VPC上にデプロイしたSIEM on Amazon ESで既存S3バケットのログを分析してみた

既にS3バケットに保存されているログもSIEM on Amazon ESで分析できますよ。
2021.07.12

既にS3バケットにログを収集しているんだけど、このままだとSIEM on Amazon ESで分析できない?

こんにちは、のんピ です。

前回、以下のブログを投稿しました。

内容は、SIEM on Amazon ESのスタックが作成したログ収集用S3バケットに、CloudTrailや、VPC Flow Logs、FSx for Windows File Serverのファイルアクセス監査ログを保存して、可視化するといったものです。

以下、AWS公式ドキュメントの図を見ると、ログ収集用S3バケットのデータ保存は3パターンがあることがわかります。

抜粋: SIEM on Amazon Elasticsearch Service - アーキテクチャ

  1. Kienesis Data Firehoseを使用して、ログ収集用S3バケットにログを転送する
  2. サービスのログの出力先を、ログ収集用S3バケットに指定する
  3. 既存のS3バケット内のオブジェクトから、ログ収集用S3バケットにレプリケーションする

それでは、既にログをS3バケットに集約している場合は、どの方法を選択すれば良いでしょうか。

1と、2のように、わざわざ全てのログの出力先を変更するのは手間なので、もう少し楽をしたいですよね。

今回は、3. 既存のS3バケット内のオブジェクトから、ログ収集用S3バケットにレプリケーションするをして、過去ログをSIEM on Amazon ESに読み込ませたいと思います。

また、実は既存のS3バケットをSIEM on Amazon ESのログ収集用S3バケットとして取り込むこともできます。

公式ドキュメントに以下のような記載があります。

すでにお持ちの S3 バケットを SIEM on Amazon ES の CloudFormation スタックに取り込み、AWS CDK で管理します。ログ取り込み用にS3 バケットポリシーを追加・修正します。S3 のバケットポリシーやその他のバケット設定は上書きされるのでご注意ください。SIEM on Amazon ES の初期インストール時にのみ設定可能です。 既存の S3 バケットから SIEM on Amazon ES にログを送信しつつ、S3 バケットポリシー等はご自身で引き続き管理する場合は、この手順はスキップしてください。

高度なデプロイ - 既存の S3 バケットの取り込み

S3 のバケットポリシーやその他のバケット設定は上書きされるのでご注意ください。」という文章がかなり要注意ですね。また、AWS CDKで管理する必要があるというのもポイントです。

今回は、以下のログを保存したS3バケットを作成して、そのS3バケット内にあるログをSIEM on Amazon ESに読み込ませたいと思います。

  • CloudTrail
  • Security Hub
  • Amazon Linux 2の /var/log/messages

いきなりまとめ

  • 既存S3バケットをインポートすることで、過去のログを取り込むことができるが、S3のバケットポリシーの変更や、AWS CDKによる管理が発生するなど制約があるため要注意
  • お試しでSIEM on Amazon ESを使ってみたいなら、Same-Region レプリケーションでSIEM on Amazon ESのログ収集S3バケットにレプリケーションする方が良いかも

検証環境

検証を行う環境は以下の通りです。

既存S3バケットのログをSIEM on Amazon ESに読み込ませる方法として、以下のパターンを検証します。

  1. Same-Region レプリケーション(SRR)を使用して、既存S3バケットのログSIEM on Amazon ESのログ収集S3バケットにレプリケーションする
  2. AWS DataSyncを使用して、既存S3バケットのログSIEM on Amazon ESのログ収集S3バケットにレプリケーションする
  3. 既存S3バケットをSIEM on Amazon ESにインポートする

