Module 1 · What the cloud isLesson 3 of 3

Goal: Confirm you can say what renting computers changes and place a hosting option on the IaaS, PaaS, SaaS ladder.

Four questions on this module. Every answer explains itself, right or wrong.

You want to run a web API and never think about operating system patches. Which model?
Your team uses a hosted accounting tool. A staff member who left still has a login. Whose job is it to remove it?
Most of your users are in one part of the world. What should you choose with that in mind?

Retry as often as you like.

Before you go, name each part.

The cloud at a glance: from memory

Name each part before you reveal it.

Computers in someone else's data center.
Billed while it runs; scale in minutes.
Pick where it runs, near your users.
Each model hands more work to the provider.
The four ideas in this module.
