It's a syncing service first (and you can optionally opt in to get an email-id). The website provides you webapps for your synced iCloud contacts, calendars, notes, reminders and iWork documents and for "Find your iDevice". For other applications it serves as cloud "storage" but there's no web interface for those.
The app icons are equivalent to iOS app grid and the little cloud button serves as the home button for the "Apps"
