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.
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.
