HomeWhy Colt?Our PartnersColt cloud connectivity options for Microsoft Azure

Transforming enterprise together

Leveraging our Gold partnership with Microsoft, we've developed a comprehensive set of cloud connectivity and voice services for organisations that want to adopt cloud services in their digital transformation journey.

Enterprises who prefer a dedicated layer 2 connectivity can connect via Microsoft’s Azure Express Route thanks to Colt Dedicated Cloud Access proposition.

As an alternative, enterprises can also connect Colt’s IP Access to the public Microsoft Azure domain, avoiding all the typical challenges experienced by connecting to the cloud over public internet – unpredictable performance, availability and latency – thanks to Colt being a partner for Microsoft’s Azure Peering Services.

To further strengthen Colt’s positioning in the Microsoft Azure ecosystem, Colt is also joining Azure’s Networking MSP Partners Programme. This gives Azure enterprise customers access to an industry-leading networking experience which helps them to connect, operationalise, and scale the adoption of their cloud services on Azure.

Furthermore, Colt can offer a unique one-stop IT capability by integrating the power of Microsoft’s Office 365 and Teams with Colt’s voice and data networks, with its Intelligent Communications solution.
