A few months back I posted my experiments deploying serverless Earth Engine functions using infrastructure-as-code with Pulumi. Here, I’m building on that code to add a Redis instance that will allow us to cache server-side computations, reducing the number of EE calls and speeding up responses. The Goal I’m going to build on the original demo function, which computed the cloud cover of the most recent Landsat 9 image (you can still run it here).
