Question 1

What's the difference between IaaS, PaaS, and SaaS?

Accepted Answer

IaaS gives you raw building blocks like VMs and storage that you manage yourself, PaaS manages the OS and runtime so you just deploy code, and SaaS is a complete ready-to-use application with no infrastructure to manage.

Question 2

What's the difference between horizontal and vertical scaling?

Accepted Answer

Vertical scaling increases the resources of a single machine, while horizontal scaling adds more machines and distributes load across them, which is generally preferred in the cloud for its lack of a hard ceiling.
