Secure Data Sharing: AWS Lambda Writing to S3 Across Accounts

1. 1Create an IAM role in the source account with permissions to write to S3
2. 2Configure the IAM role to assume a role in the target account
3. 3Write an AWS Lambda function to write data to S3 using the assumed role
4. 4Test the Lambda function to ensure data is written successfully to S3 in the target account
5. 5Configure S3 bucket policy to allow cross-account access
