I'm starting to plan a new web app for the company that I'm currently working for. The idea is to create a web app where the user will do all the basic operations (upload, delete, update, etc.) on Amazon Glacier. Users basically will admin the account of AWS Glacier, create vaults, tags, upload files, delete files, etc.. all the options AWS Glacier has to offer.
There will be several users, each user with different AWS Glacier accounts and with unique AWS configurations.
Another important aspect is the security of the information of each user (the AWS Glacier credentials). I believe I'll need to encrypt this information of each user somehow.
I'm having second thoughts if I should develop this project with Django or .NET. What do you think? Or maybe is there a third option I should consider besides Django and .Net?
