We make it easy to establish a dedicated network connection from your premises to your Microsoft Azure cloud through Azure ExpressRoute.

Secure and reliable connectivity to the Microsoft Azure Cloud

Establish private connectivity from your data centre, office or co-location environment to reduce your network costs, increase bandwidth throughput and provide a more consistent network experience than Internet-based connections. Under our Cloud Connect service, we can provide secure and reliable network connectivity between enterprise data centres or office locations and the Azure or Office 365 clouds through Microsoft's ExpressRoute service.

Colt is an Microsoft ExpressRoute Technology Partner, and we provide Ethernet connectivity services (with an option managed router add-on) and IP VPN access to the Direct Connect private network access points. Colt is also able to provide a seamless integration of Microsoft Azure into our SD WAN and IP VPN network solutions.

With our cloud connectivity solutions, customers can choose to connect to a single cloud provider (point-to-cloud), or to multiple cloud providers (point-to-multi-cloud). Our solutions also support cloud-to-cloud connectivity options.

Your benefits at a glance:

Enhanced Security

The traffic between any enterprise site and ExpressRoute access Point of Presence is routed entirely across the Colt network, so that customers can be assured that their mission critical traffic is safe in our hands.

Better Resilience

Colt's award-winning network services are provided with a high degree of resilience. Moreover, customers have a number of enhanced configuration options for Disaster Recovery and High Availability purposes.

Faster Performance

Colt operates one of the lowest latency networks in Europe and Asia, so data is routed over the lowest-latency paths to the Microsoft cloud, to create the most seamless performance possible.

Predictable Experience

Making your traffic independent of the internet means that your customers and your business users can enjoy consistent performance from your apps, without drops in performance that are out of your control.

Get advice and help setting up the best, and most efficient, cloud network for your business with our dedicated, knowledgeable customer support team, with our 24/7 multilingual support facility which supports our service SLA. Our proposition is recognised every year by the Metro Ethernet Forum (MEF) as industry-leading.


On Demand Capability

Colt Dedicated Cloud Access service is also available On Demand to disrupt and transform the users experience. Thanks to SDN technology, our customers benefit from real-time ordering, provisioning and service flexing through a self-serving portal.

This includes a range of connectivity options that have been customised for better integration into the ExpressRoute, such as Point-to-Point Ethernet for customers who need to connect a single site, and IP-VPN for customers who want to share Azure access access across multiple sites.

Once you have put in place an ExpressRoute connection, you will be able to consume Azure cloud services and Office 365 across secure and reliable network connections.

Accessing the Microsoft Azure Cloud

Azure separates access points (“PoP”) from the Data Centres (“regions”) in which the services are housed.

Colt can provide direct fibre based connectivity into the majority of Azure PoPs in Europe, Asia Pacific and North America, which simplifies speeds provisioning, and provides optimum traffic routes for customers.

Moreover, Colt addresses your business locations with connections into 212 cities globally. More than 29,000 direct fibre connected buildings and 900+ third party data centres. With Colt’s worldwide connectivity network, we ease the way to connect your network into the cloud.

Service Features

Colt cloud connectivity services include point-to-cloud and point-to-multi-cloud Ethernet cloud connectivity for customers who want to connect to a single customer site. Customers can also choose an optional ‘managed router’ add-on.

For multi-site solutions, Colt SD WAN Multi-Cloud and Colt IP VPN enable direct, reliable and secure connectivity from branch sites towards cloud service providers. These solutions also support cloud-to-cloud connectivity.

Azure ExpressRoute services are always made up of two parallel circuit paths. Once you have put in place an ExpressRoute connection, you will be able to consume Azure cloud services and Office 365 applications across secure and reliable network connections.

Colt supports both Microsoft ExpressRoute and Microsoft ExpressRoute Direct.
