Environments

Why environments matter

Environments keep changes isolated so you can test safely without disrupting production. Each environment has its own services, variables, and deployments.

Common environment setup

• Dev for local testing and rapid iteration.
• Staging for QA and release validation.
• Production for live traffic.

Environment tips

• Use different databases per environment to avoid data leaks.
• Keep secrets scoped to a single environment.
• Mirror configuration between staging and production for reliable tests.
