Cloud Spanner
ELI5 — The Vibe Check
Google built a database that's both relational AND globally distributed, which is supposed to be impossible — like a car that's also a boat AND a plane. Cloud Spanner gives you SQL, ACID transactions, AND horizontal scaling across the planet. It's what happens when Google throws infinite engineering at the CAP theorem.
Real Talk
Google Cloud's globally distributed, strongly consistent relational database service. It combines the benefits of relational structure with horizontal scalability using TrueTime (atomic clocks and GPS) for external consistency. Supports SQL, schemas, and ACID transactions across regions.
When You'll Hear This
"Cloud Spanner handles our global inventory system — ACID transactions across 5 continents." / "We pay a premium for Spanner, but the alternative was building our own distributed consensus layer."
