Lambda in AWS

 Lambda in AWS

Lambda is a serverless compute service that allows you to run code without provisioning or managing servers. Here is an example of how to create a Lambda function using the AWS SDK for Python (boto3):

python

import boto3

lambda_client = boto3.client('lambda')

response = lambda_client.create_function(

    FunctionName='my-function',

    Runtime='python3.6',

    Role='arn:aws:iam::123456789012:role/lambda-role',

    Handler='handler.lambda_handler',

    Code={

        'ZipFile': open('lambda_function.zip', 'rb').read()

    },

    Description='My first Lambda function'

)

This code creates a Lambda function named "my-function" that runs on Python 3.6, uses a specified role, and executes a function called "handler.lambda_handler". It also specifies the code for the function, which is packaged as a ZIP file.
