Serverless Computing

 Serverless Computing

Serverless computing is a cloud computing execution model in which the cloud provider dynamically manages the allocation of machine resources. Instead of running your code on a dedicated server or virtual machine, your code runs in a serverless environment that automatically scales and manages the infrastructure.

One popular serverless computing platform is AWS Lambda. Here's an example of a Lambda function that takes in a JSON payload, performs a simple calculation, and returns the result:

import json

def lambda_handler(event, context):

    x = event['x']

    y = event['y']

    result = x + y

    return {

        'statusCode': 200,

        'body': json.dumps({'result': result})

    }

This function can be triggered by an API Gateway event, allowing it to be used in a serverless web application.
