What is colocation?
Colocation is a modern hosting model in which companies house their own servers and IT infrastructure in a professional data center. Instead of operating their own data rooms, they rent rack space, power supply, cooling and network connection from a specialized provider. In contrast to traditional web hosting, companies retain ownership and management of their hardware, but benefit from the highly available and secure environment of the data center.
How colocation works
With colocation, the provider provides the necessary infrastructure, while customers bring in their own hardware. The main components provided by a colocation provider include:
- Secure premises in the data center
- Power supply with emergency power generators for uninterrupted energy
- Air conditioning and cooling for optimum operating temperature of the hardware
- Broadband Internet connection for fast and reliable data transmission
- Physical security systems such as video surveillance and access controls
Customers bring their own servers, storage systems and network components and install them in the rented rack units. They retain full control over their hardware and software, while the colocation provider takes care of the operation and maintenance of the infrastructure. This allows companies to focus on their core competencies while enjoying a stable and secure IT environment.
Advantages of colocation
Colocation offers a number of advantages over operating your own server room or completely outsourcing to the cloud:
Cost savings
There is no need to purchase and operate your own data center. Instead, the costs for electricity, cooling and security are shared with other customers, resulting in considerable cost savings.
Scalability
Companies can flexibly book additional rack units as required. This enables quick and uncomplicated expansion of the IT infrastructure without the need for large upfront investments.
High availability
Professional data centers offer redundant systems for power supply, cooling and network connection. This ensures a very high level of reliability and minimizes the risk of downtime.
Security
Colocation providers implement extensive physical and digital security measures. The servers are therefore better protected than in many in-house facilities, which significantly reduces the risk of data loss or unauthorized access.
Powerful connection
Data centers have broadband and redundant internet connections with low latency. This ensures fast and reliable data transmission, which is particularly important for applications with high network speed requirements.
Compliance
Many colocation providers are certified to relevant standards such as ISO 27001. This makes it easier to comply with data protection regulations and other regulatory requirements, which is particularly beneficial for companies in highly regulated industries.
Focus on core business
The time-consuming maintenance of the data center infrastructure is no longer necessary. IT teams can focus on value-adding tasks and use their resources more efficiently instead of spending time managing hardware and infrastructure.
Who is colocation suitable for?
Colocation is particularly interesting for the following groups of companies:
- Medium-sized and large companies with their own IT department: These companies often have the resources and know-how to benefit from the advantages of colocation.
- Companies with high availability and security requirements: Industries such as financial services, healthcare and e-commerce require a reliable and secure IT infrastructure.
- Companies that want to centralize their IT infrastructure: Colocation enables efficient management and monitoring of IT resources at a central location.
- Providers of cloud and hosting services: These providers require high-performance computing infrastructures to operate their own services and serve customers.
- Companies with special compliance requirements: Companies that have to comply with strict data protection and security regulations benefit from the certified and secure environments of colocation providers.
Colocation vs. other hosting models
Compared to other common hosting models, colocation has a number of special features and advantages:
Colocation vs. on-premise
With the on-premise model, companies operate their servers on their own premises. Colocation shifts this to a professional data center and thus saves costs for infrastructure, maintenance and security.
Colocation vs. dedicated hosting
With dedicated hosting, the provider provides and manages all the hardware. With colocation, the customer brings their own servers and retains more control and flexibility over the hardware and its configuration.
Colocation vs. cloud hosting
Cloud services offer more flexibility and scalability, but often less control over the hardware. Colocation enables the use of specialized hardware and full management rights, which can be advantageous for certain applications and companies.
Colocation vs. managed hosting
Managed hosting involves the full management of the servers by the provider. With colocation, this remains the responsibility of the customer, which enables greater control over the IT infrastructure, but also requires more personal responsibility.
Requirements and challenges when using colocation
The use of colocation places a number of demands on companies that need to be taken into account:
Own hardware
The customer is responsible for purchasing and maintaining the servers. This requires IT expertise and corresponding investment in the hardware as well as regular maintenance and updates.
Remote management
As the servers are not located on site, effective remote maintenance must be possible. This requires suitable tools and a well-organized IT team that is able to diagnose and resolve problems remotely.
