HomeSolutionsCloud connectivity: Solutions overview

Connect to the cloud on your terms.

In today's world, moving to the cloud is more mission-critical than ever. With nearly 30 years' experience, we're investing not just in our network, but into the service and support that goes with it.

Customers can connect to the public Cloud Service Providers (CSP’s) through the Internet or through a dedicated connection. Colt offers a range of cloud connectivity solutions to fit customer requirements.



Colt connects to more data centres in Europe, Asia and the US than any other provider. More CSPs available upon request.

Your connectivity options explained

We offer a wide range of cloud connectivity options, ranging from standardised IP Transit over the public internet through to dedicated fibre services entirely private to your organisation.


Public internet

Customers can connect to their preferred public Cloud Service Provider (CSP), through our Internet service offerings, arrguably the cheapest and easist way to connect to the cloud. It provides a cost-efficient access method where you don't have specific performance needs. On top of this, Colt is able to offer Cloud Prioritisation, which combines the benefits of optimised routing and direct peering infrastructure with traffic prioritisation.

IP Access with Cloud Prioritisation diagram

IP Access with Cloud Prioritisation works well:

For more critical applications but where public internet will suffice

Where cloud connectivity is being used predominantly for Microsoft applications (Teams, Office 365, Azure or Windows Virtual Desktop)

When a consistent, SLA-backed user experience is required

Dedicated connection

For customers who require maximum security, low latency and high capacity to the cloud backed up with a strong SLA, Colt has created the Dedicated Cloud Access (DCA) portfolio, which provides a best-fit solution for a range of use cases requiring direct connectivity to the cloud. Our different offerings are based on Ethernet (L2), Optical (L1), SD-WAN and IP VPN technologies to meet differrent customer requirements. A number of these solutions are available On Demand, enabling secure and highly scalable connections to the cloud, in minutes.


Dedicated access works well:

Where you do not wish for your traffic to traverse the public internet, and a dedicated fibre connection is required

For mission critical applications

Where SLA-backed performance is a must
