I LOOOOOVE Heroku. It makes deploying so easy and convenient. Better yet, it has free tier you can use to test things out before start paying money for more dynos. It's not the fastest, but when you have a small team without devops or just getting the product-market fit, it's perfect. It allows you to focus on development features. No need to spend money up-front for premature optimization. Just get the product out there and test. Once you find product-market, you can decide whether to stay with Heroku or move on to EC2.
