Multiple Devices
App Settings
App State
Users will likely have multiple devices
• Desktop, Laptop
• Tablet
• Phone
Save settings to the cloud so that applications that run on multiple
devices have consistent configuration. When user changes a setting
on one device, it should be reflected on their other devices
Application state should be persisted to the cloud and consumed by
all devices:
• Current page in a document
• Current level in a game
• Etc.
