The practice of placing things together in the same location, particularly in data centers where multiple companies house their servers. Also refers to the linguistic phenomenon of words frequently appearing together.
From Latin 'co' (together) and 'location' (place), formed in modern English in the 20th century. The computing sense emerged in the 1990s with the growth of internet infrastructure and shared data facilities.
Colocation revolutionized the internet by allowing small companies to share expensive infrastructure - it's like having a high-tech apartment building where everyone shares utilities, security, and maintenance, but keeps their own private space.
