Large websites and video portals contain many large files - images, video and audio. This is content that is important for the user to receive in a timely manner, without delays and errors. Previously, compression was used to speed up loading, but today the problem of access to high-quality files is solved by CDN networks. They allow you to place website content on servers closer to the end user. Let's consider this process in more detail in this article.
Briefly about CDN
CDN or Content Delivery Network is a geographically distributed structure of server networks. It allows optimizing the delivery of large data ( mainly video, audio, images ) to Internet users. This is done by placing content on servers located closer to consumers.
The global network consists of data transmission channels. To connect them together and provide wordpress web design agency access to files on servers, various node equipment is used: routers, hubs, etc. Each such device processes the flow of requests, respectively, the further the server is from the user, the slower and more unstable the video loads.
Connecting to a CDN allows content owners to automatically distribute their data to storage locations that will be the shortest path for key consumer groups. Not only in terms of mileage, but also with the fewest steps to the destination.
Getting data from a server without CDN
Here you can see how accessing data from a server without a CDN works. Before the request reaches the endpoint, it will pass through a whole network of devices.
Data distribution using CDN
When using CDN-based data distribution, each user gets their own, faster route to the destination. Simply put, a viewer from Vladivostok will download a video from a server in, say, Khabarovsk, if it is originally hosted in a Moscow data center and the service is connected to a CDN.
At the same time, the technology not only helps a specific user, but also relieves networks and data transmission channels, optimizes content ( video, audio, images ) on websites, reduces the load on servers and network nodes, and increases its throughput.
CDN services are provided by the corresponding providers, today in Russia there are already quite a lot of them. To connect sites to the content delivery network, you need to conclude an agreement with the provider, set up access to the service control panel and configure your domains to work in the network.
CDN for delivering video and visual content
The study showed that 40% of viewers stop watching a video because of its frequent loading ( buffering ). At the same time, the large number of options for where this video can be watched leads to an outflow of users from the video hosting.