ログを出力するリソースのデプロイ

AWS CDKの構成

デプロイ

まずはCloudTrailや、Security Hubなどのログを出力する環境をAWS CDKで作成していきます。

AWS CDKの実行環境のディレクトリの構成は以下の通りです。

8 directories, 17 files

メインで動かすのは./lib/log-resorce-stack.tsです。ここで全てのリソースを作成しています。

./lib/log-resorce-stack.tsの大まかな処理の流れは以下の通りです。

  • ログ収集用のS3バケットの作成
  • Security Hubの検知内容に、レコード毎に改行を追加するLambda関数の宣言
  • Amazon Linux 2の /var/log/messagesのCloudWatch Logs用のロググループの作成
  • SSM用のIAMロールの作成
  • Kinesis Data Firehose用のIAMロールの作成
    • Security Hubの検知内容をS3バケットに配信する用
    • CloudWatch Logsに出力したAmazon Linux 2の /var/log/messagesをS3バケットに出力する用
  • Kinesis Data Firehose配信ストリームの作成
    • Security Hubの検知内容をS3バケットに配信する用
    • CloudWatch Logsに出力したAmazon Linux 2の /var/log/messagesをS3バケットに出力する用
  • CloudTrailの設定
  • GuardDuryの設定
  • IAM Access Analyzerの設定
  • Security Hubの設定
  • VPCの作成
  • Kibanaにアクセスする際に使用するポートフォワーディング用のEC2インスタンスにアタッチするセキュリティグループの作成
  • EC2インスタンスの作成
  • CloudWatch Agentの設定ファイルの読み込み

実際のコードは以下の通りです。

また、AWS CDK で3つ以上の AZ に Subnet を作成する際には、以下ブログの通り、AWSアカウントIDとリージョン名を指定する必要があります。

そのため、以下のように環境変数を使って、AWSアカウントIDとリージョン名を指定する指定してあげます。

./bin/log-resource.ts

#!/usr/bin/env node
import "source-map-support/register";
import * as cdk from "@aws-cdk/core";
import { LogResorceStack } from "../lib/log-resorce-stack";

const app = new cdk.App();
new LogResorceStack(app, "LogResorceStack", {
  env: {
    account: process.env.CDK_DEFAULT_ACCOUNT,
    region: process.env.CDK_DEFAULT_REGION,
  },
});

続いて、今回作成したLambda関数について補足します。

JSONオブジェクトはKinesis Data Firehoseに送られると、1行に複数のJSONオブジェクトが保存されます。

Q8. Amazon Kinesis Firehose を利用してCloudWatch LogsをS3に転送してそれをAthena で分析したいのですが、Kinesis Firehoseを通すと{json}{json}のように1行に複数のJSONオブジェクトが保存されるようです。このデータを効率的にAthenaで分析するにはどういった方法がありますか?? A8. Amazon Kinesis FirehoseにはData TransformationをAWS Lambdaで行う機能がございますので,こちらを使って所望の形式に変換すると良いです.

AWS Black Belt Online Seminar「Amazon Athena」の資料およびQA公開

そのため、以下Lambda関数を使って、Security Hubの検知内容をJSONオブジェクト毎に改行を追加してあげます。

./src/lambda/functions/add-newline-to-json.ts

import { Context, Callback } from "aws-lambda";

interface Record {
  recordId: string;
  approximateArrivalTimestamp?: string;
  result?: string;
  data: string;
}

interface OutputRecords {
  records: Record[];
}

// Function to add a new line to json.
const addNewLineToJson = async (record: Record): Promise<Record> => {
  const payload: string = Buffer.from(record.data, "base64").toString("utf-8");

  console.log("Decoded payload:", payload);

  return new Promise((resolve, reject) => {
    resolve({
      recordId: record.recordId,
      result: "Ok",
      data: Buffer.from(payload + "\n", "utf8").toString("base64"),
    });
  });
};

// main
exports.handler = async (
  event: any,
  context: Context,
  callback: Callback
): Promise<OutputRecords> => {
  console.log(event);

  /* Process the list of records and transform them */
  const output: Record[] = await Promise.all(
    event.records.map(async (record: Record) => {
      return await addNewLineToJson(record);
    })
  );

  console.log(`Processing completed.`);
  console.log("output");
  console.log(output);

  return { records: output };
};

あとは、cdk deployを実行することで、各種リソースがデプロイされます。

CloudWatch Logsの設定

/var/log/messagesをCloudWatch Logsに出力したいので、EC2インスタンスにCloudWatchの設定を行います。
設定は以下ブログのCloudWatch Agentのインストール・設定と同じ手順で行いました。

実行すると、以下の通りCloudWatch Logsに/var/log/messagesに出力されています。

S3バケットに出力されたログの確認

各種ログがS3バケットに出力されているか確認します。

対象のS3バケットを確認すると以下のようになっており、正常にログが出力されているようでした。

試しにSecurity Hubのログを開いてみると、以下の様にJSONオブジェクト毎に改行されていました。

SIEM on Amazon ESをVPC上にデプロイ

AWS CDKの構成

デプロイ

途中までは、以下ブログと同じ手順になります。SIEM on Amazon ESのデプロイの章のデプロイ準備と、デプロイ 1. ソースコードのクローン - 4. AWS CDKのセットアップを参考にしながら進めます。

