Deploying a Secure SFTP-to-S3 Pipeline Using AWS CDK

Infrastructure as Code using AWS CDK to deploy an SFTP server on EC2 integrated with S3 — combining automation, security, and scalability in a DevOps-friendly stack.

🧱 What It Does

This project provisions the following resources using AWS CDK (in Python):

• A VPC with public/private subnets
• An S3 bucket for file storage
• An IAM Role with access to S3
• An EC2 instance to run the SFTP server (SimpleSFTP)
• All necessary networking and security group settings

The goal is to demonstrate AWS CDK in a practical portfolio use case, combining two existing components:

• SimpleSFTP
• sftp2s3

🔗 eks-ec2-cdk-react-dns-demo:
A more advanced CDK portfolio demo — provisions an EKS cluster with EC2 nodes, deploys containerized apps, and configures DNS via Route 53.
Ideal for showcasing full-stack infrastructure skills alongside this SFTP pipeline.

🐳 Docker Image

The SFTP server used in this project is available as a public Docker image:

🔗 daviguides/simple-sftp on Docker Hub

This image is automatically pulled and started on the EC2 instance during provisioning via user_data.
