How does a CDN work

Creating content that people want to read, watch, listen to and share is tough – but getting it in front of those potential audiences can be even harder. After all, if they can’t find your site or app, how are they ever going to see it? Content Delivery Network services (or CDN for short) are a type of web optimization service offered by third-party vendors. These solutions help you get your content in front of the right eyeballs by distributing copies of your files over a wide network of servers that decrease latency, speed up load times and generally make everything as easy to access as possible for users no matter where they are. Effective CDN services can significantly improve performance and user experience for visitors on your website or app, so let’s take a look at what they are, why you need them and which ones are best for different types of businesses.

 What is a Content Delivery Network?

A Content Delivery Network is a distributed network of servers that store and distribute cached copies of your website or app’s content. These servers are strategically placed at points around the world to reduce latency and improve performance of that content for end users. There are two main types of CDN service: “Edge” and “Origin”. Edge CDNs store a cached copy on their network of servers and then serve it up to the user. “Origin” CDNs store a cached copy of your content on their network, but then also communicate with your hosting provider to make sure the most up-to-date version of your files is served to the user.

Why Use a Content Delivery Network?

A video CDN service is an excellent choice for any business that needs to optimize the delivery of its content. A CDN can make all of your static files (i.e. anything not served by a database like WordPress) more easily accessible to your visitors, no matter where they are based in the world. Caching your content on a CDN server can also help you save on hosting costs by offloading some of the traffic from your own servers. Some CDNs are even free to use (though others are not). Once you’ve set up your account with a CDN service provider, it’s easy to automate the caching process so that your content is accessible to your users with no effort on your part.

How Does a CDN Service Work?

Every time a user accesses a web page or app, the server receives a request to retrieve the content and sends it back to the visitor. The time it takes for the server to respond to the request and deliver the content back to the user is the “response time” – and it’s one of the most important metrics to look out for when analyzing website performance.Any business suffers from a slow-loading website. It is crucial to know about page speed optimization. A faster response time is always better for users, as it reduces the amount of time spent waiting for content to load and increases the chance they will come back to your site. A CDN service will store cached copies of your static assets (images, videos, audio files, etc.) on different servers around the world. This means that when a user requests your website or app, their web browser or app will be directed to the closest server with the cached copy of the file in question. This will decrease the response time and improve the user experience by getting the content to them faster.

 CDN Options for Every Business

If you’re wondering which CDN service is best for your business, there are a few things you can keep in mind when shopping around: Some CDN providers specialize in serving up content for one particular industry, so you might want to select one that has experience helping folks in your industry. You can also consider the different types of CDN services available. Some offer “edge” services, while others offer “origin” services. “Edge” CDN providers store cached copies of your files on their network and then serve them up to the user. “Origin” CDN providers store cached copies of your content on their network and then communicate with your hosting provider to make sure the most up-to-date version of your files is served to the user.

Bottom line

If your business relies on high-quality, timely content to engage and convert customers, then you need a Content Distribution Network service to help you get that information in front of the right eyeballs as quickly and easily as possible. A good CDN can improve performance and user experience by caching static content on a network of servers around the world. And that’s why it’s one of the best investments you can make for your business.
