Cloud services to hold Asset Bundle

A normal webspace would be enough to store your AssetBundles and load them in your app accordingly. For testing you can just register for a free webspace or if you have an old dropbox account, you might be able to use it too. In general this is a the forum for Unity Cloud Build, so your question better belongs into another forum section as it is not really related to Unity Cloud Build. If you like I can move the thread for you so you get a better attention.

However, I made an example Asset Bundle Demo which shows how to load Asset Bundles from a webserver. It also works using Unity Cloud Build, that's why it is in this forum section but you can also use it locally of course. Just have a look at Asset Bundle Demo. I hope that helps
