🚀 AWS S3 Versioning & Lifecycle Rules — Hands‑On Project

andrewesley1211 — Wed, 28 Jan 2026 15:24:11 +0000

A practical demonstration of enabling S3 Versioning and configuring Lifecycle Rules to automate object transitions, enforce retention, and optimize storage costs in AWS. This project reflects real‑world cloud engineering practices and is ideal for learning, documentation, and portfolio presentation.

📌 Overview
This project walks through:

Creating an S3 bucket
Enabling bucket versioning
Uploading and modifying objects
Creating lifecycle rules for transitions and expirations
Understanding how versioning and lifecycle automation work together

Building a serverless function in AWS

🧱 What I Built
I created a simple Lambda function that returns a message like:
Hello, Andre! Your serverless function is working.

The function runs instantly when someone hits the API URL. No servers. No maintenance. Just code.

🪜 Step-by-Step: Building the Serverless Function

Open AWS Lambda
Log in to AWS
Search for Lambda
Click Create function
Create the Function
Choose Author from scratch
Name: myServerlessFunction
Runtime: Node.js 20.x
Leave everything else as default
Click Create function
Add the Code Replace the default code with this:

export const handler = async (event) => {
const name = event.queryStringParameters?.name || "World";

return {
statusCode: 200,
body: JSON.stringify({
message: Hello, ${name}! Your serverless function is working.,
}),
};
};

Click Deploy.

Add an API Gateway Trigger This makes your function accessible through a URL.
Scroll to Function overview
Click Add trigger
Choose API Gateway
Select Create a new API
API type: HTTP API
Security: Open
Click Add AWS will generate a public endpoint URL.
Test the Function Open the URL in your browser:

🧠 What I Learned
Building this project helped me understand:

How AWS Lambda works
How serverless functions scale automatically
How API Gateway exposes functions through HTTP endpoints
How to pass query parameters into a Lambda function
How to deploy backend logic without provisioning servers This is a great beginner project because it teaches the fundamentals of serverless architecture without overwhelming complexity.
