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.
Level3 Communications is an Internet Service Provider (ISP) and a provider of telecommunication services. The company was founded in 1885 and is currently headquartered in Colorado, in the United States. The Level3 brand is well-known; the company operates a large, physical network of the Internet and offers a wide range of networking services. Level3 is the network, and it owns a Tier 1 backbone and operates its own points-of-presence (PoPs). One notable customer of Level3 is Netflix.
Level3 has made some notable acquisitions, including companies such as Black Lotus (DDoS protection), TW Telecom (business Internet solutions), Genuity (AS1) and the CDN services business of Savvis - a subsidiary of CenturyLink that provides hosting and colocation services. The CDN was acquired in 2006 and is run by Level3 to this day. In 2016 Level3 has been acquired by CenturyLink.
Additional CDN-related services by Level3 include DDoS protection, SSL, Encryption, Geo Blocking, (live) video streaming and website acceleration.
Together with Fastly, CloudFlare, Highwinds, Akamai and EdgeCast, Level3 is part of the Google Cloud Platform CDN Interconnect program. The interconnection agreement between the backbones of both parties will benefit customers on both sides; traffic over these interconnects enjoys reduced latency and increased reliability compared to the public Internet. Clients using a Google Cloud origin receive a discount to their egress traffic when peering with Level3 or any other CDN that is part of the collaboration.
Level3 does not publish customer information. CDN overview has located some of customers of the CDN service, such as CloudVPS. We’ll keep the list updated.
