CloudFormation

Question 1

Can you modify a cloud formation template?

Answer 1

No, the idea is that you create versions of the templates instead of deletion.

Question 2

When you delete a cloud formation template, what happens to resources created by the template in the stack?

Answer 2

All resources provisioned by the template will be deleted.

Question 3

Aside from provisioning Infrastructure, what else can a cloud formation template be used for?

Answer 3

We can use CF templates for cost estimation

Question 4

You have modified a cloud formation template and are going to apply these changes as a direct update. When are the changes deployed and to what stack resources? How does this differ from a change set?

Answer 4

Direct updates are deployed immediately to changed resources only. In a change set - cloudfront will identify and list any resource which will be added, deleted or modified. You can then choose to apply changes immediately, delete the change set or do nothing.
