 * Just speculating, but a [serverless pipeline](https://github.com/aws-samples/amazon-rekognition-video-analyzer) appears to be where companies are headed for routine compute tasks, whilst providing a Jupyter notebook approach for custom analysis.
 * Traditional data formats aren't designed for processing, so new standards are developing such as [cloud optimised geotiffs](http://blog.digitalglobe.com/developers/cloud-optimized-geotiffs-and-the-path-to-accessible-satellite-imagery-analytics/) and [zarr](https://github.com/zarr-developers/zarr)
 
+## Batch processing
+* Google provide training on how to use Apache Spark on Google Cloud Dataproc to distribute a computationally intensive (satellite) image processing task onto a cluster of machines -> https://google.qwiklabs.com/focuses/5834?parent=catalog
