What are Content delivery networks (CDNs)
A content delivery network (CDN) is a large distributed system of servers that delivers web content to a user based on the geographic location of the user and the origin of the web content. Not all websites use CDN services, but many high-traffic sites do. Facebook, Yahoo, Amazon, Baidu, Twitch, Tumblr, and Netflix are some examples of popular websites that use CDNs.

Our CDN servers are backed by 24/7 expert support and guaranteed performance and scalability. We offer managed services to take care of everything from network connectivity to server maintenance and backups.
An important advantage of using a CDN is that it reduces bandwidth costs for the operator of the Web site. This is particularly true if the Web site originates much of its content in one location and users are scattered across the globe. It also reduces latency times for end-users, especially users located far away from the Web site's origin server.
Content delivery networks (CDNs) are the backbone of the internet. They're immensely complex, but they're also vital to how we all use the web. CDNs are essentially just a network of computers that store copies of the content. Some are owned by companies like Google and Amazon, while others are rented from hosting providers.
How do CDNs help you?
Well, CDN technology is designed to speed up websites by reducing lag time. It caches content on servers around the world so that when your users request data, it's instantly available to them without any delay. When CDN technology is used effectively, there's no more waiting for images to load or videos to buffer. If you have a high-traffic site or business, these benefits can be critical for your bottom line.
What are the different types of CDN?
The most common are the following:
1) Global Content Delivery Network (or Global CDN) is a service that allows users to upload their content to the cloud and host it on servers located in multiple countries.
2) Content Delivery Network (or CDN) is a service that allows users to upload their content to the cloud and host it on servers located in multiple cities.
3) Caching/Proxy Server is a type of network storage where frequently accessed information can be temporarily stored instead of having to be requested from the original location each time.
4) Local Content Delivery Network (or Local CDN) is a service that allows users to upload their content to the cloud and host it on servers located in multiple buildings.
Uses of Content Delivery Network (CDN)
Since these are networks of servers distributed across multiple locations, which serve as a repository for the static content of the websites.
1) The CDN distributes copies of this static content like HTML pages and images and helps in delivering high-bandwidth content to the nearest location of the user requesting it.
2) CDNs deliver various kinds of content like media files (audio/video), web applications, live streaming media, and software.
3) A powerful CDN will not only improve response times but also reduce bandwidth costs by serving cached copies of files from locations close to the end-user.
4) You can have unlimited bandwidth and give more bandwidth to users.
5) Security is improved by making the website less attractive to hackers.
6) Hosting options are increased since CDN caches static content at the edge locations, the location logically closest.
7) Minimize latency (TTL) by decreasing the distance between end-user and content source (faster response times) and. maintaining data integrity between cache locations.
8) Better user experience for global audiences by increasing website uptimes.
9) Increasing the availability of content and improving page performance, conversion rates, and the speed of websites.
10) Global CDN eliminates file size issues with international users to reduce server loads.
Tips while Setting Up CDNs
1) Make sure your CDN is not blocking you.
2) Do not rely on Origin Pull or Cache-control Plugin
3) Avoid downtime by using CDN with multi-regional DNS setup
4) Use Cookies_First Caching Model
5) Configure CDN to cache for one year
6) Use HTTP/2 protocol with your CDN
7) Test your site on different servers
8) Make sure your site will still work after switching off caching.
9) Buy a good quality domain
10) Use HTTPS and secure protocols
11) Check all links include your CDN files
12) Run your CDN through a series of tests and test your CDN on mobile devices
13) CDN like Cloudflare will Help Prevent DDOS Attacks
14) Do not use flash or video on your website with a CDN unless you have no other option.
15) Reduce render‐blocking JavaScript and CSS.
