(mbl302) mastering synchronization across mobile devices, login providers, and the web | aws...
DESCRIPTION
In the past, content and preferences would be moved to the device. Now devices are just a window to content and services that live in the cloud. The cloud enables your content and preferences to follow you wherever you go. You have the ability to transition between your phone, tablet, and laptop and seamlessly pick up where you left off. With Amazon Cognito, you can synchronize user data across mobile OS/devices and bridge the web world with the mobile world. In this session, learn how you can implement sync in Android, iOS, and JavaScript so you can deliver a ''WOW'' customized user experience to your customers. We show you how to integrate with Amazon Cognito to sync with mobile devices and the web and delve into some of the nuances of syncing, such as conflict resolution and account merging.TRANSCRIPT

Implementing a user profile that syncs across devices, OS, apps is hard.
Concrete Software has been making hit mobile games
like Jellyflop and PBA Bowling Challenge since 2003.
With Amazon Cognito, We
can build games much faster
and provide great user
experience to our customers.

“• Provide a seamless user experience across devices
and platforms to our users.
• Store save games in the cloud and synchronize them
across all of a user’s devices without creating or
hosting a backend.
The Challenge
The solution
• Amazon Cognito helps us securely access our AWS
resources.
• Cognito Sync gives us flexibility to save data in the
cloud, and cache it on a user’s devices, without
managing any backend infrastructure.
• Store App Data, Preferences and State
• Work Offline
• No Backend
User
Data
Identity Pool
• Identity Pool: Pool of app users. Can be
shared across apps.
• Identity: An individual user. Consistent
across identity providers. Can be a guest
user.
• Dataset: Per user grouping of data. The
most granular level of sync. Up to 1 MB.
• Record: Key/Value pair.
