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.
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.
