To deliver web information to a user based on their location, a system of dispersed servers is known as a content delivery network (CDN). High availability and high-performance content delivery to end users is the aim of a CDN. A request for material is routed to the CDN server that is nearest to the user because CDN servers are spread across several data centers across the globe.
Content such as web pages, movies, photos, and software downloads can all be delivered using CDNs. Large websites and online businesses frequently use them to lighten the load on their servers and enhance the visitor experience. CDNs can also be used to boost content availability and defend against DDoS attacks.
Additionally, CDNs can be utilized to enhance website security. To aid in the defense of websites from malicious assaults, several CDN providers provide features like SSL/TLS encryption, DDoS mitigation, and Web Application Firewall (WAF) services.
By utilizing methods like caching, compression, and minification, CDNs can also aid in enhancing the performance of websites. To quickly distribute the material to users without having to repeatedly request it from the origin server, caching includes keeping a copy of frequently requested content on the CDN server.
Compression helps to minimize the size of the material being given, which can assist to speed up load times and decrease the quantity of data that needs to be transferred. Whitespace and extra characters are removed from code during minification, which can also aid to minimize the size of the content being delivered.
Another advantage of CDNs is that they can assist in distributing the traffic load across many servers, increasing the availability of content during periods of high traffic. This is especially helpful for heavily trafficked websites, such as e-commerce sites, media websites, and websites for online gaming.
