What is a data center? Origin, structure, function, and further development

Data centers are the backbone of our digital world and play a crucial role in the storage, processing, and transmission of data. In this article, we take a look at the history of data centers, their structure, function, and developments in recent years, particularly in terms of scalability, energy efficiency, and cost reduction.


The history of data centers dates back to the 1940s, when the first computers were developed. At that time, computers were still room-filling machines mainly used for military and scientific purposes. With the advancement of computer technology and the introduction of mainframe computers in the 1960s, the first data centers were established to house these devices and provide the necessary infrastructure. In the following decades, data centers continued to evolve to meet the growing demands for data processing, storage, and communication.

The structure of a data center

A data center is essentially a large, climate-controlled facility that houses servers, storage systems, and network infrastructure. The main components of a data center include:

  1. Servers and storage systems: These are where data is processed, stored, and transmitted. Servers can be physical in the form of rack or blade servers or virtual in the form of virtualized servers.
  2. Network infrastructure: This includes switches, routers, and other devices that enable communication between servers and the internet or internal networks.
  3. Power supply: Data centers require reliable and uninterrupted power to ensure continuous operation. This includes backup generators, uninterruptible power supplies (UPS), and redundant power circuits.
  4. Cooling: Since servers and other IT equipment generate a lot of heat, effective cooling is crucial. This includes air conditioning systems, ventilation systems, and potentially innovative cooling technologies such as liquid cooling or free cooling.
  5. Security: To ensure the protection of data and infrastructure, data centers are often equipped with physical and digital security measures such as access controls, surveillance cameras, fire suppression systems, and more.

Function of Data Centers

Data centers serve the centralized storage, processing, and transmission of data. They are essential for a variety of applications and services, such as cloud computing, web hosting, big data analytics, artificial intelligence, email servers, and much more. Companies and organizations of all kinds use data centers to manage, secure, and access their IT infrastructure. Additionally, data centers enable the scaling of IT resources and the provision of flexible, cost-effective solutions for a wide range of requirements.

Scalable modular data centers, the future of flexible and sustainable data infrastructure

An important trend in the data center industry is the development of scalable, modular data centers. These modular data centers offer a flexible, cost-effective, and environmentally friendly alternative to traditional, monolithic data center solutions. In the following paragraph, the advantages of modular data centers and their importance for the future of data infrastructure are explained in more detail. One of the greatest strengths of modular data centers is their scalability.

Unlike traditional data centers, which often have a fixed size and capacity, modular data centers can easily be expanded or reduced by adding or removing modules. This allows companies to tailor their IT infrastructure precisely to their current and future needs and avoid unnecessary investments in unused capacity. Additionally, the flexibility of the modular design allows for faster adaptation to new technologies and market conditions.

Modular data centers can offer significant cost savings compared to traditional data centers. Since the modules are prefabricated and standardized, they can be produced, delivered, and installed more quickly and cost-effectively. Furthermore, modular data centers can be expanded in smaller, more cost-effective increments as needed, reducing overall investment costs. Moreover, modular data centers are often more energy-efficient than traditional data centers, leading to lower operating costs and a smaller environmental footprint.

The modular construction of data centers makes it easier to integrate energy-efficient technologies and sustainable materials. For example, since the modules are prefabricated, they can be equipped with efficient cooling systems, renewable energy sources, or even free cooling to reduce energy consumption and environmental impacts. Additionally, modular construction allows for the reuse of modules and materials, further reducing the overall environmental impact.

Since modular data centers are prefabricated and standardized, they can be deployed and operational more quickly than traditional data centers. This is particularly important for companies that need to quickly respond to growing IT requirements or market changes.

Overall, scalable modular data centers offer a future-oriented solution for the growing demands on data infrastructure. Through their scalability, flexibility, cost efficiency and environmental friendliness, they enable companies to expand their IT infrastructure in a sustainable and efficient manner and to adapt to the constantly changing market conditions. In view of increasing digitalization and the growing importance of cloud computing, Big Data and IoT applications, the importance of modular data centers will continue to grow.

Another advantage of modular data centers is their improved resilience and redundancy. Since they consist of multiple independent modules, in the event of disruptions or failures in one module, they can maintain the operation of the remaining modules. This increases the operational reliability and availability of the IT infrastructure and minimizes downtime and data loss.

The modular design also enables better adaptability to different geographical and climatic conditions. Depending on the location and environmental conditions, different modules and technologies can be used to ensure optimal operating conditions and energy efficiency. This can be particularly important in areas with extreme temperatures or high humidity levels, for example.

Finally, modular data centers also allow for a decentralized infrastructure, which is particularly beneficial for edge computing applications. By distributing data centers close to data sources and users, latency can be reduced and network loads minimized. This is particularly important for time-critical applications and services, such as autonomous driving, real-time monitoring or Industry 4.0 applications.
