Setup AWS lambda beginner example with step by step guide

Beginner example for setting up an AWS Lambda function using the AWS Management Console:

1. Log in to your AWS account and navigate to the AWS Management Console.
2. Click on the “Lambda” service from the list of services.
3. Click on the “Create Function” button.
4. Choose the “Author from scratch” option.
5. Give your function a name and choose the runtime for your function (e.g., Python, Node.js, etc.).
6. In the “Function code” section, you can either write your function code directly in the console or upload a ZIP file containing your code.
7. In the “Handler” field, specify the name of your function and the file name that contains your function code (e.g., my_function.handler).
8. Under “Basic settings”, you can configure the memory and timeout for your function.
9. Click on the “Create function” button to create your function.

Here’s an example code for a simple AWS Lambda function in Python:

import json

def lambda_handler(event, context):
    # Your code goes here
    message = "Hello, World!"
    return {
        'statusCode': 200,
        'body': json.dumps(message)
    }

This function simply returns a “Hello, World!” message as a JSON response with a status code of 200.

Once you’ve created and tested your function, you can trigger it using various events, such as API Gateway, S3 events, or AWS CloudWatch events.
