Infrastructure as Code Mentality

Why prefer Infrastructure as Code (Terraform/CloudFormation/Bicep) over click-ops in cloud consoles for production?

Answers use simple, clear English.

Quick interview answer

IaC makes changes reviewable, repeatable, and recoverable. Drift is detectable; environments can be cloned. Click-ops does not scale across teams and creates snowflake accounts.

Detailed answer

IaC makes changes reviewable, repeatable, and recoverable. Drift is detectable; environments can be cloned. Click-ops does not scale across teams and creates snowflake accounts. Pair IaC with policy-as-code and least-privilege CI roles.

Real example & use case

PR adds an S3 bucket with encryption required; Atlantis/Terraform plan runs in CI before apply.

Pros & cons

Pros: auditability. Cons: learning curve; state file locking/security must be handled.
