This repository provides practical examples of AWS CloudFormation custom resources that enable developers to extend CloudFormation's native capabilities. These examples demonstrate how to integrate with AWS services and external systems during stack creation, updates, or deletion.

Key Features

• Resource Management — Examples for creating, updating, and deleting custom resources within CloudFormation stacks
• AWS Service Integration — Patterns for interacting with various AWS services beyond CloudFormation's built-in resources
• External System Coordination — Templates for coordinating with systems outside AWS during infrastructure deployment
• Lambda-backed Resources — Implementation examples using AWS Lambda functions as custom resource handlers
• Error Handling — Demonstrations of proper error reporting and rollback mechanisms for failed operations

Philosophy

These examples follow AWS best practices for CloudFormation custom resources, emphasizing reliability, security, and maintainability in infrastructure-as-code workflows.
