Create a pipeline for converting pointcloud files

We need to develop a cloud pipeline to convert point cloud files that will take point cloud files from S3, process them with Entwine -https://entwine.io/-, and PDAL - https://pdal.io/ - and place the converted files into another S3 bucket.

Ideally, the process should be done using AWS lambda or a similar container scalable solution. Suggestions are welcomed.
