Colocation Datacenters allow you to rent space for your servers to run. You can rent from 1U of space to a dozen 42U racks for your equipment. Colocation facilities allow you to run your equipment in a certified datacenter environment even if your employees work in your basement.

Considerations

Space – You can rent from a single U to a Full Rack for your equipment
Power – Datacenter provide a number of Amps of total power. This can be as low as 1. Make sure your equipments power draw matches with what you are purchasing.
Networking – You will have options for Speed, Total Bandwidth Usage, number of IP Addresses, and use of specific Routing Protocols.
Security – If you rent a single U in a rack then other tenets will have physical access to your equipment. Renting a Half Rack or Full Rack generally gives you the ability to physically lock your rack. For more security many datacenters will build cages to contain all of your equipment.
Tech Support – Some datacenters provide basic support services such as power cycling equipment, or hooking up an IP KVM to your servers if they fail to boot into an OS.
