Environment Parity

What problem does it solve?

Environment parity means using the same infrastructure code across all environments, with only configuration values changing. This reduces "works on my machine" problems and ensures production behavior is tested before deployment.

Core Features & Use Cases

• Single Codebase: maintain one set of IaC across dev, staging, and prod with environment-specific values injected via configuration.
• Configuration-first approach: leverage Terraform tfvars or AWS CDK context to apply environment differences without changing the code.
• Best practices: ensure resource structure and security configurations remain consistent while varying only settings; provide guidelines for testing parity.
• Use Case: deploy the same Terraform/CDK code to dev and prod by toggling instance sizes, counts, and retention values through configuration files or contexts.

Quick Start

Clone the repository and apply environment-specific configurations to deploy consistently across environments.
