On a scale from 🌈 to 💩
how do you feel about CloudFormation?

third option: ⛏️

CloudFormation

Infrastructure as Code (template) 🛣️

YAML / JSON ✍️

Deploy and connect resources 🏗️

Organized as stacks 📚

Continuous integration/development ♻️

IAM roles & policies 👮‍♀️

Check errors / Automatic rollback 💥

No additional cost  👍

What CF does not do

Coffee ☕

Access your machine locally (SAM) 🖥️

Check that your stack works the way you expect it to work (tests) 🔧

Monitor cost of deployed resources 💰

CloudFormation is not a super admin 🗿

AWS CloudFormation: A stack in the sky

Link to the talk event on Meetup: https://www.meetup.com/Portland-Serverless-Architecture-Meetup/events/268360327/. Tired of zipping your Lambdas by hand every time you want to deploy to production? What if I told you that there is a solution that lets you deploy your entire application to AWS from your local machine? What, you don't believe me? But this tool even has a cool aerial name that's like super on point because it's about cloud computing. Too good to be true? Great news! It's called CloudFormation.
