API Development Using AWS Serverless Architecture

I recently had the opportunity to work on an AWS-based Serverless architecture solution. This is for ZIP files processing requirements. At a high level, the requirements expected to be delivered from AWS are summarized below:

1. Create a final output zip file from the contents of source zip files and arrange them in a specific hierarchy of folder structure. There are 2 Systems that will make source ZIP files available in the S3 bucket.
2. Delete the set of files requested by Pega.
3. Transfer the output zip file to the external SFTP server.
