Amazon Cognito Sync
Amazon Cognito Sync provides an AWS service and client library
that enable cross-device syncing of application-related user data.
High-level client libraries are available for both iOS and
Android. You can use these libraries to persist data locally so
that it's available even if the device is offline. Developer
credentials don't need to be stored on the mobile device to access
the service. You can use Amazon Cognito to obtain a normalized
user ID and credentials. User data is persisted in a dataset that
can store up to 1 MB of key-value pairs, and you can have up to 20
datasets per user identity.
