Mastering AWS CDK: A Comprehensive Guide (Overview)

Mastering AWS CDK: A Comprehensive Guide

Welcome to this comprehensive series on the AWS Cloud Development Kit (CDK)! Whether you're new to infrastructure as code or looking to enhance your cloud deployment strategies, this series will guide you through everything you need to know about AWS CDK.

What is This Series About?

This five-part series explores AWS CDK from the ground up, covering fundamentals, practical implementation, best practices, testing strategies, and advanced security techniques. Each article builds on the previous one, providing a complete learning path from beginner to advanced user.

As shown in the visual guide above, AWS CDK encompasses several key areas:

What is AWS CDK?

• A framework for defining cloud resources using programming languages
• Supports TypeScript, JavaScript, Python, Java, C#, Go and other languages
• Extensive learning resources including AWS Black Belt seminars and workshops

Key Benefits

• Type safety: Detects errors at compile time
• Code reuse: Standardizes best practices and improves quality
• Improved productivity: IDE completion, conditions, loops, etc.
• Infrastructure and app integration: Unified repository management
• Scaling and governance: Easy deployment across multiple environments/regions

CDK Components

• App: Top-level construct that defines stack dependencies
• Stack: Corresponds to one CloudFormation stack
• Construct: Creates resource definitions in the stack
• Construct levels:
  • L1: 1:1 mapping with CloudFormation resources (Cfn prefix)
  • L2: Higher level of abstraction (reduces boilerplate)
  • L3: Patterns combining multiple resources

CDK Commands

• cdk init: Set up necessary files
• cdk bootstrap: Create resources needed for CDK
• cdk deploy: Deploy resources to AWS environment
• cdk diff: Check differences between code and deployed environment
• cdk synth: Generate CloudFormation template
• cdk destroy: Delete stacks
• cdk list / cdk ls: Display list of stacks in the app

Development Methods

• Required knowledge: AWS resources basics, CloudFormation experience, programming experience
• Required environment: AWS CLI v2, Node.js, text editor (IDE recommended)
• Directory structure: Separate into stacks, resources, utils, parameters
• Stack division: Manage with a single stack when possible (cross-stack references are complex)
• Construct ID naming conventions: PascalCase, simple names
