## How Google AlloyDB pricing works

AlloyDB is PostgreSQL-compatible and prices the database instance by its resources: you pay per vCPU and per GB of memory, by the hour, at a fixed 8 GB per vCPU across one machine family from 2 to 128 vCPU, shown here as a monthly figure (hourly rate x 730).

An AlloyDB cluster runs a primary instance plus optional read-pool instances, and you pay for each instance's compute. Storage is usage-based (it scales automatically rather than being pre-provisioned) and, along with backups and networking, is billed separately and varies by region. The interactive table at https://www.bytebase.com/dbcost/alloydb-pricing lets you switch region and sort by any column.

AlloyDB has no committed-use discount shown (Google's commitments are spend-based, not per instance). For standard managed databases see Cloud SQL, Amazon RDS, and Amazon Aurora.

## Google AlloyDB pricing FAQ

### How much does Google AlloyDB cost?

On-demand AlloyDB starts around $227/month for the smallest machine (alloydb-2, 2 vCPU / 16 GB) and scales to over fourteen thousand per month for the largest 128-vCPU shape (us-central1). That is one instance's compute only - storage, backups, and networking are billed separately. AlloyDB has no free tier.

### How is AlloyDB priced?

AlloyDB is priced per vCPU-hour plus per GB-of-memory-hour, at a fixed 8 GB per vCPU across one machine family from 2 to 128 vCPU. You pay per instance in the cluster - the primary and each read-pool node.

### Does the price include storage?

No. The price is for the database instance (compute) only. AlloyDB storage is usage-based and scales automatically, and it - along with backups and networking - is billed separately by Google Cloud.

### How does AlloyDB pricing compare to Cloud SQL?

AlloyDB costs more per vCPU than Cloud SQL and targets demanding transactional and analytical PostgreSQL workloads. For standard managed PostgreSQL or MySQL, Cloud SQL is usually cheaper.

### Does AlloyDB have committed-use discounts?

Yes, but they are spend-based (a 1- or 3-year commitment to a dollar amount of usage) applied at the billing account, not tied to a specific instance, so they cannot be shown per row.

### Is AlloyDB pricing the same in every region?

No. Rates vary by Google Cloud region; us-central1 (Iowa) is usually among the cheapest.
