DEPLOYMENT_HEROKU_RAILS.md

Deploying a Rails app to Heroku

Learning Objectives

  • Why do we need to deploy our code?
  • Explain the difference between PaaS and IaaS
  • Deploy an app to Heroku
  • Run a Heroku app locally
  • Set up a remote database
  • Configure a remote server

Why do we need to deploy?

  • Some people are still getting confused as to why databases local to their machine can't be accessed by others, why we seed data, etc
  • Difference b/w Heroku and Bit Ballooon

What is Heroku and why are we using it?

Discuss PaaS - Platform as a Service as compared to IaaS like Amazon EC2, etc

IaaS gives you components you need in order to build things on top of it; PaaS gives you an environment where you just push code and some basic configuration and get a running application. IaaS can give you more power and flexibility, at the cost of having to build and maintain more yourself.
