from hybrid and public clouds too.

Specifically, a good example of services being delivered from data centres is Hosted Desktops. I discussed in my last post how technologies such as TrustSec can help secure VXI/VDI deployments. VXI is a good example of a service originally delivered only from private data centres, now being delivered As A Service as well.

Video is (and will be) increasingly delivered from data centers as a service. Infrastructure services (servers/VM, storage…) are also delivered internally more and more through Private Clouds.

Consequently, securing those environments is now perceived by our customers CTOs and architects, as the biggest barrier to adopting clouds on a much larger scale.

We will therefore look at how TrustSec can pervasively help secure all data centre traffic. Read More »
