Colocation hosting is a type of hosting service where a business or individual rents space for their own server in a data center. The customer is responsible for providing and maintaining their own server, but the data center provides security, power, cooling, and network connectivity for the server. Colocation hosting is often used by businesses that need to have a high level of control over their server and its environment, or that have data storage and bandwidth requirements that exceed the capabilities of traditional web hosting.
