Trusted Advisor for IT & Telecommunications Sourcing
Colocation as the answer to complex IT infrastructures
How to make IT infrastructure modern, flexible and economical
Colocation consulting from SAVECALL Consulting
In an increasingly digitalized world, data centers have become an indispensable part of the global IT landscape. However, companies are faced with the challenge of having to operate on-premises data centers with ever-increasing effort and costs.
Auf den Punkt gebracht:
- Significant cost savings through shared resources
- Access to certified experts and state-of-the-art technology
- Operational efficiency through scalable and flexible solutions
- Risk minimization thanks to highly secure data centers
- Compliance & security according to international standards
Die Lösung: Colocation offers the ideal solution here: instead of operating their own data centers at great expense, companies outsource their IT hardware to highly secure external data centers. This reduces complexity, costs and risks and creates space for innovation and growth. The SAVECALL promise: We support you in choosing the right colocation partner and ensure maximum efficiency, security and sustainability.
Worum es in diesem Beitrag geht: How can companies make their IT infrastructure modern, flexible and economical at the same time? This article looks at six key advantages of colocation and what matters when choosing the right partner.

Cost savings
Building and maintaining an on-premises data center incurs enormous investment and operating costs. Colocation reduces this burden considerably, as companies use the infrastructure of a professional service provider.
- No high investments in own data centers
- Release of capital for strategic initiatives
- Avoidance of losses due to downtime & security incidents
- Improved energy efficiency (PUE) through modern technologies, AI & machine learning
Germany’s Energy Efficiency Act (EnEfG), in force since September 2023, makes this advantage measurable: new data centers must achieve a PUE of no more than 1.2 from July 2026, with existing facilities following by 2030 at staggered limits of 1.5 and then 1.3. According to the Uptime Institute, the global industry average currently sits at around 1.5, a level many older on-premises data centers do not reach.
Scalability as required
Growing or reducing IT capacities is no problem with colocation. Companies can flexibly adapt their infrastructure without having to invest in new hardware or space.
- Additional racks, network connections & cloud on-ramps are available immediately if required
- No interruption to business operations thanks to flexible scaling
Improved data security
Colocation providers rely on comprehensive security measures, both physical and organizational. Companies benefit from protection on several levels, from access control and video surveillance to early fire detection and multi-layered security concepts. Additionally bookable managed security services offer enhanced protection and help reliably meet compliance requirements.
Service Level Agreements (SLAs)
Transparency and reliability are crucial when it comes to operating business-critical IT systems. Colocation providers assure companies of binding standards for service quality and response times. This gives IT departments the necessary planning security and enables them to reduce risks in a targeted manner.
- Guaranteed availability
- Regular reports & monitoring
- Clear processes and sanctions for non-compliance
In contrast to purely internal IT teams, colocation providers offer SLAs that are measurable and verifiable: a clear advantage for companies with high compliance and security requirements.
Reliability & business continuity
Companies secure their processes with redundant systems, contingency planning and the expertise of colocation providers. This effectively reduces risks and outages. The providers’ experience ensures that resources can be scaled efficiently and problems are proactively identified before they affect business operations. This ensures a stable and uninterrupted IT infrastructure that remains reliable even in critical situations.
Continuous technological progress
Colocation means access to innovations without having to make your own investments. Providers make state-of-the-art technologies available and carry out regular upgrades so that companies always benefit from the latest developments.
- Direct cloud connections & private connections
- Regular infrastructure upgrades
- Access to cutting-edge technology and flexible integration options
Like all modern IT strategies, colocation combines local systems with the cloud, for maximum resilience, future-proofing and seamless integration into existing business processes.
Important selection criteria for colocation partners
Companies looking for a service provider for their data center should base their decision on individual business goals and digital priorities. It is not enough to simply check the minimum criteria, the decisive factors are those that create real competitive advantages.
- Hyperscale partnerships for maximum scaling
- End-to-end managed services for multi- and hybrid cloud environments
- Interconnect services for locations and partner ecosystems
Colocation is therefore a valuable strategy for making optimum use of IT resources and remaining competitive in a rapidly evolving digital world.

Frequently Asked Questions
Frequently Asked Questions about Colocation
With colocation, companies place their own IT hardware, such as servers, storage and network equipment, in an external data center run by a specialized provider. The provider supplies space, power, cooling, security and network connectivity, while the company remains the owner and operator of the hardware. This is what distinguishes colocation from hosting, where the hardware itself is also rented.
With colocation, the hardware still belongs to the company, only the location is outsourced. With hosting, the company also rents hardware and software from the provider. Cloud solutions go a step further and provide computing power fully virtualized and on demand. In practice, many companies combine all three models depending on the use case.
The Energy Efficiency Act (EnEfG), in force since September 2023, requires data centers in Germany to meet staggered PUE limits: new builds from July 2026 must achieve a PUE of no more than 1.2, while existing facilities follow by 2030 with limits of 1.5 and then 1.3. Many older on-premises data centers do not meet these values, whereas modern colocation providers often already do, which also gives the choice of a certified partner regulatory backing.
Recommended certifications include ISO 27001 for information security, complemented by ISO 9001 or recognized TIER classifications for infrastructure availability. Physically, access control, video surveillance, early fire detection and redundant power supply with UPS systems and backup generators should be in place. Additionally bookable managed security services help reliably meet compliance requirements.
Important factors are measurable and verifiable standards for availability, response times and maintenance windows, complemented by clear processes and sanctions for non-compliance. Regular reports and monitoring give IT departments the necessary transparency. Compared to purely internal IT teams, specialized colocation providers generally offer more robust, contractually fixed guarantees here.
Besides cost and security certifications, hyperscale partnerships for scalability, end-to-end managed services for multi- and hybrid cloud environments, and interconnect services to locations and partner ecosystems are decisive factors. A vendor-neutral comparison helps find the partner that fits individual business goals and digital priorities, rather than one that only meets minimum criteria.
