n. C / U
C1 Advanced US //ˈkoʊɫoʊ// co·lo

n. a secure building where companies keep their computer servers and networking equipment. You use this service when you want to rent space for your hardware instead of keeping it in your own office.

n. a data centre facility in which a business can rent space for servers and other computing hardware. Often used as a shortened form of 'colocation'.


SIMPLE

We moved our servers to a local colo to save on cooling costs.

CONTEXTUAL

The startup decided to use a colo facility rather than building their own server room to ensure 24/7 power backup.

COMPLEX

Migrating to a high-tier colo provides the enterprise with redundant power systems and carrier-neutral connectivity that would be prohibitively expensive to maintain on-premises.
