aws-cdk.aws-s3objectlambda-alpha

Create a mini-application that leverages the AWS S3 Object Lambda feature to dynamically transform objects stored in an Amazon S3 bucket before they are served to end-users. This application will demonstrate how to use the 'aws-cdk.aws-s3objectlambda-alpha' package to set up an S3 Object Lambda Access Point and configure it to execute a Lambda function on-demand to modify content as it's retrieved from S3. Here’s a step-by-step guide on what your application should achieve:

1. **Setup Environment**: Ensure you have Python and AWS CDK installed. Install the required package `aws-cdk.aws-s3objectlambda-alpha` using pip.
2. **Define S3 Bucket**: Create an S3 bucket where the original files will be stored.
3. **Configure S3 Object Lambda Access Point**: Use the `aws-cdk.aws-s3objectlambda-alpha` package to define an S3 Object Lambda Access Point that points to the previously created S3 bucket.
4. **Integrate Lambda Function**: Attach a custom AWS Lambda function to the S3 Object Lambda Access Point. This Lambda function should modify the content of the objects fetched from the S3 bucket, for example, adding watermarks to images or encrypting text files.
5. **Deploy Application**: Deploy the CDK stack to AWS. This deployment will create all necessary resources including the S3 bucket, S3 Object Lambda Access Point, and the associated Lambda function.
6. **Test Functionality**: Upload a sample file to the S3 bucket. Then, access this file through the S3 Object Lambda Access Point URL and verify if the modifications made by the Lambda function are applied correctly.

**Suggested Features**:
- Implement different types of transformations based on file type (e.g., add watermarks to images, obfuscate sensitive data in text documents).
- Include logging mechanisms within the Lambda function to track which objects were modified and when.
- Provide a simple web interface or CLI tool that allows users to upload files to the S3 bucket and view them via the S3 Object Lambda Access Point.

This project aims to showcase the flexibility and power of S3 Object Lambda for real-time content transformation, enhancing security and customization of data served from S3.
