Colocation Hosting
Colocation hosting is an arrangement where a customer owns their physical server hardware but rents rack space, power, cooling, and network connectivity for it inside a third-party data center facility.

Colocation hosting is an arrangement where a customer owns their physical server hardware but rents rack space, power, cooling, and network connectivity for it inside a third-party data center facility.
Overview
Colocation (often shortened to 'colo') differs from every other hosting model in one key way: the customer, not the provider, owns the physical server. Instead of renting compute from a provider as with Dedicated Server Hosting or VPS Hosting, a colocation customer purchases and configures their own hardware, then ships it to a data center facility that provides the rack space, redundant power, cooling, physical security, and internet connectivity needed to keep it running. This model appeals to organizations that want full control over their hardware — specific components, custom configurations, or hardware they already own — without the capital expense and complexity of building and operating their own data center. Facility operators typically offer service-level agreements around uptime, power redundancy, and network availability, and many support cross-connects into cloud providers' networks via services like Direct Connect / ExpressRoute. Because colocation still requires owning, maintaining, and eventually replacing physical hardware — plus arranging remote hands support for anything that needs physical intervention — it's generally chosen by organizations with existing hardware investments, specific compliance or performance requirements, or hybrid infrastructure strategies, rather than by smaller teams better served by cloud or dedicated hosting.
Key Concepts
- Customer owns the physical server hardware, not the facility
- Facility provides rack space, power, cooling, and connectivity
- Full control over hardware specification and configuration
- Typically backed by facility SLAs for uptime and power redundancy
- Supports cross-connects into cloud provider networks
- Requires arranging remote hands support for physical maintenance
