Infrastructure as Code

Core practices of IaC

Everything defined as code
- Reusability
- Consistency
- Transparency
Validation and testing (just as important as testing code)
Small and simple parts that you can change independently
- You want your code to be as simple as possible

Configuration management vs infrastructure provisioning

Configuration management: Terraform
Infrastructure provisioning: Chef, Puppet, Ansible
With the growth of microservices and serverless

Where do I start?

Automate one thing at a time and start slow
DevOps culture is about making small changes, one at a time, and improve upon them
Don't try to do all at once
Automate the most tedious processes first, like server builds
If you try to do everything at once, you'll most likely have to go back and redo it
