My view is that there are areas where GCP is better and areas where AWS is better. AWS has a much bigger community, and better business continuity story. GCP has a better developer experience and more uniquely-amazing best-in-class products (e.g. Spanner, Cloud Run, BigQuery). In the end, I don't believe Google will shut down GCP.

At Coherence (withcoherence.com) - I'm a cofounder - we deliver a developer platform that lets use use either cloud in a developer-friendly way. It also gives you some protection against lock-in to either cloud.
