I am currently developing an Evernote-or-Dropbox-like app. Can anyone here suggest a free cloud platform I could use ? I know there are few paid cloud platform like Microsoft Windows Azure or Amazon EC2, but I am looking for a free one.
You can use QuickBlox, which is a cloud hosted platform to simplify your mobile app backend development. Try the Content Sample, you can use upload files, and create your own data-types. QuickBlox uses Amazon EC2 Platform.
