Today, Amazon Location Service announced a price reduction of up to 75% for tracking position writes and up to 70% for geofence evaluations, depending on your usage levels. Developers can use Amazon Location Trackers to track the current and historic location of devices in order to optimize operations such as asset management and delivery dispatch. They can evaluate location updates from their devices against their geofences to detect and act when a tracked device enters or exits a geographical boundary. This event-driven setup makes it easy for applications to scale in size and sophistication as needed.
