Imperative approach

Intuitive, step-by-step way.

Example:

CLI along with a bash script like: 

cli create vm
cli configure vm
...
cli create vpc
cli configure vpc
...
cli create db
cli configure db
...

Disadvantages:

  • When you need to scale it up or down you need to write custom scripts.
  • Doesn't scale well.
  • If you run multiple times, it will create each time.
  • You have to add error handling when one of the steps fails halfway.
