Module 2 · Servers and computeLesson 4 of 4

Goal: Confirm you can tell a CPU shortage from a memory one and choose between a virtual machine and a container.

Four questions: three on this module, one on Module 1. Every answer explains itself, right or wrong.

What turns an ordinary computer into a server?
Your service slows down as traffic grows, but never crashes. Its memory is steady and CPU is at 100%. What does it need?
Your app needs a custom operating system kernel. What do you run it on?
From Module 1: you run your app on a PaaS. Who installs operating system security fixes?

Retry as often as you like.

Before you go, name each part.

Compute at a glance: from memory

Name each part before you reveal it.

Waits for requests and answers them.
Runs your code. Too little: slow.
Working space. Too little: stopped.
A machine's slice, with its own OS.
An app and its needs, sharing a kernel.
The five ideas in this module.
