Twin-core principle and georedundancy

With our twin-core data centers providing separate availability zones (AZ) in Germany, the Netherlands and Switzerland, we can offer high availability for the European region and guarantee secure and reliable cloud services.


In addition, our data centers meet all recommendations of the German Federal Office for Information Security (BSI) regarding georedundant data storage, ensure maximum availability and fail-safety. Their distance safeguard service availability in the event of natural disasters or other failures. Our data centers exceed BSI requirements with up to 500 kilometers between sites.


The advantages of the twin-core and georedundancy approach are apparent: data is stored in multiple versions on request, and even in the event of the complete failure of a data center or an entire region, operations are secured. The data centers in Magdeburg/Biere form the EU-DE region, the data centers in Aalsmeer/Almere the EU-NL region. The two areas are connected by default via a high-speed network. The Swiss Open Telekom Cloud in Bern/Zollikofen is available as a completely self-sufficient community cloud and can be linked to the other regions if required.

Cloud resilience and shared responsibility

Ensuring high performance and reliable services is one of the main requirements of cloud infrastructure. Failures and downtimes jeopardize business operations. They consume time, money and reduce end user satisfaction. Therefore, effective business continuity management that protects systems and infrastructure against attacks and disruptions is essential.


It is important to bear in mind: In a public cloud, the principle of “shared responsibility” applies. This means that it is clearly defined which measures are the responsibility of the provider and which are the responsibility of the customer. This means that the operation of services in a cloud is a matter for both the provider and the customer.
