How a CDN Can Speed Up Your Video Content

Most people have watched at least one  YouTube video, and streaming from this site is never slow. Users expect streaming from any site to be as fast as YouTube browsing, and it can be done with the right infrastructure setup including a CDN implementation.

On-Demand Video Streaming

Deployed video content comes in several different formats. You should decide which one is right for you, and any format that you choose will be compatible with a CDN setup.

The first format is a direct download. This isn’t the most common, because the user must be able to download the video and run it on a local desktop. Short video files aren’t too large, but longer video requires a few gigabytes. A CDN will cache this data and deliver downloads faster than forcing users to connect directly to one origin server.

Progressive downloads are much more popular. When a user requests a progressive download video, the server sends content bit-by-bit. Users are able to view content within seconds of accessing the video page. As the user watches the video, the video is downloaded in the background. If you’ve ever lost an Internet connection while streaming video, you’ll notice that you can continue watching for a few more seconds even after losing connectivity. This is progressive downloading at work.

HTTP streaming is similar to progressive downloads, except this format determines the speed of the recipient’s video player. When resources and Internet speed are low, the player downgrades the size of the download. The content transferred requires fewer bits, and the user can still watch content even with a slower Internet connection. If you’ve ever watched a Netflix video, quality of video reduces when your Internet connection slows down.

With all three off these options, a CDN can help speed up transfer of data. Users connect to a CDN’s edge server that’s closest geographically to the viewer. Using cached content and CDN servers closer to the user will speed up delivery and create high-quality output regardless of the type of video content that you deploy.

Live Video Content

With live video, you won’t be able to cache content but you can still integrate a CDN. Using a CDN, you can increase bandwidth and transfer speeds. The biggest problem with live video is the spikes in traffic to view the content, and you stream direct from your location to the user. Users experience. With a CDN, you can add more bandwidth to the user’s connection and transfer video content at optimal speeds regardless of the amount of traffic that requests live stream video.

Remember that you still need enough server resources on your origin server to store and deliver content to the CDN, but overall implementing CDN resources can increase performance on video content.

Any website owner that wants to host content should use a CDN, and before you think it’s an expensive part of site infrastructure, it’s actually an affordable way to speed up web content including video streaming to your viewers.
