プロジェクトの歴史

AWS introduced the AWS Cloud Development Kit in developer preview in 2018. The early pitch was infrastructure as code in familiar languages rather than hand-written JSON or YAML templates, with constructs compiling down to CloudFormation.

AWS announced general availability for the CDK's TypeScript and Python support on July 11, 2019. The project then expanded its language and construct ecosystem while keeping CloudFormation as the deployment engine.

AWS CDK v2 became generally available on December 2, 2021 alongside Construct Hub. Version 2 consolidated the AWS Construct Library into aws-cdk-lib, reducing the package sprawl that CDK v1 users had to manage.

採用の歴史

CDK was adopted by developers and platform teams who wanted the repeatability of infrastructure as code without giving up loops, functions, types, IDE tooling, and package reuse. AWS documentation describes support for TypeScript, JavaScript, Python, Java, C#/.NET, and Go.

Its package culture grew around constructs: reusable modules that describe cloud resources and higher-level patterns. That ecosystem matters because the cdk CLI is only one piece; real adoption depends on libraries, generated CloudFormation resource definitions, and repeatable synthesis/deploy workflows.

使われ方

Typical usage begins with cdk init, then cdk synth to generate a cloud assembly, cdk diff to compare deployed infrastructure, and cdk deploy to apply changes through CloudFormation. The CLI discovers the app command from cdk.json in the project directory, then falls back to ~/.cdk.json or command-line --app.

Configuration is split across CDK files and AWS shared files. CDK uses cdk.json, ~/.cdk.json, and cdk.context.json for app commands, context, feature flags, and cached lookups; AWS SDK/tooling uses ~/.aws/config and ~/.aws/credentials on Unix-like systems and %USERPROFILE%\.aws\config and %USERPROFILE%\.aws\credentials on Windows.

パッケージ好きにとっての重要性

For package nerds, aws-cdk is a Node-distributed cloud compiler dressed as a system CLI. The installed cdk binary coordinates local language runtimes, npm packages, generated constructs, AWS credentials, and CloudFormation APIs, so version skew can matter.

It is also significant because it normalized packaging infrastructure abstractions as libraries. CDK apps are dependency graphs as much as source trees, and the CLI's job is to turn that graph into deterministic cloud assemblies.
