Mobile Apps for Location-based Engagement
Publication date: July 8, 2021 (Diagram history)
This architecture is built around Amazon Location Service features such as maps, trackers, and geofence collections. Mobile users carry their devices all the time and everywhere. Adding location awareness to apps enables you to offer an enhanced experience, such as sending real-time messages and information based on user location.
Mobile Apps for Location-based engagement
-
A web app deployed by AWS Amplify is used by operations and business users to create messages, business rules for engagements, and geofences that initiate messages.
-
Operations are performed via a GraphQL API provided by AWS AppSync, to interact with a single API and a standardized access layer. The web app leverages Amplify libraries to make requests to AWS AppSync.
-
Data for messages and rules is stored in DynamoDB tables.
-
When creating a rule for engagements, an AWS Lambda function also creates a geofence on a Geofence collection.
-
The mobile app leverages Amplify libraries to make requests to the AWS AppSync API. Geolocations are sent to a tracker to follow the device’s position.
-
Position is evaluated against geofences. Events are initiated on Amazon EventBridge when a device enters or exits a geofence.
-
A Lambda function processes events and notifies users either via AWS AppSync or Amazon Pinpoint.
