Multi environment

So, I would like to have a test environment separate from the production environment.

The above walkthrough deals with the requirement in the following way:

• 1 pipeline for everything.
• 2 stacks, and 2 consecutive pipeline stages in order to deal with that.
• Pauses and waits for approval prior to pushing to production. Deletes the test stack at that point.

I think this is the way to proceed.

Something else - how would I handle development off the master branch? Presumably by instantiating the stack separately. I.e. one pipeline instance per branch, and 2 envs per pipeline. I think this makes sense. I don't necessarily need to us the pipeline for the dev branch either - i could just get CF to build it directly from the GUI, or use sam on the console.

Conditional resource creation based on env-type. Excellent! This will allow me to keep a single template for both envs / stages.