Planning of resources
Power consumption and required rack space must be calculated in advance to ensure that the resources provided meet the actual requirements. Precise planning prevents over- or under-utilization of the infrastructure provided.
Security concept
Despite the extensive measures taken by the data center, IT security remains the responsibility of the customer. A comprehensive security concept that includes both physical and digital security measures is essential.
Disaster recovery
Failure scenarios and backups must be planned and implemented in order to be operational again quickly in the event of an emergency. A well thought-out disaster recovery concept minimizes downtime and the loss of important data.
Contract design
Service level agreements (SLAs) and liability issues should be carefully checked to ensure that the services offered meet your own requirements and that clear regulations are in place in the event of an emergency.
Colocation costs
The costs for colocation are made up of several factors:
- Rack rental: The price per occupied rack unit is usually calculated on a monthly basis and depends on the size and location of the data center.
- Electricity costs: These are billed according to actual consumption and can vary depending on the power requirement.
- Network connection: The costs for guaranteed bandwidth depend on the required speed and the number of connections.
- Setup fees: One-off costs for installing and setting up the hardware in the data center.
- Additional services: Options such as hands-on support, extended monitoring or additional security measures may incur additional costs.
The exact prices vary greatly depending on the provider and scope of services. Compared to an in-house data center, however, the overall costs can be significantly lower, as many fixed costs are shared and scaling can be more flexible.
Selection of a colocation provider
When choosing a suitable colocation partner, companies should pay attention to the following aspects:
Location
The geographical location of the data center influences latency times and can have legal relevance. A location close to your own business premises can offer advantages in terms of speed and accessibility.
Certifications
Industry standards such as ISO 27001 or the TÜV seal provide information about the quality and security of the data center. Certified providers ensure that high standards are maintained.
Connectivity
The number and quality of network connections are crucial for performance and reliability. A provider with multiple and redundant connections ensures that the Internet connection is stable and fast.
Scalability
The provider should offer opportunities for growth without the need to relocate. Flexible contract models and the ability to add additional resources quickly are important here.
Support
Competent technical support that is available 24/7 is essential. Fast response times and expert support make a significant contribution to the stability of the IT infrastructure.
Additional services
Options such as remote hands service, backup solutions or extended monitoring options can increase the added value of the colocation offer and should be considered when choosing a provider.
Contract conditions
Flexible terms and fair SLAs should be standard. Contracts should contain clear regulations on performance, availability and support in order to avoid misunderstandings later on.
References
Testimonials from other customers provide information about the reliability and service quality of the provider. Positive references are a good indicator of the satisfaction of existing customers.
The future of colocation
Despite the ongoing trend towards the cloud, colocation remains relevant for many companies and continues to evolve. Future trends and developments include:
Hybrid infrastructures
The combination of colocation, private cloud and public cloud is becoming increasingly common. Hybrid infrastructures offer the flexibility of the cloud and the control of your own hardware, which is the optimal solution for many companies.
Edge Computing
Colocation providers are increasingly positioning themselves as locations for edge data centers. This enables faster data processing and lower latency times, which is particularly important for applications such as IoT and real-time data processing.
Sustainability
Efficient large data centers contribute to reducing the carbon footprint of companies. Many colocation providers are increasingly focusing on renewable energies and energy-efficient technologies in order to operate more sustainably.

Computing-intensive applications such as AI and HPC require specialized hardware and high-performance infrastructure. Colocation offers the optimal environment for operating such applications, as powerful data centers can provide the necessary performance and cooling.
Data sovereignty
Colocation gives companies more control over their data compared to many cloud solutions. This is particularly important for companies that need to keep their data within certain geographical boundaries or meet specific data protection requirements.
Conclusion
Colocation offers companies an attractive way to operate their IT infrastructure professionally and cost-effectively. It combines the advantages of own hardware with the reliability and security of a modern data center. For many companies, colocation is therefore an important building block in their IT strategy - whether as the main solution or as part of a hybrid infrastructure.
The decision for or against colocation depends on a company's individual requirements and resources. A careful analysis of one's own needs and a comparison of different hosting options are essential to find the optimal solution. However, with the right partner, colocation can lead to significant cost savings, improved performance and greater security, enabling companies to strengthen their competitiveness and make their IT more efficient.
