We (Sojern) moved to 100% GCP as well this month, admittedly not nearly at the same scale as Spotify, but we did.  Other than some growing pains - that GCP team is already aware of - this has been a very smooth migration for us.<p>We use Google Cloud {Storage, BigTable, Container Engine, BigQuery, Monitoring, DNS, Compute} and may be some services I&#x27;m missing.  I&#x27;d be happy to answer any questions.
