Data centers are the digital backbone of our time. They store, process, and transmit data – enabling virtually all digital applications we use today as a matter of course: from cloud services and e-commerce to streaming, mobility, and artificial intelligence, all the way to managing critical infrastructure.

The importance of data centers can also be expressed in numbers:

Currently, there are about 1,994 data centers in Germany – over 300 of which are in the colocation sector. The market is growing rapidly: The installed IT capacity of German colocation data centers is expected to more than double from 1.3 gigawatts (GW) in 2024 to over 3.3 GW by 2029. Economically, the industry is also a heavyweight: Data centers contribute about 10.4 billion euros annually to Germany’s gross domestic product (GDP) – with an upward trend (Source: German Datacenter Outlook 2024/25 by the German Datacenter Association).

But what exactly is a data center? How does it work? What technologies are behind it? And why are topics like sustainability and energy efficiency increasingly coming into focus?
