For many small companies, keeping a server in the office is a perfectly practical solution at first. Over time, however, maintaining it can become more difficult. Cooling may no longer be sufficient, power may become unreliable, available space may shrink, and security requirements may increase.

At that point, this type of service becomes a realistic alternative. The company keeps its own hardware and remains in control, but moves the equipment into a professional data center where the required physical environment is already in place.

In this article, we will look at when this model makes sense for a small business, what costs it involves, and when another hosting option may be more suitable.

How Does It Work in Practice?

With colocation, a company moves its physical servers out of the office and into a professional data center without giving up ownership. The provider supplies rack space, power, cooling, network connectivity, and physical security.

This does not mean the provider takes on all responsibilities. Unless managed services are included, the business still administers the operating system and applications, monitors server performance, applies updates, maintains backups, and responds to hardware issues.

In practice, the responsibilities are clearly divided. The data center manages the physical environment, while the company retains control of its equipment and systems. This distinction matters because moving a server out of the office does not eliminate the costs and responsibilities of owning it.

Does It Make Sense to Move Your Existing Hardware?

If the company already owns a reliable, sufficiently powerful server, moving it to a data center may be more sensible than buying new infrastructure. However, assess the equipment's condition first. A server that is near the end of its useful life, no longer under warranty, or likely to need major component replacements soon may not justify the cost of relocation.

Check performance, disk health, replacement-part availability, and when the next hardware refresh is expected. Its purpose also matters. Specialized storage systems, GPU equipment, or custom network configurations give the company a stronger reason to retain ownership and physical control of the machines.

Before comparing colocation prices, consider whether the existing hardware has enough remaining life and value to justify moving it and using it for several more years.

Practical Example

Imagine a small company using two three-year-old servers for its internal systems and customer-facing applications. The machines still meet the business's requirements, have enough capacity for the next several years, and replacement parts are readily available.

If the office can no longer provide reliable cooling, backup power, or the required level of physical security, buying new servers does not solve the underlying problem. In that case, moving the existing equipment to a colocation facility may be the more sensible investment. The company continues to use hardware it already owns, but places it in an environment designed for long-term operation.

How to Calculate the True Cost of Colocation

What Does the Data Center Fee Include?

The price can include different services depending on the provider. Typical charges include rack space, power, network connectivity, IP services, and remote hands support. In some cases, providers may also charge separate fees for initial installation, cross-connects, or other services.

Which Costs Remain With the Company?

Moving the server into a data center does not eliminate the costs of owning the equipment. The company still incurs costs for hardware, warranties, replacement components, software, backups, monitoring, administration, security, and future upgrades.

This is why the monthly colocation fee is only one part of the total cost. A realistic calculation should also include all expenses required to keep the server reliable and properly maintained throughout its useful life.

Compare the Total Cost, Not Just the Monthly Fee

The most useful metric is total cost of ownership (TCO) over the expected hardware lifespan. Instead of comparing only the monthly colocation fee with the price of a cloud service or dedicated server, compare the full cost of both models over several years.

The calculation should include hardware purchase and future replacements, electricity, maintenance, administration, and any additional services. This provides a much more realistic view of which option is more cost-effective in the long term.

Who Takes Care of the Server After It Is Moved?

What Still Falls to Your Team?

Colocation does not automatically include server administration. Unless you have contracted managed services, your team remains responsible for the operating system, applications, updates, monitoring, backups, security, and hardware maintenance.

When Are Remote Hands Services Useful?

Remote hands services are useful when the data center requires physical intervention. For example, a technician can reboot equipment, check a connection, or replace a component at your request.

This assistance does not replace system administration. Software, configurations, and day-to-day server management remain your responsibility unless the provider offers a separate managed service.

What Should You Plan for in the Event of a Hardware Problem?

A failure may require replacing a drive, power supply, memory module, or another component. Know in advance whether the provider offers on-site assistance, the response time, and how the service is charged. If you do not have easy physical access to the data center, these conditions can become critical.

What Does the Data Center Provide, and What Still Remains Your Responsibility?

A Professional Environment for Your Servers

The main benefit of colocation is access to an environment that is difficult and expensive to build and maintain in a small office. The data center provides reliable power, controlled cooling, network connectivity, and physical security without requiring the company to invest in its own server room.

Control Over the Hardware

The company still chooses its own servers and configurations. This is especially useful when you have specific requirements for storage, GPU resources, network architecture, or other specialized hardware.

Delta.BG’s colocation service is provided at the Equinix data center in Sofia, where equipment is housed in a professionally built and secure infrastructure environment featuring physical access control, redundant power supply, and cooling systems.

What Does Not Come Automatically With This Service?

A better physical environment does not automatically make the entire IT system redundant. A single server can remain a single point of failure. Backups, failover mechanisms, application redundancy, and recovery plans remain the business's responsibility unless included in a separate managed service.

Is the Workload Suitable for Your Own Hardware?

Colocation suits stable, predictable workloads that use server resources consistently. In that case, you can plan hardware capacity and use it efficiently over several years.

With highly variable workloads, physical infrastructure is more difficult to size. The company may pay for capacity used only during peak periods, while adding more resources requires purchasing and installing additional equipment.

Applications with specific requirements for GPUs, storage, network configuration, or other specialized hardware are a separate consideration. In these cases, physical control over the equipment may provide more value than the ability to scale resources quickly.

How to Decide Whether Colocation Is the Right Choice

It Is More Suitable When:

• You already have good hardware: The servers have enough useful life remaining, and you don't need to invest in new equipment.
• The workload is stable: Resources are used consistently and can be planned for several years.
• You have specific hardware requirements: GPUs, specialized storage, or custom network configurations make physical control more important.
• The office is no longer a suitable place for the servers: Power, cooling, security, or space are becoming constraints.
• You have the required technical support: You have an internal team or external partner that can administer and maintain the equipment.

Another Model May Be More Suitable When:

• You need to build everything from scratch: The cost of purchasing hardware and the upfront investment may make other hosting models more economical.
• The workload changes significantly: Resource requirements are difficult to predict, and a large share of physical capacity may remain unused.
• You need to scale resources very quickly: Physical hardware cannot be added as quickly as virtual resources.
• You do not want to manage your own hardware: If physical control does not provide a real benefit, owning the servers adds unnecessary maintenance and responsibility.

Conclusion

Before choosing colocation, briefly assess what your infrastructure is likely to look like over the next several years. Consider how long you plan to keep using the current hardware, how often you may need physical access, how you will respond to a failure, and which services the data center provider can take over. This way, the decision will be based not only on the monthly price, but on whether the model is practical and sustainable for day-to-day business operations.
