Enterprises rely on mission-critical operational databases where performance slowdowns simply aren’t an option. Yet when even a few agents execute dense reasoning loops, the unpredictable surge in queries can easily overwhelm traditional architectures.

Today, we’re announcing that AlloyDB delivers PostgreSQL for agents (in preview), enabling real-time data access without compromising your mission-critical systems. AlloyDB now scales to dynamic agent bursts by provisioning sandboxed database instances in seconds, enabling full workload isolation. You can cost-effectively run your agents at any scale — from a few agents to millions of agents — and the instances automatically spin down when agents finish. With this announcement:

AlloyDB now features an agentic database architecture engineered to scale PostgreSQL to thousands of serverless database instances that have up-to-the-second read-only access to production. These instances remain fully separated from the primary, standby, and read replica instances where production workloads run.

Each of these instances access real-time data in the database backed by a unified storage layer in Colossus, Google’s exabyte-scale distributed storage system . This helps agents achieve sub-millisecond I/O, and terabit-per-second aggregated scan throughput, supporting over 3 million queries per second.

These instances utilize the full AlloyDB PostgreSQL engine, providing access to every index, the full capability of SQL, and comprehensive vector, full-text, and spatial search. Agents can also leverage BigQuery and Spark to run lakehouse analytics without requiring complex ETL pipelines.

When agents complete their tasks, these instances scale right back to zero, thus reducing your cloud spend by billing only for active reasoning loops.

With AlloyDB for PostgreSQL , we pioneered the agentic enterprise relational database by integrating advanced vector operations, machine learning inference, and foundation model integrations directly within a 100% PostgreSQL-compatible engine. It protects your data through deep Google Cloud security integrations — replacing static passwords with IAM authentication, isolating traffic via VPC Service Controls, and providing customer-managed encryption and auditing. This functionality, combined with the scalability now provided by our agentic architecture for agents, makes AlloyDB the premier enterprise-grade agentic PostgreSQL offering.

In today’s agentic era, we’re swiftly moving from single copilot agent interactions to networks of millions of agents collaborating simultaneously. When these agents query and operate all at once, sudden traffic spikes can overwhelm your core databases, competing with the systems that run your business.
