What it does
AlloyDB for PostgreSQL is Google's managed PostgreSQL-compatible database service. Its documented console workflow creates a cluster and primary instance, then uses AlloyDB Studio to create a database, run SQL, and inspect results. Google also documents read pools, cross-region replication, analytical features, and vector capabilities. Compute, storage, backup, and network charges are billed separately.
The official quickstart offers a concrete evaluation path: select or create a Google Cloud project, enable billing and the required APIs, obtain the documented IAM roles, create a cluster and primary instance, then use AlloyDB Studio to create a database, table, and sample rows. It also explains how to delete the cluster afterward. The guide uses a single-zone instance to minimize quickstart costs and explicitly says that configuration is not recommended for production.
AlloyDB is a hosted service for teams that want PostgreSQL compatibility with Google's managed cluster and storage model. The pricing page describes usage-based charges for compute, memory, storage, backups, networking, and extended support; prices vary by region and resource configuration. It documents a 30-day free-trial cluster with limits of up to 1 TB of data, an 8-vCPU primary instance, and an 8-vCPU single-node read pool. Those trial limits are distinct from ongoing paid usage. The product page also describes AlloyDB Omni as a separate downloadable edition; this listing is for the Google Cloud service.
