What is this?
Infrastructure automation treats servers, networks, and policies as code reviewed in Git and applied by pipelines.
Why should you care?
AwsVerse recreates DR region from Terraform modules in hours instead of weeks of manual setup.
See it live — copy this example
Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).
aws cloudformation create-change-set \
--stack-name awsverse-network \
--change-set-name add-nat-az-b \
--template-body file://network.yaml \
--change-set-type UPDATEWhat happened?
- Creates a change set previewing stack updates before execution.
- Review diff, then execute-change-set if safe.
Practice next
- Store IaC in Git with PR reviews.
- Run terraform plan or CFN change set in CI.
- Apply only from pipeline after approval.
- Enable CloudFormation drift detection.
- Add OPA policy check on Terraform plan output.
Remember
IaC = reproducible infra. Review plans in CI. No manual prod changes.
AwsVerse DR drill
Simulate region loss annually.
Outcome: Terraform apply in secondary region restores network stack in 45 minutes.
