AWS Lambda Hello World

Project Overview

This project demonstrates the deployment of a basic AWS Lambda function using the AWS Management Console.

The function was written in Python and tested directly from the Lambda console. CloudWatch Logs were used to monitor execution and verify successful invocation.

Objectives

• Learn AWS Lambda fundamentals
• Create a serverless function
• Deploy Python code
• Test the function
• Monitor execution using CloudWatch Logs

---

Services Used

• AWS Lambda

Step 2 - Hello World Function

The default code was replaced with a simple Hello World Lambda function.

Example code:

def lambda_handler(event, context):

    print("Hello from AWS Lambda")

    return {
        "statusCode":200,
        "body":"Hello from AWS Lambda"
    }

---

Step 3 - Test Event

A test event was created inside the Lambda console to invoke the function.

---

Step 4 - Monitor Execution

The Monitor tab was used to observe function execution metrics.

---

Step 5 - CloudWatch Logs

CloudWatch Logs confirmed that the Lambda function executed successfully.
