Vietnam is one of the fastest growing economies in Southeast Asia, but like many emerging economies – India, China and Brazil for example – Vietnam is still playing catch-up when it comes to network connectivity.
The bandwidth available in connections to the outside world is very limited; even when comes to local telcos, their peering arrangements are not as mature as you might see in Europe, for example.
So, how can a country like Vietnam overcome these issues, and help to drive even faster growth? This is where “Local CDN” is an awesome use case.
How VietnamCDN ensures performance
We worked with Vinacis, a leading Vietnamese cloud provider, to create a unique setup for their new CDN brand, VietnamCDN. We helped them to overcome peering limitations by using OnApp CDN to redirect visitor content requests to caching servers which run on the “right” telco’s network, even if there are multiple caching servers in the same region.
This is a very different CDN redirection methodology compared to most CDN providers out there, which use geographical location as the main metric to decide on traffic redirection.
To show you an example of what I mean, here’s a screenshot from one of the CDN analysis tools we use when working with service providers.
There are 2 caching servers in Ho Chi Minh: however, we do not group them into the same location, but separate them into 2 locations (from a CDN logic point of view) because they are hosted at different telcos – Viettel and VNPT. As you can see, there is a 20% difference in speed (latency, measured in ms) even though both servers are hosted in Ho Chi Minh.
Thus, to ensure website owners in Vietnam, and their end users, can reap the speed benefits of CDN, it is important that they are being redirected to the caching server which has the best connection with their local internet providers. This “local CDN” model we deployed puts Vinacis in a great position to grow its new CDN service.
Vinacis – adding Content Delivery to Cloud
Vinacis has been a loyal OnApp customer since 2012, focused on selling compute cloud and storage. In 2013 the company saw an opportunity to add more value to the local market by offering Content Delivery Network services too. Now they’re taking their CDN service to a new level, and the OnApp CDN team started working with them in May this year to create the right solution for their needs.
After spending time with the Vinacis technical, sales and operation team in Ho Chi Minh we quickly reached an understanding of their CDN setup, product and support training requirements, and their sales and operational protocols – as well as the business requirements of their end customers.
Static and streaming content acceleration
VIETNAMCDN is the brand name used by Vinacis for their new CDN offering. The company has already deployed new caching nodes in Ho Chi Minh and Hanoi, replacing its previous nodes, and will ramp up deployment of high performance CDN infrastructure in key locations across the country. To maintain high performance each new server is configured with multiple 2TB enterprise-grade SSDs, and each of them is capable of sustained high bandwidth data transfer.
As well as helping businesses create a low-latency, high performance website experience for static content, VIETNAMCDN has its eye on media content providers who focus in HLS streaming. Its OnApp-based CDN is a highly capable HLS delivery platform: HLS is a widely-used streaming protocol.
Using OnApp CDN and investing in performance hardware has already started to pay dividends: traffic volumes (and therefore, utilization and revenue) increased 50% in the first week the new CDN nodes came online, without any additional sales and marketing activity – an increase in sales that should only get better as VIETNAMCDN starts promoting its services heavily across the region.
Having been immersed in the CDN industry (or I should say Internet) for a great eight years now, I find this project particularly interesting in the way it shows how OnApp CDN offers the flexibility to deal with specific use cases like this, and how CDN adds value for service providers who already offer cloud. It’s also a great example of how we work closely with service providers to understand and deliver what they need to be more successful.
We’re looking forward to supporting Vinacis and VIETNAMCDN into the future. And for all the cloud and CDN providers out there in regions with similar connectivity issues, we’d love to explore how we can build your own “local CDN” with OnApp!
