What is server colocation and why would you (or should you) do it?

Microsoft explains the process of colocation as:

Installing and maintaining a computer at an Internet Service Provider (ISP) that belongs to another company or group. For example, a company might colocate one of their servers at an ISP to save costs, or to make large-scale upgrades easier.

But there’s more to it than just that.

When you colocate a server, it is no longer on your company premises. Colocating at an ISP allows better access to a more robust and redundant Internet connection than you might have on your premises.

With a typical colocation arrangement, you own the server and are responsible for its management. The colocation firm is responsible for the Internet connection and environmental concerns. Colocation facilities provide a controlled environment with regard to factors such as temperature and humidity. The facility’s overall security measures and backup power supply are important measures for consideration, as well.
