Building a scalable geofencing API on Google’s App Engine


via Google Developers Blog: Building a scalable geofencing API on Google’s App Engine.

Google’s Cloud Platform offers a great set of tools for creating easily scalable applications in the cloud. In this post, I’ll explore some of the special challenges of working with geospatial data in a cloud environment, and how Google’s Cloud can help. I’ve found that there aren’t many options to do this, especially when dealing with complicated operations like geofencing with multiple complex polygons. You can find the complete code for my approach on GitHub.

Geofencing is the procedure of identifying if a location lies within a certain fence, e.g. neighborhood boundaries, school attendance zones or even the outline of a shop in a mall. It’s particularly useful in mobile applications that need to apply this extra context to someone’s exact location. This process isn’t actually as straight forward as you’d hope and, depending on the complexity of your fences, can include some intense calculations and if your app gets a lot of use, you need to make sure this doesn’t impact performance.

In order to simplify this problem this blogpost outlines the process of creating a scalable but affordable geofencing API on Google’s App Engine.

And the best part? It’s completely free to start playing around.
