I work for Pivotal. Our internal development environments mostly run on GCP, after migrating from AWS. We chose it because (a) it performs much better and (b) Google would give us the time of day, unlike Amazon. As it happens BOSH made that process manageable for most individual teams because of its design. We do however spend significant amounts with Azure and AWS, to test our various systems on this platforms. PKS came to GCP first because the opensource feedstock, CFCR (née Kubo) was co-developed by Pivotal and Google and was first developed on GCP. As for chunk projection, I can put you in touch with relevant teams for feedback -- jchester@pivotal.io.
