Building A Video-Streaming App: A Review of LeaseWeb’s CDN

I’ve had an idea for a while to create a mobile app that would enable people to easily find and view films that are part of the public domain. Many of these movies have substantial historical significance.

Of course, because of the size of these movies, generally players can’t simply download all the videos, but rather must download them on demand, or even better: stream them smoothly.

The best way to accomplish this is use Apple’s HTTP Live Streaming (HLS), which is automatically integrated into iOS’s video-playing APIs.

But where to host these files becomes the next architectural issue to tackle when designing the end-to-end functionality of such an application.

Scalability isn’t generally the first thing you think about when you create a website or an application. However, if you are planning for the future, or when you start to run into scalability issues, making sure that your static content (images, videos, etc.) is served from a cache rather than a server’s file system is essential to creating a set of happy users.

The obvious choice is to serve the videos from a super-fast Content Delivery Network (CDN) that is optimized for serving up videos.

LeaseWeb’s CDN is exactly the kind of CDN that I’d choose for this kind of application. LeaseWeb’s CDN has a number of unique features that make it the right choice for any number of different CDN-based solutions, but it has a special set of features that makes it a particularly good choice for building video-based applications.

One of those features is its superior bandwidth. LeaseWeb CDN has capacity of 500 GBps and growing, thanks to the placement of what they call SuperPoPs around the world (remarkable for a product that has been on the market for less than a year).

For large file distribution, like video, bandwidth is a more important measure for CDNs than latency. Large and consistent bandwidth can make (or break) the video viewing experience in an app or webpage. Buffering during the middle of watching a movie is a quick way to get customers to stop using your app, give you bad reviews, or both.

LeaseWeb CDN’s superior network bandwidth, along with its low latency due to edge server locations in Europe, US, and Asia, makes it a perfect choice for global video-based applications.

On top of the infrastructure, LeaseWeb also has a sophisticated HTML5-based CDN Control Panel that takes away the complicated configurations that most Content Delivery Networks have.


The CDN Control panel not only has a dashboard that can show you your bandwidth usages in real time and historical information about your traffic, it also has all the functionality necessary to completely manage your Pull and/or Push Zones. Your configuration can be fully managed through this UI, but is also accessible via an easy-to-use API.


The CDN has support for static files (including video), as well as support for HTTP Live Streaming, or Video on Demand HLS.

Using a Pull Zone is an easy way to keep your content on your servers, and allows the CDN to push your content out to its edge servers in its data centers around the world.

Because the video content is already hosted in LeaseWeb’s data centers, this makes using LeaseWeb’s Cloud Server for hosting login and other API functionality a natural choice.

Putting all of your content in one place, and having that place take advantage of LeaseWeb’s fast virtualized computer resources as well as the fast connection between those computer resources and the CDN, make it the perfect pairing, especially for dropping new video files, or processing on those files.  Having your content and your cloud-based server functionality all in one place means that functionality will be as fast as possible.
