How do you manage different environments (dev, prod) in Lambda?

Managing different environments like development, staging, and production in AWS Lambda ensures safe deployment and isolation of configurations. AWS offers multiple ways to separate and manage environment-specific settings using function versions, aliases, environment variables, and Infrastructure as Code tools.

Common Strategies for Environment Management

Use Lambda aliases like dev, staging, and prod pointing to specific function versions.
Set environment-specific configuration using Lambda environment variables.
Deploy separate Lambda functions for each environment with unique names (e.g., my-function-dev, my-function-prod).
Use infrastructure tools like CloudFormation, SAM, or Terraform with parameterized templates.
Manage IAM roles and policies to restrict access based on environment.
Use separate AWS accounts or isolated VPCs for production-critical functions.
