Alleviating and accelerating your environment

Attractive and simple price model

Together with our partners, we provide you with leading CDN solutions to quickly deliver your data anywhere in the world. This gives you low latencies and reduces the load on individual systems in order to achieve optimal performance for your customers. The Premium Business CDN offers you an attractive price per GB - regardless of the region to which the data is delivered.

What is a CDN?

A content delivery network, or content distribution network (CDN for short) is a globally distributed network for relieving the load on and accelerating your hosting environment. Other servers (replica servers) are used in addition to the servers (origin servers) of the central hosting platform. These replica servers are distributed at strategic positions on the Internet and are called CDN nodes.

The data from the origin servers is cached at the CDN nodes. This significantly reduces the geographic proximity of the end user to the CDN nodes, as well as the latency between clients and servers and the load on the main platform. Because of the distributed storage locations of the data, the term ‘Cloud Delivery Network’ is often used.


  • Regional traffic delivery
  • Acceleration of the hosting infrastructure
  • Relief of the load on the server platform
  • SSL (optional)
  • Needs-oriented solution model: Premium Business CDN, Individual CDN
  • Administration by customer possible
  • Pay-per-use billing

Classic environments vs. CDN

Diagram Difference without CDN and with CDN

While classic environments are set up so that each user, regardless of their location, communicates with the same target system, data in a CDN is always passed on by the nearest CDN node. This manifests itself in a significant improvement in performance.

Product variants

We offer two CDN products: Premium Business CDN and Individual CDN. The Premium Business CDN is ideal for delivering classic web content (static content such as text, images, download material, etc.), whereas the Individual CDN is the first choice when it comes to static and dynamic content. It is suitable for live events or streaming larger media files (video/audio portals).

Premium Business CDN

A fair price for all regions

Premium Business CDN is a tailored planned un/encrypted caching CDN product. The configuration is planned in consultation with you and in line with your wishes. At least the CDN nodes in North America and Europe will be used. Furthermore, the Asia-Pacific region (excluding China) and the Latin American region can be used. On request, you can add your own SSL certificate. The service is only billed for what you use and you will receive the same low price for each region (APAC and LATAM up to max. 30 percent of the total traffic).

  • Customised, unencrypted/encrypted
  • Customer-specific configuration
  • Transmission to the US and EU; APAC optional
  • Customised/neutral supername
  • Own SSL certificate possible
  • Usage-based payment, simple billing

How a CDN works

Your advantages

  • Cost optimisation through lower bandwidth consumption
  • Performance optimisation (higher data transfer speeds)
  • Reduced risk of DDoS attacks


  • Origin server
  • Replica server
  • User

Because the data is stored at key points, a distribution system is created to manage the x number of origin servers and respond to a high number of requests.

In addition to the technical advantages, a CDN also reduces the threat of DDoS attacks, as these are distributed worldwide and do not affect just one single environment. As less bandwidth is used, the relevant costs can also be cut. PlusServer works together with reputable CDN providers, who provide you with your high-performance backbone.

DDoS Mitigation

Do you want additional security?

Performance and availability determine your business success. So don’t just deliver your data quickly to your customers, employees or business partners. Protect your environment from downtime caused by DDoS attacks. We are happy to advise you on the right DDoS protection for your needs.
