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.
Founded in 1997, Mirror Image Internet is a seasoned service provider with a large portfolio of web and hosting services. The company is principally owned by Xcelera Inc., and is headquartered in Massachusetts, US and has an European sales office in London.
The network map of Mirror Image is not made public on their website, and there is no information on the number of points-of-presence (PoPs). Based on performance comparisons, we think Mirror Image uses the Highwinds network, and add their own intelligence. Note that Mirror Image uses the term “Content Access Point (CAP) facilities” to refer to their PoPs.
Mirror Image Internet hold a variety of patents to protect its core technology. These concern Internet communication, web serving and the distributed selection of content servers.
The company offers features for video streaming and video-on-demand (VOD) through their miPUBLISHER platform. Large file download is also supported. Their control panel ClearVue Control Center includes real-time analytics and the necessary tooling to manage the CDN.
