This project is a good example of how advances in Microsoft’s cloud services allows us to deliver a Content Delivery Network that is not only more cost effective but also gives higher performance than a traditional set-up.

"Shadowfax have delivered a high level of service across technical consultancy, planning and on-going support for our network infrastructure."

Vertical: Hi-tech

Zemax are a global optical software company with their UK office in Stansted Mountfitchet. As a global organisation, Zemax were using a traditional Content Delivery Network to accelerate the distribution of software downloads to their clients. There was a desire to upgrade their IT systems to reduce costs while maintaining performance and high availability.


Project: Cloud Services

Zemax engaged Shadowfax to leverage Microsoft Azure to offer a more flexible and cost effective CDN. We used Microsoft Azure's Verizon CDN as a front end to storage on Azure VMs. The VMs were linked to Azure Active Directory Services to simplify authentication for Zemax staff without the need for web servers to be joined to the Zemax domain by a VPN. The end result was a large cost saving over their existing CDN and increased performance of their software downloads site.
