AWS CloudFormation: A stack in the sky

By Yves Gurcan

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.