SIEM on Amazon ESをパブリックアクセス (Amazon VPC 内)にデプロイ

以下コマンドで、SIEM on Amazon ESをデプロイします。

# SIEM on Amazon ES をパブリックアクセス環境にデプロイする場合のcdk.jsonを作成
> cp -a cdk.json.vpc.sample cdk.json

# 既存のVPC、サブネットのIDをcdk.jsonに記載する
# 変更箇所
# - vpc_type: 既存のVPC上にデプロイするため"import"に変更
# - imported_vpc_id: デプロイ先のVPCのIDを入力
# - imported_vpc_subnets: デプロイ先のサブネットのIDを3つ以上入力
> vi cdk.json

# 変更前と変更後の差分情報の確認
> diff -u cdk.json.vpc.sample cdk.json                                                                                                                             日  7/ 4 20:57:44 2021

aes-siem: creating CloudFormation changeset...




 ✅  aes-siem

Outputs:
aes-siem.KibanaAdmin = aesadmin
aes-siem.KibanaPassword = koq5Jv%2
aes-siem.KibanaUrl = https://vpc-aes-siem-xxxxxxxxxxxx.us-east-1.es.amazonaws.com/_plugin/kibana/
aes-siem.RoleDeploy = arn:aws:iam::<AWSアカウントID>:role/aes-siem-deploy-role-for-lambda

Stack ARN:
arn:aws:cloudformation:us-east-1:<AWSアカウントID>:stack/aes-siem/b5f30900-dcbf-11eb-b078-0a392ab5a299

20〜30分ほどでデプロイは完了し、KibanaのURLやID、パスワードが発行されます。

デプロイが完了したら、Amazon ESのコンソールを確認してみます。以下のように、ドメインが作成されていることが確認できます。

Same-Region レプリケーション(SRR)のパターン

レプリケーションルールの作成

それでは、Same-Region レプリケーション(SRR)のパターンから試してみます。

既存のログ収集用S3バケットを選択し、管理タブからレプリケーションルールを作成をクリックします。

レプリケーションルール名や、ソースバケットのスコープ、送信先のバケット名を選択します。

レプリケーションに必要なIAMロールを指定し、暗号化の設定を行います。

既存のログ収集用S3バケットにログが出力されたら、なるべく早くレプリケーションして欲しいので、レプリケーション時間のコントロール(RTC)を有効にして、保存をクリックします。

レプリケーションルールが正常に作成されると、以下のような画面になります。

しばらく待つと、以下のようにログファイルが同期され始めます。

Same-Region レプリケーションの注意点としては、以下ブログに記載の通り、レプリケーション設定前に存在しているオブジェクトはレプリケーションされません

基本的に CRR と同じく以下のようなものがあげられます。

  • レプリケーション設定前に存在しているオブジェクトはレプリケーションされません
  • 既存オブジェクトは AWS CLI などを使ってコピーする必要があります
  • 双方のバケットでバージョニングの有効化が必要
  • バケット所有者が権限を持っていない場合はレプリケーションされません
  • GLACIER または DEEP_ARCHIVE ストレージクラスに格納されているオブジェクトはレプリケーションされません
  • 多段レプリケーションはできません
  • ライフサイクル構成によって実行されるアクションはレプリケーションされません
  • バケットレベルのサブリソースの更新はレプリケーションされません
  • たとえば、ライフサイクル設定を変更したり、通知設定をソースバケットに追加した場合、これらの変更は宛先バケットに適用されません

[アップデート] 同一リージョン内でS3バケットのレプリケーションが出来るようになりました!

そのため、既存のログファイルについては、AWS CLIなどで自分でレプリケーションする必要があります。

今回は、以下のように、aws s3 syncコマンドを使ってレプリケーションをしました。

aws s3 sync s3://logresorcestack-centralizedbucketa7c16f21-dhgqky8w3f6y/ s3://aes-siem-<AWSアカウントID>-log/

