I am working on a side project. I may use GCP or AWS for it.
tldr of the system : Create a web ui to process input files and generate a tabular output giving the link to the dashboard .
I have a bunch of files generated , about 2GB in size in total , Account ID is the high level directory and inside each account there 50 log files each having specific content .
I want to create a UI using Angular framework . Using the UI I will upload the files to GCS /AWS S3 . Then the backend should trigger complex backend scripts, written will be written in Python or Java and then output file is generated. Using the output file a dashboard with few images embedded is generated.
In the end the UI should have a table which should indicate status of processing to COMPLETE and in another column show point to url of the dashboard.
I want to deal with least amount of security work as I want to avoid studying Oauth 2.0 authentication .
Few additional questions , non-system design questions =>
