Why does CDN make sense

Using a CDN service guarantees high availability of all data through a minimal distance between the servers and the customer. The result: shorter data transmission paths, less access to a large number of high-performance servers - and thus a faster experience for the customer.

But it is not only in the case of volume-heavy offers such as video, audio or live streaming where it makes sense to provide the end user with content in the best possible quality and with short loading times via a streaming CDN.

Caching CDNs can also be used to store all other relevant data of a company, such as the website, documents and images, as duplicates at several strategically relevant locations around the world. This means that they are available to every user via a short data path.

The primary goal of content delivery networks is therefore to increase the speed of data provision on the Internet. At the same time, a CDN also helps to provide data without interruption. This high availability is especially important for companies that generate all or a relevant part of their sales on the Internet.

After all, any downtime here is directly associated with a loss. Content Delivery Networks can provide effective protection against DDoS attacks in particular, which can bring servers to their knees with enormous simultaneous data queries.

The «attack load» is distributed among the replica servers and thus reduced for each individual system: the service remains available.