すると、以下のように、Security Hubや、CloudTrail-Digestもレプリケーションされていました。

ログをKibanaで確認する

ログファイルをSIEM on Amazon ESのS3バケットにレプリケーションしたので、Kibanaでログが正常に読み込めているか確認してみます。

まず、今回はVPC上にSIEM on Amazon ESをデプロイしたので、外部からでもアクセスできるようにポートフォワーディングをします。

ポートフォワーディングをする際は、以下コマンドで、Public SubnetにデプロイしたEC2インスタンスを使用します。

ssh -i "<キーペア名>.pem" ec2-user@ec2-18-209-166-9.compute-1.amazonaws.com -N -L 10443:vpc-aes-siem-xxxxxx.us-east-1.es.amazonaws.com:443

ポートフォワーディングをした状態で、https://localhost:10443/_plugin/kibana/にアクセスします。

保護されていない通信と表示されますが、Kibanaのログイン画面が表示されることが確認できました。続けて認証情報を入力してLog Inをクリックします。

Kibanaの初期設定は、以下ブログのログの可視化の章のKibanaの設定を参考にしながら進めます。

初期設定が完了したら、ドロワーメニューより、Discoverをクリックして、読み込んだログの一覧を出力します。

Security Hubのログの一覧も表示してみます。

Amazon Linux 2の /var/log/messagesのログの一覧も表示してみます。

いずれも正常にログを読み込めていそうですね。

レプリケーションルールの削除

次の検証に影響が出るので、作成したレプリケーションルールを削除します。

既存ログ収集用S3バケットの管理タブから、作成したレプリケーションルールを選択して、削除をクリックします。

確認のウィンドウが表示されるので、レプリケーションルールを削除をクリックします。

レプリケーションルールが削除されたことが確認できました。

AWS DataSyncのパターン

古いログファイルの削除

事前準備として、SIEM on Amazon ESのS3バケット上のログファイルを削除します。

AWSLogs/を選択して、削除をクリックします。

確認の画面が表示されるので、テキストフィールドに削除と入力し、オブジェクトの削除をクリックします。

全てのログファイルが削除されたことが確認できました。

インデックスの削除

続いて、Amazon ESが読み込んだログのインデックスを削除します。

KibanaのドロワーメニューからDev toolsをクリックして、ConsoleにDELETE /log-*を入力して、▶︎をクリックします。

再度、ドロワーメニューより、Discoverをクリックして、読み込んだログの一覧を出力します。

No results match your search criteriaと表示され、インデックスが正常に削除されたことが確認できます。

タスクの作成

それでは、DataSyncのタスクを作成します。

DataSyncのコンソールに移動して、左メニューのTaskから、Create taskをクリックします。

送信元のS3バケットの設定をします。情報を入力して、Nextをクリックします。

次に送信先のS3バケットの設定をします。情報を入力して、Nextをクリックします。

続いてタスクの設定をしていきます。ここでは、スケジュールやフィルタリングルールなどを設定します。情報を入力して、Nextをクリックします。

最後に設定の再確認です。設定に問題がなければ、Create taskをクリックします。

毎時0分に実行するようスケジュールしたので、23:00になってしばらくすると、タスクが実行されました。

タスクが完了すると、以下のようにステータスがSuccessになります。

SIEM on Amazon ESのS3バケットを確認すると、ログがレプリケーションされていることがわかります。

ログをKibanaで確認する

ポートフォワーディングをした状態で、https://localhost:10443/_plugin/kibana/にアクセスします。

Amazon Linux 2の /var/log/messagesのログの一覧も表示してみます。

いずれも正常にログを読み込めていそうですね。

確認ができたので、後片付けとして、DataSyncのタスクを削除します。

既存S3バケットをSIEM on Amazon ESにインポートするパターン

SIEM on Amazon ESの削除

改めて公式ドキュメントを確認すると、既存のS3バケットをインポートする場合、SIEM on Amazon ES の初期インストール時にのみ設定可能と記載があります。

すでにお持ちの S3 バケットを SIEM on Amazon ES の CloudFormation スタックに取り込み、AWS CDK で管理します。ログ取り込み用にS3 バケットポリシーを追加・修正します。S3 のバケットポリシーやその他のバケット設定は上書きされるのでご注意ください。SIEM on Amazon ES の初期インストール時にのみ設定可能です。 既存の S3 バケットから SIEM on Amazon ES にログを送信しつつ、S3 バケットポリシー等はご自身で引き続き管理する場合は、この手順はスキップしてください。

高度なデプロイ - 既存の S3 バケットの取り込み

そのため、デプロイ済みのSIEM on Amazon ESを削除してから、再度デプロイします。

削除方法は、cdk destroyをした後に、公式ドキュメントのクリーンナップに記載のリソースを手動で削除します。

> npx cdk destroy                                                                                                                                          122ms  日  7/ 4 21:39:50 2021

