What is colocation and when does it pay off?
What colocation actually means
Colocation (often shortened to "colo") is renting space for your own server hardware inside a professional data centre. You buy and own the machines; the provider supplies the building, power, cooling, network connectivity, physical security and 24/7 monitoring. In other words, you keep full control of the hardware while outsourcing the expensive, difficult parts of running a server room.
This model sits between two others. With a VPS or a dedicated server you rent someone else's hardware. With colocation you bring your own, so you choose the exact CPU, GPU, RAM, disks and RAID layout, and the investment stays on your own balance sheet.
What you rent, and what you get
Colocation is usually sold by physical space and power. A typical agreement covers:
- Rack space: measured in rack units (1U is about 4.45 cm of height); a fraction of a rack, a full rack, or a private cage.
- Power: a committed draw in amps or kilowatts, usually with redundant A and B feeds.
- Bandwidth: a port speed with either a transfer allowance or an unmetered commit, plus your IP addresses.
- Remote hands: data centre staff who reboot, reseat cables or swap drives when you cannot be on site.
- Cross-connects: direct cabling to other networks, carriers or your own equipment in the same building.
A quick capacity check before you sign
Before you request a quote, write down what you actually need:
Server height: 2U Power draw: ~350 W typical / 500 W peak Redundant feeds: A + B (dual PSU) Uplink: 1 Gbps port Public IPs: /29 (5 usable) Access: remote hands + scheduled on-site visits
Underestimating power draw or forgetting redundant feeds is the most common planning mistake, and it is the hardest to fix once the rack is populated.
When colocation pays off
The economics favour colocation in a few clear situations:
- You already own suitable hardware: colocation lets you keep using it instead of paying to rent equivalent capacity.
- You need specific or unusual hardware: GPUs, large disk arrays or specialised network cards that rented plans rarely offer.
- Predictable, steady load: at scale and over several years, owning hardware can cost less than renting it.
- Compliance and data sovereignty: you know exactly which machine holds your data and in which jurisdiction, which helps with NIS2 and GDPR.
- Full control: firmware, kernel and hypervisor are all yours, with no shared-tenancy limits.
When it does not
Colocation is the wrong tool when flexibility matters more than ownership:
- Small or spiky workloads: a VPS scales up and down far more cheaply.
- No hardware and no wish to buy: a dedicated server gives similar control with none of the capital outlay.
- You need to grow or shrink in minutes: virtualised cloud resources are more flexible than physical boxes.
Where CloudHosting fits
We host colocated hardware in our own Riga data centre, with further capacity in the Netherlands and Dubai. That gives you EU data sovereignty when you want it, a non-EU option when you do not, redundant power and cooling, 24/7 human support and remote hands, and a network built for low-latency Baltic and European traffic. You keep the servers; we keep them powered, connected and physically secure.
Practical takeaway
Colocation pays off when you already own, or have a solid reason to buy, hardware you want to control for years, and you value EU data sovereignty and physical security over instant elasticity. If your needs are small, changing or short-term, a VPS or a dedicated server is usually the better first step. Map your power, space and bandwidth honestly before you sign, and colocation turns into a predictable long-term cost instead of a surprise.
