I migrated a big data stack to GCP from AWS. Reasons: GCP has better documentation, the AWS console and various services confuse the heck out of me (I guess I'm getting too old), and the security integration between GCP services saves a huge amount of time. It's super easy and very fast to used the Google Compute Engine VMs. Given that the company I work for uses G Suite, it's a piece of cake to implement SSO and other integration pieces. It's also cheaper for us than AWS and more performant.
