Report: Infrastructure

Return to Agenda

This reports provides an overview of our Internet infrastructure. Most of infrastructure is composed of servers which are located in colocation facilities. A colocation facility is a space specifically designed to house computers. Typical colocation facilities have redundant power supplies, extensive cooling systems, and a series of cabinets where the servers are installed. We also use nonprofessional colocation facilities - meaning that they are setup in our offices and private locations.

A cabinet is like a stand-alone wardrobe. Server computers are typically shaped like pizza boxes, which slide into the cabinet to maximize the use of the space.

A single physical server (pizza box) sometimes can have multiple virtual servers on it. A virtual server is a server that acts and operates like a single physical server, but in fact shares its host server with other virtual servers. Virtual servers allow us to provision a complete system to a member without having to purchase a new physical server for each member.

Some servers we manage ourselves (meaning we run software updates and installations). These are managed servers. Other servers are managed directly by our members.
