Migrate local platform installation to cloud

Is there a difference between installing PortableApps in the cloud as opposed to locally? Or is it that installation in the cloud is simply a *regular* installation of PortableApps on some cloud-synced folder? If the latter is true, then this has achieved nothing, as applications build temporary files, and there will be conflicts between these temporary files! An installation in the cloud should make sure that temporary files are *not synced*!
