Colocation centre

[1] Typically, the customer owns the information technology (IT) equipment and the facility provides power and cooling.

Customers retain control over the design and usage of their equipment, but daily management of the data centre and facility are overseen by the multi-tenant colocation provider.

[2] Buildings with data centres inside them are often easy to recognize by the amount of cooling equipment located outside or on the roof.
