AlloyDB, Spanner

These are often grouped as "Premium/Advanced" databases, but they serve different needs:

  • AlloyDB:

    • What it is: A fully managed, PostgreSQL-compatible database that is "supercharged." It separates storage from compute to be much faster and more scalable than standard CloudSQL. It is Google's answer to Amazon Aurora.

    • AWS Equivalent: Amazon Aurora (PostgreSQL compatible)

    • Azure Equivalent: Azure Database for PostgreSQL (Flexible Server) or Azure Cosmos DB for PostgreSQL (formerly Citus)

  • Cloud Spanner:

    • What it is: A global, horizontally scalable relational database. It combines the structure of SQL with the infinite scale of NoSQL. It is designed for mission-critical apps that need to run across multiple continents simultaneously with zero downtime.

    • AWS Equivalent: Amazon Aurora Global Database or Amazon DynamoDB (though Dynamo is NoSQL, it matches the scale).

    • Azure Equivalent: Azure Cosmos DB (matches the global distribution/scale).
