Size isn’t everything – it’s reach that counts. How CDNsun built a unique content delivery service.

CDNsun - web acceleration, software delivery, RTMP, live streaming powered by OnApp

CDN is one of the fastest-growing segments in the service provider market – and you don’t have to be big to build a successful CDN business.

Success comes from finding and owning a unique place in the market, and that’s exactly what CDNsun has achieved.

We caught up with David Pospisil, CEO of CDNsun, to discuss changes in the CDN market, and how the CDNsun team has been able to build a unique and successful service, with the help of their OnApp CDN platform.

“We’re a boutique CDN provider by design,” he says. “We’re one of the smallest CDN providers on the market, in terms of monthly traffic, but one of the biggest in terms of reach. We made a conscious decision to focus on companies who have relatively modest CDN traffic requirements but who need flexible global coverage – because that’s where we can offer better features, better support, more CDN locations and lower prices than anyone else on the market.”

From software delivery to online gaming

CDNsun customers range from organizations like the Blender Institute – a name that’ll be instantly recognizable to anyone familiar with 3-D modelling, animation and video – to online gaming companies, audio streaming companies and a wide range of website owners.

“We’re B2B-oriented and technical specialists. We prefer to deliver the features our customers need, rather than oversimplify – and our team works with corporate IT people who need that level of understanding,” says David. “We are totally focused on reliability and performance, too: CDN is essential to our customers’ business models, so we provide all-SSD infrastructure, the highest quality PoPs, and proactive support across the board – all without breaking the bank.”

Size isn’t everything – it’s reach that counts

While CDNsun focuses on customers with relatively low traffic volumes, its global reach is huge – and that’s essential to being able to provide low latency content delivery for clients with customers across the world. CDNsun can offer 170 points of presence in 93 countries, and the federated nature of OnApp’s CDN platform plays an important role in this.

Using OnApp means CDNsun has access to a global network of CDN infrastructure – the OnApp Federation – and can easily add locations to its own, in order to provide fast local delivery for its customers’ content, anywhere in the world. The OnApp Federation is a marketplace for service providers, where they can buy compute and CDN capacity on demand and use it as part of their own services.

Low latency streaming

CDNsun uses OnApp to provide a full range of content delivery services, from web acceleration to live streaming, video on demand, software and game delivery, and extremely low latency RTMP streaming.

“OnApp CDN supports RTMP, and that has been very good for business – even though RTMP is a protocol the industry has largely moved away from, preferring to focus on HTTP streaming instead,” David says. “RTMP is still the performance king when you absolutely need low latency. Live auctions and sports betting are two prime use cases: RTMP is faster, and while browsers like Chrome don’t support it, that isn’t a problem because these types of company use their own client applications for their service.”

From web acceleration to 5G and edge

What changes has CDNsun seen in the market since 2012? There is continuing demand from companies in the US and Europe, and Taiwan, Singapore and Hong Kong are all CDN-hungry countries in Asia, says David.

“In terms of customers, demand for CDN really comes from three main groups: website owners, whether they’re running e-commerce sites or just looking to maximize performance for their corporate site; companies using CDN to deliver assets they create, especially software packages; and companies doing live streaming, especially multi-bitrate streaming.”

“Companies are more and more interested in securing their CDN with SSL – in other words, using https instead of http. This trend is being accelerated by Chrome, which basically doesn’t support http any more.”

“As for the future, I think we’re going to see a lot more focus on edge computing when 5G networks become commonplace. When you have fast local Internet access, it doesn’t make sense to process data at a central datacenter, then send it back to end users. Local content caching will co-exist with local compute to maximize speed.”
