CDNsun was started in 2012 in Prague, Czech Republic as a low cost content delivery network. The network is powered by the OnApp federated CDN platform. OnApp is a wholesale content delivery network that gives service providers access to up to 170 points of presence around the world via the OnApp Federation (essentially selling unused capacity on other providers’ networks). Today, CDNsun has over 70 POPs worldwide and even supports HTTP/2.
The primary selling point of CDNsun is low pricing with no commitment and a free trial period that makes it easy for small companies to get started. They do offer basic features like SSL, storage, token authentication, and live streaming.
The CDNsun network consists of roughly 70 points of presence globally across N America, Europe, and Asia Pacific. They also have one POP in Brazil and several in India. All servers are solid-state drives and are connected to the largest Tier 1 networks. CDNsun utilizes the OnApp federation, which is a global network of wholesale clouds that can be used to scale up to 170 locations on demand.
CDNsun pricing is completely transparent and shared on their website. You pay for how much data transfer you need per month with no hidden fees and no long term commitments. Rates start around $.045/GB for global delivery and go down with volume. They charge one rate for delivery anywhere in the world. All plans contain the same feature set.
CDNsun is fairly limited in features but offers all the basics to cover video delivery, software downloads, and basic caching. They do offer transcoding for video delivery and even support HTTP/2, which is something only a handful of CDNs have adopted. The biggest advantage of CDNsun is affordable pay as you go pricing with no commitment while still getting access to a large global network footprint.
Why Choose CDNsun?
CDNsun doesn’t actually own or operate any of their own datacenters, but rather they resell CDN from the OnApp Federation. While this may not make them a great choice for everyone (some may be concerned with lack of support or features), they do offer a very cost effective service with a large network footprint. For companies less concerned with all the bells and whistles and who just want to get their site served globally at a low cost, CDNsun is your vendor.
