Using the example I have worked with, BigQuery, it appears Google is building platforms specifically for the cloud. BQ does not use the context of an instance, whereas RedShift is simply a column store hosted on specific VM sizes. It takes time to build new solutions compared to simply moving the hosting location. I don't expect this is universal across all products, but one example.
