Synchronize data across devices : Amazon Cognito (Sync)

Cognito Cloud Save and Sync

User Data Storage and Sync

Any Platform

iOS/Android/FireOS

Store App Data, Preferences and State Save app and device data to the cloud and merge them after login

Cross-device Cross-OS Sync Sync user data and preferences across devices with one line of code

Work Offline Data always stored in local SQLite DB first. Works seamlessly when intermittent or no connectivity

k/v data

Identity pool

Amazon Cognito SyncOffline: The client SDK manages a local SQLite data store to allow the app to work even when connectivity is not available.

Fast: The methods to read and write data only interact with the local SQLite database. Intelligent Sync: The sync method compares the local version of the data to the cloud sync store, pushes up deltas and pulls down new changes. Flexible Conflict resolution: The sync method first reads the changes then writes its local changes to the cloud sync store By default Cognito assumes that the last write wins. Developers can override and implement their own conflict resolution programmatically

Local SQLite Cache

Use case: Game State

Concrete Software builds cross platform mobile games

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.

Keith A. Pichelman CEO, Concrete Software

”

“• 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.

Outplay Entertainment – Amazon S3 Connector via AWS Mobile SDK

Outplay Entertainment is mobile-focused game developer on a mission to deliver fun, free and innovative games for

smartphones, tablets, and social networks.

With Amazon S3 connector, we can improve the users experience by

dynamically downloading game assets in the background. No long up-front

delays for our users.

Douglas Hare CEO, Outplay Entertainment

”

“ • Improved User Experience. Using the Mobile SDK, they can download the game assets in background while the user starts playing the game. No limits on downloading extra assets.

• Dynamic updates. They can update the assets dynamically and avoid AppStore release cycles.

• Unquestioned Scalability. Different assets for multiple screen densities go up to 170 MB+. By storing this data on S3 and directly downloading to the mobile device, they can scale seamlessly.

• Excellent Performance. Highest resolution devices end up downloading about 90MB of extra content.
