Terraform Mastery (Senior → Principal)

Operate

• Start from ownership boundaries, blast radius, and change safety.
• Treat Terraform as infrastructure lifecycle management, not just file generation.
• Prefer module clarity, predictable plans, and explicit environment strategy.
• Optimize for safe review, repeatable rollout, and recovery from bad state or bad assumptions.

Default Standards

• Modules should encode reusable intent, not abstract every resource mindlessly.
• State strategy must reflect team boundaries and failure domains.
• Plans should be reviewable by humans.
• Provider/version policy should be deliberate.
• Drift, imports, and emergency changes need known workflows.
