Google Cloud Service Quick Reference
GCP organises services around Compute (GCE, GKE, Cloud Run, App Engine, Cloud Functions), Storage (Cloud Storage, Persistent Disk, Filestore), Databases (Cloud SQL, Spanner, Firestore, Bigtable, BigQuery), and Networking (VPC, Cloud Load Balancing, Cloud CDN, Cloud Interconnect).
