Which Part of the Server?

About this interactive

The lesson's stack, from the bottom: - **Hardware:** a physical server, such as the rack-mount Dell, with two CPUs, room for over a terabyte of RAM, and redundant fans and hard drives. - **Hypervisor:** ESXi installed on the hardware lets one box run many virtual machines. - **Operating system:** Ubuntu, Debian, Windows Server, in those virtual machines (or straight on the hardware). - **Service:** the software that serves clients, such as Apache delivering web pages. This is the true heart of a server: install Apache on a laptop and the laptop is serving.

What you'll learn

Sort what makes up a server into its parts: the service software that serves clients, the operating system, the hypervisor that hosts virtual servers, and the hardware
Recognise that the service is what truly makes a server, since any computer running one serves clients
