# Langflow on AWS
# Deploy Langflow on AWS
Langflow on AWS は、 Langflow を AWS 上に展開する Project になります。
この Branch では、AWS CDK を用いて 各種 Dockerfile からコンテナイメージを ECR に展開し、ECS、Aurora MySQL を用いて Langflow を構築します。
In this tutorial, you will learn how to deploy langflow on AWS using CDK.
# デプロイ
[CloudShell](https://us-east-1.console.aws.amazon.com/cloudshell/home?region=us-east-1)を開きます。
This tutorial assumes you have an AWS account and basic knowledge of AWS.
以下のコマンドを実行します。
# How to set up your environment and deploy langflow