既存のログ収集用S3バケットのインポート

S3バケットのインポートの流れは以下の通りです。

  1. CloudFormation スタックに取り込みたい S3 バケットの名前を確認してください
  2. Github からソースコード一式を git clone するか、Github ここインポート用CloudFormationテンプレートをダウンロード
  3. GitHub から clone またはダウンロードした CloudFormationテンプレートの deployment/siem-on-amazon-elasticsearch-import-exist-s3bucket.template を編集する。BucketName の [change-me-to-your-bucket] をスタックに取り込みたい S3 バケット名に変更
  4. AWS マネジメントコンソールで CloudFormation に移動
  5. [スタック] のメニューから、右上のプルダウンメニューの [スタックの作成] から [既存のリソースを使用(リソースをインポート)] を選択
  6. [次へ]を選択して、[テンプレートの指定] 画面にて、編集したテンプレートの siem-on-amazon-elasticsearch-import-exist-s3bucket.template をアップロードし、[次へ] を選択
  7. [リソースを識別] 画面にて、[識別子の値] にスタックへ [インポートしたい S3 バケット名] を入力して、[次へ] を選択
  8. [スタックの詳細を指定] 画面にて、スタック名に [aes-siem] と入力して [次へ] を選択
  9. [概要をインポート] 画面にて、[リソースのインポート] を選択して完了
  10. 次のセクションの [AWS CDK によるデプロイ] の [5-3. その他の共通設定] で cdk.json を編集してください。スタックにインポートする S3 バケット名を s3_bucket_name.log に指定をしてください。

抜粋: 既存の S3 バケットの取り込み - 手順

それではやってみます。

CloudFormationで既存のリソースを使用(リソースをインポート)をクリックします。

既存リソースのインポートに必要なものを確認します。

BucketName の [change-me-to-your-bucket] をスタックに取り込みたい S3 バケット名に変更したdeployment/siem-on-amazon-elasticsearch-import-exist-s3bucket.templateをアップロードして、次へをクリックします。

識別子の値にインポートするS3バケット名を入力して、次へをクリックします。

スタックの名前にaes-siemと入力して、次へをクリックします。

最後に、インポートする内容を確認します。

どうやらインポートするS3バケットが別のスタックで管理されていることが原因でエラーが出力されています。インポートするS3バケットをデプロイしていたAWS CDKで、S3バケット関連の処理を削除して再度デプロイした後、もう一度確認してみます。

出力されていたエラーが消えたのを確認して、リソースをインポートをクリックします。

しばらく待つと、無事IMPORT_COMPLETEになりました。

cdk.jsonでインポートするS3バケットの名前を指定して、SIEM on Amazon ESをVPC上にデプロイします。

> cp -a cdk.json cdk.json.(date +"%Y%m%d") 

# インポートするS3バケットの名前を指定
> vi cdk.json 

# 差分を確認
> diff -u cdk.json.(date +"%Y%m%d") cdk.json

無事リソースがデプロイされました。インポートしたS3バケットのバケットポリシーがどのように変化しているのか確認してみます。 元々は、CloudTrail関連のバケットポリシーしかありませんでしたが、インポート後はELBや、GuardDutyなどのSIEM on Amazon ESでサポートされているサービスからのログ出力を受け付けるように変更されています。

それでは、Kibanaにログインしてログが読み込まれているか確認します。

ドロワーメニューより、Discoverをクリックして、読み込んだログの一覧を出力しても、No results match your search criteriと表示され、ログが読み込まれていないことが確認できます。

原因は、ログを正規化してAmazon ES へロードするLambda関数である、es-loaderの実行タイミングです。

es-loaderは、S3バケットにログがPUTされたタイミングで実行されます。
そのため、既にS3 バケットに保存されている過去のログについては、es-loaderは実行されず、Amazon ES にロードもされません。

対応として、es-loader をローカル環境で実行することで、S3 バケットに保存されている過去のログを SIEM on Amazon ES に取り込むことができます。

S3 バケットに保存された過去データの取り込み

環境準備

公式ドキュメントのこちらの手順に従い、環境準備を行います。

最初の準備項目に、1. Amazon ES へ通信ができる VPC 内に Amazon Linux 2 で EC2 インスタンスをプロビジョニングとありますが、今回は既にデプロイ済みのポートフォワーディング用のEC2インスタンスを使って行います。

