Question 1

What's the difference between Infrastructure Automation and Infrastructure as Code (IaC)?

Accepted Answer

Infrastructure as Code is the approach of describing infrastructure in code (templates/config files). Infrastructure Automation is the broader practice of using tools and workflows to provision, configure, update, and manage that infrastructure automatically—often using IaC plus CI/CD pipelines, policy checks, and automated testing.

Question 2

When should I use Infrastructure Automation?

Accepted Answer

Use it when you need repeatable environments (dev/test/prod), frequent infrastructure changes, multiple regions/accounts, or strong compliance/audit needs. It’s especially useful when manual console work is slow, error-prone, or hard to reproduce. For very small, one-off experiments, manual setup can be fine, but automation pays off quickly once you need consistency or scale.

Question 3

How much does Infrastructure Automation cost?

Accepted Answer

Many IaC tools are free or included (for example, Terraform CLI is free; AWS CloudFormation and Azure ARM template deployments don’t have separate per-template fees). Costs usually come from the infrastructure you create (compute, storage, networking), plus any paid tooling (e.g., Terraform Enterprise/Cloud paid tiers, CI/CD runners, secrets management, policy tools) and engineering time to build and maintain modules, pipelines, and tests.
