Limelight Networks is an Arizona-based CDN provider that owns and operates its own content delivery network. The company was founded in 2001 and has offices in the US, Europe and Asia.
Limelight offers regular CDN services for static content, website acceleration, video streaming (Limelight Orchestrate) and cloud storage. Some of the services in the Limelight portfolio came to be from a variety of acquisitions done by the company in the past. Acquired companies include AcceloWeb (website acceleration), Kiptronic (video) and Delve Networks (video).
In 2006, the CDN provider was sued by Akamai Technologies, Massachusetts Institute of Technology (MIT) and later by Level3 over alleged patent infringements. In 2015, after a long string of decisions, came an end to the back-and-forth between Akamai and Limelight: Limelight was held liable for direct infringement of an Akamai-held patent by the US Court of Appeals for the Federal Circuit. In response to the ruling, Limelight Networks (NASDAQ:LLNW) fell greatly.
As of today, Limelight is still fighting a portion of the August 2015 decision, prolonging an already long-standing dispute against Akamai.
Limelight serves, or has served notable customers such as Disney, EA Sports, MySpace, Harpo Productions, MTV, Nintendo, Heineken and Carrefour. With the exception of the latter two, these customers are seemingly no longer with Limelight.
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.
