Perhaps I'm on the wrong approach, however here is what I'm trying to do on AWS: I have a collection of OpenDocument files (calc, base) and I need to share those to other people; each user should access an instance of the file, meaning he/she can use its functionalities but not modify and more importanty he/she cannot download the file.
I tried setting up permission using the AWS policy generator, but once the file is accessible it can be modified and/or downloaded.
Is there a more simple solution for this?
If you deal with files, users will be able to download or access. So, You should be looking at a VM/VDI solution to enable them to only 'Use' but not download or copy.
eg: AWS has App Streaming which I think serves your use case.
