Designer and CloudFormer are two very useful tools when you are in the process of architecting your infrastructure and are trying to add source control to your design.

That said, whenever you wear your DevOps hat, it's a different story. Using those tools markedly reduces the added value that CloudFormation provides by using the JSON format. If you got a chance to read some of the templates available or tried to use CloudFormer on your existing infrastructure, you probably noticed that raw CloudFormation templates tend to be fairly long and not don't repeat yourself (DRY).

From a DevOps perspective, one of the most powerful aspects of CloudFormation is the ability to write code to generate those templates dynamically. To illustrate that point, we are going to turn to Python and a library called troposphere to generate our Hello World CloudFormation template.
