Data Centre connectivity: Managing the Cloud


The fifth annual Cisco Global Cloud Index in October 2015 forecast that global cloud traffic would more than quadruple by the end of 2019, from 2.1 to 8.6 zettabytes (ZB), outpacing the growth of total global data centre traffic, which is still forecast to triple during the same time frame (from 3.4 to 10.4 ZB). This has major implications for data centre connectivity.

It is now widely accepted that cloud is moving well beyond a regional trend to becoming a mainstream solution globally, with cloud traffic expected to grow more than 30% in every worldwide region over the next five years. Businesses are moving from testing cloud to trusting it. At the same time, consumers continue to expect on-demand, anytime access to their content and services nearly everywhere.

To help take all of this in, we have produced a more easy-to- digest infographic to outline these trends – and also demonstrate what it really means to businesses.

Cloud applications drive unpredictable traffic. From an individual customer point of view, specific traffic trends on cloud-based networks are difficult to predict, given the spontaneous access to cloud-based resource pools by a wide variety of users and applications.

What is needed to really make your cloud enterprise-class is a network that can react to change — such as one that can cope with multiple simultaneous failures; a change in network topology; or an increase in latency in some of the network’s critical spans. You also need a network that handles and executes daily operations — such as bandwidth increase requests, setting up a new connection between two end-points, or modifying an existing connection — in real time, without requiring any human intervention.

DCNet on Demand offers low latency with Guaranteed Bandwidth with each connection. Customers can add new sites and create connections in near real time and then modify their bandwidth  instantly, as many times as they need. You can select scalable bandwidth from 10Mbps to 10Gbps and benefit from a Pay-as- you-go billing model with a flexible rolling monthly contract.

With Colt’s DCNet On Demand data centre inter-connectivity service, we offer award winning Ethernet services between key cloud and other data centres across Europe. Our self-service portal allows you to provision connections instantly, expand into new data centre locations across Europe and Asia, and scale your bandwidth in real time.
