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.
Founded in 2011, Fastly is a relatively new player in the CDN market. As of 2015, the company has raised $130 million from investors Battery Ventures, IDG Ventures, August Capital, O’Reilly AlphaTech Ventures, Amplify Partners and ICONIQ Capital.
Self-proclaimed ‘new generation CDN service’, Fastly offers a full-SSD network and PoPs in North America, Brazil, Europe, APAC and Australia & New Zealand. Their Fastly Cloud Accelerator partnership with Google allows Fastly clients to connect directly to the Google Cloud backbone, and configure a Fastly origin shield in front of their GCE storage bucket. The partnership might be considered a way for both parties to compete with Amazon Web Services (AWS), and their S3 storage solution and Cloudfront CDN service. Other CDN providers participating in the Google Cloud Platform CDN Interconnect program are EdgeCast, Highwinds, Level3, Akamai and CloudFlare.
Fastly uses web application accelerator Varnish, and allows clients to upload their custom VCL (Varnish Configuration Language) to the Fastly platform. Currently, there is one alternative to Fastly when it comes to uploading custom VCLs, and that is ‘developer CDN’ section.io.
On-boarding with Fastly is quick & easy and can be done without intervention a sales representative. Their extensive API-tools include purging, stats and config management. For an overview of Fastly’s features, check out the table below or make comparisons with other CDN providers.
