How to integrate S3 with AWS Lambda for processing uploaded files?

To integrate S3 with AWS Lambda for processing uploaded files, you can follow the steps below:

1. Create an S3 bucket where your files will be uploaded.
2. Create an AWS Lambda function that will be triggered whenever a file is uploaded to the S3 bucket. You can do this by selecting "S3" as the trigger source for your Lambda function and selecting the appropriate bucket and event type (e.g., ObjectCreated).
3. Write the code for your Lambda function that will process the uploaded file. You can use the AWS SDK for JavaScript or any other supported languages to access the S3 bucket, read the uploaded file, and perform any necessary processing.
4. Test your integration by uploading a file to the S3 bucket and verifying that your Lambda function is triggered and processes the file correctly.

By following these steps, you can easily integrate S3 with AWS Lambda for processing uploaded files and perform any necessary actions or data processing on the uploaded files.
