Not to be confused with Amazon Cloudfront, CloudFlare is a San Francisco-based CDN provider founded in 2009.
The company offers a Free plan, which includes a CloudFlare issued SSL certificate. The features included in the Free plan are basic; more become available to Pro, Business and Enterprise customers.
CloudFlare, together with Akamai, Fastly, Highwinds, Level3 and EdgeCast, is part of the Google Cloud Platform CDN Interconnect program. As part of the collaboration, 30 CloudFlare points-of-presence (PoPs) are directly connected to the Google Cloud infrastructure. When a content request comes in from a Google Cloud origin it will route directly through the interconnect between both parties rather than through the public Internet. As a result, latency is reduced for origin requests. Clients using Google Cloud also receive a discount to their egress traffic.
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.
