G-Core, or G-Core Labs S.A. is an IT solutions provider based in Luxembourg, with offices in Moscow, Minsk and Perm. In 2017 G-Core Labs acquired SkyparkCDN. The company offers a variety of services such as peering network, hosting and CDN services. G-Core was founded in 2014 by the team behind Wargaming Interactive, the Russian game development studio of World of Tanks and World of Warships.
Developed to support online gaming, G-Core’s core KPIs are low latency, high availability and cost optimisation. From their experience with the Wargaming user base, a gaming-tailored CDN and IT infrastructure emerged that is both suitable for gaming parties, as well as clients in any other web content industry. G-core’s infrastructure was the backbone for the world record of (‘Most Players Online Simultaneously on one MOG Server’), officially awarded to Wargaming, for serving 1.114.000 gamers simultaneously.
G-Core is what we consider a local or regional CDN provider and focuses on the Russia and CIS region. With 15 PoPs spread across all regions in Russia and CIS, the company aims to provide the most optimal content delivery to gamers and web users in the area. However, they have also expanded outside of Russia and the CIS region with PoPs in Europe, North-America, and Asia for a total of 36 PoPs.
Next to their CDN services, G-Core provides cloud hosting, co-location, DDoS protection, private information policy assistance and a wide range of support services to their clients. G-Core uses OpenStack to manage their networking, compute and storage resources.
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.
