Deployments & Managing Infrastructure at Scale Flashcards

1
Q

What is CloudFormation?

A

A declarative way of outlining your AWS Infrastructure, for any resources (most of them are supported).
Then CloudFormation creates those for you in the right order with the exact configuration that you specify

Q

What are the benefits of AWS CloudFormation?

A
  1. No resources are manually created, which is excellent for control
  2. Changes to infrastructure are reviewed through code
  3. Each resource within the stack is tagged with an identifier so you can easily see how much a stack cost you
  4. You can estimate the costs of your resources using the CloudFormation template
  5. Savings strategy: In Dev, you could automation deletion of templates at 5PM and recreate at 8AM, safely
  6. Ability to destroy and re-create an infrastructure on the cloud on the fly
  7. Automated generation of Diagram for your templates
  8. Declarative programming (no need to figure out ordering and orchestration)
  9. Leverage existing templates on the web
  10. Leverage the documentation
  11. You can use ‘custom resources’ for resources that are not supported
