1. Recipes and Presses
@JohnContad / @REATechBlog

2. Launch Configurations
- A ‘blueprint’ on how to make a server
- Contains instructions on how to make a server
- ‘How do I build this thing?’

3. Autoscaling Groups
- Sets how many instances to make
- Set manually, or automatically
- Ties to Launch Configuration
- ‘How many do I build’?

4. Why?
- Setting up instances manually is tiresome
- Humans make human errors
- Predictability and repeatability

● Create and Attach an Autoscaling Group
● Have your Autoscaling group automatically attach things
to your ELB
