CDKでも「Expressモード」がサポートされたので、デプロイ時間を計測してみた

aws-cdk v2.1129.0で`cdk deploy --express`が追加されました。前回CloudFormation APIで検証したExpressモードと同じ構成をCDKで再現し、デプロイ所要時間が183秒から40秒（4.6倍）に短縮されることを確認しました

はじめに

前回、CloudFormationのExpressモードをAWS CLIで検証しました。

前回の結論は「通常182秒 → Express 61秒（3.0倍）」でしたが、CDK CLI未対応のためCloudFormation APIでの検証のみでした。

2026年7月1日（JST 22時）、aws-cdk v2.1129.0がリリースされ、cdk deploy --expressが追加されました。

今回は前回と同じ構成をCDKで再現し、Expressモードのデプロイ時間を確認します。

検証

検証環境

リージョン： ap-northeast-1
CDK CLI: v2.1129.0
aws-cdk-lib: 2.258.0
Node.js: 22（Dockerコンテナ上で実行）
VPC: デフォルトVPC
インスタンスタイプ： t3.micro
AMI: Amazon Linux 2023 (x86_64)

CDK スタック定義

前回記事と同じ5リソース構成をL2コンストラクトで再現しています。

import * as cdk from 'aws-cdk-lib';
import * as ec2 from 'aws-cdk-lib/aws-ec2';
import * as iam from 'aws-cdk-lib/aws-iam';
import { Construct } from 'constructs';

export class BenchStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const role = new iam.Role(this, 'BenchRole', {
      assumedBy: new iam.ServicePrincipal('ec2.amazonaws.com'),
    });

    role.addToPolicy(
      new iam.PolicyStatement({
        actions: ['s3:GetObject'],
        resources: ['*'],
      }),
    );

    const vpc = ec2.Vpc.fromLookup(this, 'DefaultVpc', { isDefault: true });

    const sg = new ec2.SecurityGroup(this, 'BenchSecurityGroup', {
      vpc,
      description: 'Benchmark security group',
    });

    new ec2.Instance(this, 'BenchInstance', {
      vpc,
      instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.MICRO),
      machineImage: ec2.MachineImage.latestAmazonLinux2023(),
      role,
      securityGroup: sg,
    });
  }
}

ec2.InstanceのL2コンストラクトが内部でInstanceProfileを生成するため、比較対象となる実体リソースは5つです（Role / Policy / InstanceProfile / SecurityGroup / EC2 Instance）。

Deployment time: 173秒でした。InstanceProfileのResource creation InitiatedからCREATE_COMPLETEまで2分11秒かかっています。前回のCloudFormation API検証（182秒、InstanceProfile待ち2分11秒）と同じ傾向です。

Express モードでのデプロイ

--expressフラグを追加するだけです。通常モードのスタックを削除後、同じ構成でExpressモードを試しました。

✨  Total time: 38.74s

Deployment time: 31秒でした。InstanceProfileはResource creation Initiatedから1秒で、CloudFormationイベント上はCREATE_COMPLETEになっています。

デプロイ完了後、CDK CLIが安定化継続中のリソースを一覧で表示します。

⚠️  Stack deployed using Express Mode. Resources still stabilizing: BenchSecurityGroup73EC7292, BenchInstanceInstanceProfile75E1DCDF, ...

デプロイ時間の比較

手法	CLI実行〜完了	倍率
CDK 通常モード	183秒	1.0x
CDK Express モード	40秒	4.6x
（参考）CFn API 通常モード（前回記事）	182秒	1.0x
（参考）CFn API Express モード（前回記事）	61秒	3.0x

「CLI実行〜完了」はcdk deployコマンドの実行開始から制御が戻るまでの所要時間（wall clock）です。CDKの場合はsynth + changeset作成 + CloudFormation処理を含みます。前回のCFn API計測（create-stack実行〜wait stack-create-complete完了）とはCDK側にsynthやchangeset作成が含まれる分の差はありますが、いずれもwall clockベースであり、傾向を比較する目安になります。

CDK CLIが出力するDeployment timeで見ると、通常173秒 → Express 31秒（5.6倍）でした。synthやChange Set作成を含むCLI全体時間では4.6倍、Deployment timeでは5.6倍です。

通常モード同士はほぼ同等（CDK 183秒 / CFn API 182秒）で、いずれもInstanceProfileの安定化待ちがボトルネックです。Expressモードの差（CDK 40秒 / CFn API 61秒）は、前回のwaitコマンドのポーリング間隔も一因と考えられます。

スタックイベントの比較

InstanceProfileの完了時間にフォーカスして比較します。

通常モード: InstanceProfileの完了待ちに2分11秒

3:55:56 PM | CREATE_IN_PROGRESS | AWS::IAM::InstanceProfile | Resource creation Initiated
3:58:07 PM | CREATE_COMPLETE    | AWS::IAM::InstanceProfile

Express モード: InstanceProfileのCREATE_COMPLETEが1秒後に記録

4:00:29 PM | CREATE_IN_PROGRESS | AWS::IAM::InstanceProfile | Resource creation Initiated
4:00:30 PM | CREATE_COMPLETE    | AWS::IAM::InstanceProfile | Resource operation completed using Express Mode. It may continue becoming available in the background.

Expressモードでは安定化確認の完了を待たずにデプロイが進むため、InstanceProfileの2分以上の待ち時間がなくなります。

destroyの場合、この構成ではEC2インスタンスのterminate処理が約1分を占めました。terminate後の依存リソースは数秒のうちにDELETE_COMPLETEとして記録されています。全体のDestroy timeは約73秒（4:01:20→4:02:33）で、deployほどの劇的な短縮は得られませんが、EC2 terminate後の後続削除が即座に進む効果は確認できました。

まとめ

aws-cdk v2.1129.0でcdk deploy --expressが使えるようになりました。前回と同じ構成で試したところ、デプロイ所要時間が183秒から40秒に短縮されました（4.6倍）。--expressフラグを付けるだけでスタック定義の変更は不要です。

なお、デプロイ速度をさらに追求する選択肢として、CloudFormationを経由せずSDKで直接デプロイするcdkdもあります。cdkdは対応リソースが限定される実験的なアプローチのため、CloudFormation/CDKの枠組みのまま短縮したい場合はcdk deploy --expressが手軽な選択肢になりそうです。

CDKでも「Expressモード」がサポートされたので、デプロイ時間を計測してみた
