What does Hetzner actually do?

Discover our world and learn more about our core business.

At Hetzner, we work every day with technologies that power our digital world – from powerful servers to state-of-the-art data centers. But we also have positions that are not directly related to our core business. We want everyone to understand what makes us special as a company, even without any technical knowledge.

What is a server?

A server is a powerful computer that stores data and programs and makes them available to other devices. It functions as a central hub through which information is shared and processed. Whether it's websites, emails, or files, all of this is stored on servers and can be accessed by other computers. Servers run around the clock to ensure that data is available at all times. They form the technical basis for the internet and many digital services that we use every day.

What is a data center?

A data center is a building or specially equipped room that houses many servers. These servers operate around the clock, ensuring that data is stored, processed, and made accessible securely. Data centers have special measures in place for power supply, cooling, and security to ensure that the servers function reliably. Data centers are therefore the places where the digital services and information we use every day are physically stored and managed.

Why are things in the cloud?

Cloud servers are virtual servers that run on physical servers in data centers. They can be created in seconds and flexibly customized – for example, with additional storage, private networks, or IP addresses. What makes them special is that cloud servers offer scalable computing power that can be used as needed without having to operate your own hardware. They are reliable and available at all times, so data and applications can be accessed from anywhere. You only pay for what you actually use – an efficient and inexpensive solution for flexible requirements.
