By caching content on CDN servers, the origin server does not have to serve every request, which results in a lower load and improves scalability. The origin server is less susceptible to overload, especially with high data traffic.

CDNs use technologies such as HTTP/2, edge computing and minification to load content faster. This improves the user experience and can reduce the bounce rate, which is particularly important for websites with high performance requirements.

Many CDNs support the optimization of content for different screen sizes and resolutions. For example, images can be automatically adjusted and videos can be provided in the correct resolution to minimize loading time and bandwidth usage.

CDNs often offer integrated security functions such as web application firewalls (WAF) and DDoS protection to intercept attacks and protect the origin server. Due to its distributed structure, a CDN can filter requests better and distribute the effects of an attack.

As content is distributed on several servers worldwide, availability is maintained in the event of a server failure. CDNs can automatically redirect requests to other PoPs if a server fails, which increases reliability.

cDNs offer effective load balancing by distributing requests to different servers. This means that even high data traffic peaks can be better processed without creating bottlenecks.

The improved loading speed and user-friendliness have a positive effect on search engine rankings, as search engines such as Google prefer fast loading times and a smooth user experience.

CDNs store copies of web content such as HTML pages, JavaScript files, stylesheets, images and videos on their servers. When a user accesses a website, the content is served from the nearest CDN server instead of the original hosting server

CDNs distribute data traffic across several servers in order to avoid overloading individual servers and increase the availability and reliability of services. This ensures even load distribution and prevents bottlenecks.

The proximity of the CDN servers to the end users reduces network latency. This leads to faster response times and an improved user experience, especially for large or highly frequented websites.

CDNs enable simple scaling of web services by distributing the data traffic across many servers. This is particularly important for sudden peak loads, such as those that can occur during large events or viral content.

Many CDNs offer integrated security functions to protect against Distributed Denial of Service (DDoS) attacks. They can absorb and filter large volumes of malicious traffic before it reaches the origin servers.

CDNs support the provision of encrypted content via SSL/TLS, which increases the security and trustworthiness of web services. This protects the data during transmission between the CDN and the end users.

CDNs provide tools to monitor and analyze traffic to gain insight into usage patterns, performance and potential problems. This helps to optimize the efficiency and effectiveness of the CDN.

CDNs protect the origin servers by intercepting and processing the majority of data traffic. This reduces the load on the origin servers and increases their service life and performance.