まず、es-loader をローカル環境で実行できるようにポートフォワーディング用のEC2インスタンスのIAMロールにaes-siem-es-loader-for-ec2をアタッチします。

続いて、ポートフォワーディング用のEC2インスタンスにSSHで接続して、以下コマンドを実行します。

# 必要なモジュールのインストール
> sudo yum groups mark install -y "Development Tools"
> sudo yum install -y amazon-linux-extras
> sudo amazon-linux-extras enable python3.8
> sudo yum install -y python38 python38-devel git jq
> sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
> sudo update-alternatives --install /usr/bin/pip3 pip3 /usr/bin/pip3.8 1

# GitHub レポジトリからコードを clone
>git clone https://github.com/aws-samples/siem-on-amazon-elasticsearch.git

以下コマンドで、Pythonのモジュールをインストールします。

# 仮想環境のセットアップ
> cd siem-on-amazon-elasticsearch/source/lambda/es_loader/
> python3 -m venv .env
> source .env/bin/activate

# Pythonのモジュールをインストール
> pip3 install -r requirements.txt -U -t .

次に、AWSマネージメントコンソールで aes-siem-es-loader 関数に移動して、以下の 2 つの環境変数名と値をメモします。

  • ES_ENDPOINT
  • GEOIP_BUCKET

確認した環境変数をEC2インスタンスの環境変数に設定します。

> export ES_ENDPOINT=search-aes-siem-xxxxx.ap-northeast-1.es.amazonaws.com
> export GEOIP_BUCKET=aes-siem-<AWSアカウントID>-geo

S3 バケットのオブジェクトリストからの取り込み

es-loaderのディレクトリに移動して、S3 バケットからオブジェクトリスト (s3-list.txt) を作成します。

> cd
> cd siem-on-amazon-elasticsearch/source/lambda/es_loader/

export AWS_ACCOUNT=<AWSアカウントID>
export LOG_BUCKET=aes-siem-${AWS_ACCOUNT}-log
aws s3 ls ${LOG_BUCKET} --recursive > s3-list.txt

作成されたs3-list.txtを確認すると、オブジェクトのリストが作成されていることが分かります。

失敗したオブジェクトリストを指定して、 再度es-loader にログを流し込みます。

> ./index.py -b ${LOG_BUCKET} -l s3-list.txt.error.log

ログをKibanaで確認する

es-loader にログを流し込み終わったあと、再度ポートフォワーディングをした状態で、Kibanaにアクセスします。

Amazon Linux 2の /var/log/messagesのログの一覧も表示してみます。

Security Hubのログの一覧も表示してみます。

いずれも正常にログを読み込めていそうですね。

お試しでSIEM on Amazon ESを使ってみたいなら、Same-Region レプリケーションで読み込ませるのが良いかも

以下3パターンでSIEM on Amazon ESで既存S3バケットのログを分析してみました。

  1. Same-Region レプリケーション(SRR)を使用して、既存S3バケットのログSIEM on Amazon ESのログ収集S3バケットにレプリケーションする
  2. AWS DataSyncを使用して、既存S3バケットのログSIEM on Amazon ESのログ収集S3バケットにレプリケーションする
  3. 既存S3バケットをSIEM on Amazon ESにインポートする

個人的には、お試しでSIEM on Amazon ESを使ってみたいなら、Same-Region レプリケーション(SRR)を使用するパターンが良いのかなと思いました。

他のパターンと比べて良いと思ったポイントは以下の通りです。

  • DataSyncのパターンと比較して、レプリケーション間隔が短い
    • SSR: おおよそ15分以内にレプリケーション(オブジェクトのサイズなどによって、数時間かかることもある)
    • DataSync: 最も短くて1時間間隔でレプリケーション
  • S3バケットのインポートするパターンと比較して、以下のような手間がかからない
    • 上書きされるS3 のバケットポリシーやその他バケット設定の影響度合いの確認
    • AWS CDKの管理の手間
    • インポートされたS3バケット上のログを手動でes-loaderに読み込ませる

もちろん、SSRのパターンを選択した場合は、二重にS3のストレージの料金がかかりますし、レプリケーションをする際の PUT リクエストにも課金が発生します。

そのため、課金額を抑えたいという方、構成をシンプルにされたい方は、S3バケットのインポートするパターンを選択されると良いと思います。

このブログが誰かの助けになれば幸いです。
