CacheFly is a Chicago-based CDN provider, with over 40 Points of Presence (PoPs) spread over six continents. Next to the usual locations, Cachefly has PoPs in India, Qatar, Egypt and South Africa.
The Cachefly network is optimised for throughput, making it more suitable for the delivery of large files.
Instead of DNS-based global loadbalancing, the company’s CDN infrastructure relies on TCP Anycast routing.
CacheFly offers the usual features in the CDN industry such as instant purge, origin shielding, real-time reporting and sub-accounts. They also offer a 100% availability SLA and 24⁄7 support.

Microsoft’s cloud computing platform Microsoft Azure includes a CDN service in their offering. The platform was released in 2010, initially named Windows Azure and renamed to Microsoft Azure in 2014.
Azure is an Infrastructure-as-a-Service (IaaS) solution, and next to a CDN they offer storage solutions, data management, compute and networking. Their IaaS solution is similar to Amazon Web Services (AWS) and Google Compute Engine (GCE). Just like Google, Azure offers free credit to first-time users of the platform to help them get started.
The Azure CDN service uses the networks of Akamai and Edgecast, though it is fully integrated with the cloud platform and offered under the Azure brand. Because the CDN service is offered as a part of the larger Azure IaaS ecosystem, it is easy-to-use for businesses who already use the platform. Other CDNs can be used in combination with Azure products as well, for example with their storage solution.
