+# Langflow on AWS
+
+**想定時間**: 30 分
+
+## 説明
+Langflow on AWS では、 [AWS Cloud Development Kit](https://aws.amazon.com/cdk/?nc2=type_a) (CDK) を用いて Langflow を AWS 上にデプロイする方法を学べます。
+このチュートリアルは、AWS アカウントと AWS に関する基本的な知識を有していることを前提としています。
+
+作成するアプリケーションのアーキテクチャです。
+![langflow-archi](./img/langflow-archi.png)
+AWS CDK によって  [Application Load Balancer](https://aws.amazon.com/elasticloadbalancing/application-load-balancer/?nc1=h_ls)、[AWS Fargate](https://aws.amazon.com/fargate/?nc2=type_a)、[Amazon Aurora](https://aws.amazon.com/rds/aurora/?nc2=type_a) を作成します。
+Auroraのシークレットは [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/?nc2=type_a) によって管理されます。
+Fargate のタスクはフロントエンドとバックエンドに分かれており、サービス検出によって通信します。
+リソースをデプロイするだけであれば、上記の各サービスについて深い知識は必要ありません。
+
+# 環境構築とデプロイ方法
+1. [AWS CloudShell](https://us-east-1.console.aws.amazon.com/cloudshell/home?region=us-east-1)を開きます。
+
+1. 以下のコマンドを実行します。
+    ```shell
+    git clone https://github.com/aws-samples/cloud9-setup-for-prototyping
+    cd cloud9-setup-for-prototyping
+    ./bin/bootstrap
+    ```
+
+1. `Done!` と表示されたら [AWS Cloud9](https://us-east-1.console.aws.amazon.com/cloud9control/home?region=us-east-1#/) から `cloud9-for-prototyping` を開きます。
+    ![make-cloud9](./img/langflow-cloud9.png)
+
+1. 以下のコマンドを実行します。
+    ```shell
+    git clone -b aws-cdk-dev2 https://github.com/kazuki306/langflow
+    cd langflow/scripts/aws
+    cp .env.example .env # 環境設定を変える場合はこのファイル(.env)を編集してください。
+    npm ci
+    cdk bootstrap
+    cdk deploy
+    ```
+1. 表示される URL にアクセスします。
+    ```shell
+    Outputs:
+    LangflowAppStack.NetworkURLXXXXXX = http://alb-XXXXXXXXXXX.elb.amazonaws.com
+    ```
+1. サインイン画面でユーザー名とパスワードを入力します。`.env`ファイルでユーザー名とパスワードを設定していない場合、ユーザー名は`admin`、パスワードは`123456`で設定されます。
+    ![make-cloud9](./img/langflow-signin.png)
+
+# 環境の削除
+1. `Cloud9` で以下のコマンドを実行します。
+    ```shell
+    bash delete-resources.sh
+    ```
+
+
+1. [AWS CloudFormation](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/getting-started)を開き、`aws-cloud9-cloud9-for-prototyping-XXXX` を選択して削除します。

+# Deploy Langflow on AWS
+
+**Duraration**: 30 minutes
+
+## Introduction
+In this tutorial, you will learn how to deploy langflow on AWS using [AWS Cloud Development Kit](https://aws.amazon.com/cdk/?nc2=type_a) (CDK).
+This tutorial assumes you have an AWS account and basic knowledge of AWS.
+
+The architecture of the application to be created:
+![langflow-archi](./img/langflow-archi.png)
+
+[Application Load Balancer](https://aws.amazon.com/elasticloadbalancing/application-load-balancer/?nc1=h_ls), [AWS Fargate](https://aws.amazon.com/fargate/?nc2=type_a) and [Amazon Aurora](https://aws.amazon.com/rds/aurora/?nc2=type_a) are created by AWS CDK.
+The aurora's secrets are managed by [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/?nc2=type_a).
+The Fargate task is divided into a frontend and a backend, which communicate through service discovery.
+If you just want to deploy resources, you do not need in-depth knowledge of each of the above services.
+
+# How to set up your environment and deploy langflow
+1. Open [AWS CloudShell](https://us-east-1.console.aws.amazon.com/cloudshell/home?region=us-east-1).
+1. Run the following commands in Cloudshell:
+    ```shell
+    git clone https://github.com/aws-samples/cloud9-setup-for-prototyping
+    cd cloud9-setup-for-prototyping
+    ./bin/bootstrap
+    ```
+1. When you see `Done!` in Cloudshell, open `cloud9-for-prototyping` from [AWS Cloud9](https://us-east-1.console.aws.amazon.com/cloud9control/home?region=us-east-1#/).
+    ![make-cloud9](./img/langflow-cloud9-en.png)
+1. Run the following command in the Cloud9 terminal.
+    ```shell
+    git clone -b aws-cdk-dev2 https://github.com/kazuki306/langflow
+    cd langflow/scripts/aws
+    cp .env.example .env # Edit this file if you need environment settings
+    npm ci
+    cdk bootstrap
+    cdk deploy
+    ```
+1. Access the URL displayed.
+    ```shell
+    Outputs:
+    LangflowAppStack.NetworkURLXXXXXX = http://alb-XXXXXXXXXXX.elb.amazonaws.com
+    ```
+1. Enter your user name and password to sign in. If you have not set a user name and password in your `.env` file, the user name will be set to `admin` and the password to `123456`.
+    ![signin-langflow](./img/langflow-signin.png)
+
+# Cleanup
+1. Run the following command in the Cloud9 terminal.
+    ```shell
+    bash delete-resources.sh
+    ```
+1. Open [AWS CloudFormation](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/getting-started), select `aws-cloud9-cloud9-for-prototyping-XXXX` and delete it.
