The key to Microsoft SaaS application performance


Internet connectivity is ubiquitous and is the best option for SaaS applications like Microsoft Teams and Office 365, but how can you overcome network contention and unpredictable routing changes and ensure an optimal user experience?

This is where Colt Cloud Prioritisation is a game changer.

Colt Cloud Prioritisation

Colt Cloud Prioritisation combines the benefits of optimised routing and direct peering infrastructure with traffic prioritisation between customer router and provider edge router. Customers can reach Microsoft Teams, Office 365, Azure, Windows Virtual Desktop, or any other Microsoft SaaS application with a consistent and SLA-backed user experience.

It is one of the first services of its kind to launch at scale in Europe and Asia and works best in conjunction with the new Microsoft Azure Peering Service.

How does Colt Cloud Prioritisation work?

Cloud Prioritisation customers can decide how much of their Internet bandwidth is dynamically reserved for Microsoft. This will work for both incoming and outgoing traffic. Colt has a unique direct interconnection infrastructure with Microsoft in 21 locations across Europe and Asia.

This dense network of interconnections will make sure that the traffic gets to its destination quickly and without unnecessary intermediate stations.
