Simply put, self-hosted systems are those systems that you have on your premises. They are the servers powering up your firm that sit right in your office space (usually a closet) and the PCs to which they are connected. With a self-hosted system, everything is within sight and under your immediate control. Smaller firms might not have a server, but rather a network of a few computers, though not as complex as a server setup, these computer-to-computer networks are still self-hosted systems.
