Features
Better price-performance
AlloyDB is more than 4x faster for transactional workloads and provides up to 2x better price-performance compared to self-managed PostgreSQL.* It's suitable for the most demanding enterprise workloads, including those that require high transaction throughput, large data sizes, or multiple read replicas. Read connections scale horizontally, backed by low lag, scale-out, autoscaling read replica pools, and support cross-region replicas. Committed use discounts offer additional savings for one to three year commitments.
Fully featured vector database
AlloyDB AI can help you build a wide range of AI agents and apps. It uses the Google ScaNN index, the technology that powers services like Google Search and YouTube, to deliver up to 6 times faster vector queries and up to 10x faster filtered vector search queries than the HNSW index in standard PostgreSQL, scaling to over 10 billion vectors.* It helps you generate vector embeddings from within your database, query across SQL and vector data, integrate with orchestration frameworks, and access AI models on Gemini Enterprise Agent Platform and other platforms.
Runs anywhere
AlloyDB Omni is a downloadable edition of AlloyDB, designed to run anywhere—in your data center, on your laptop, at the edge, and in any cloud. It’s powered by the same engine that underlies the cloud-based AlloyDB service and provides the same functionality. AlloyDB Omni is a fraction of the cost of legacy databases, so it’s an attractive way to modernize to an enterprise-grade version of PostgreSQL with support from a Tier 1 vendor.
AI-driven development and operations
Simplify all aspects of the database journey with AI-powered assistance, helping your teams focus on what matters most. AlloyDB Studio offers a query editor where you can use Gemini to write SQL and analyze your data using natural language prompts. Database Center provides a comprehensive view of your database fleet with intelligent performance and security recommendations, while agentic database observability enables an easy-to-use chat interface for troubleshooting and optimization of your databases.
Real-time business insights
Thanks to its built-in columnar engine, AlloyDB is up to 100x faster than standard PostgreSQL for analytical queries*, with zero impact on operational performance when running business intelligence, reporting, and hybrid transactional and analytical workloads (HTAP). You can also access and write data to Lakehouse Apache Iceberg and BigQuery tables, and call AI models in Gemini Enterprise Agent Platform directly within a query or transaction.
Fully managed database service
AlloyDB is a fully managed database service with cloud-scale architecture and industry-leading performance, availability, and scale. It automates administrative tasks such as backups, replication, patching, and capacity management, and uses adaptive algorithms and machine learning for PostgreSQL vacuum management, storage management, memory management, data tiering, and analytics acceleration, so you can focus on building your applications.
PostgreSQL compatibility
PostgreSQL has emerged in recent years as a leading alternative to legacy, proprietary databases because of its rich functionality, ecosystem extensions, and enterprise readiness. AlloyDB is fully compatible with PostgreSQL, providing flexibility and true portability for your workloads. It closely tracks PostgreSQL releases, offering safe, easy upgrades and extended support if you need more time to upgrade. It’s easy to migrate existing workloads and bring your existing PostgreSQL skills over.
High availability
AlloyDB offers a 99.99% uptime SLA, inclusive of maintenance. It automatically detects and recovers from most database failures within 60 seconds, independent of database size and load. The architecture supports non-disruptive instance resizing and database maintenance, with planned operations incurring less than 1 second of application downtime. Read pools are updated with zero downtime.
Scalability
Scale AlloyDB instances up and down and deploy up to 20 read replicas in an autoscaling read pool for read scalability. You can create secondary clusters in different regions for disaster recovery, have them continuously replicated from the primary region, and use an automated failover process in case of an outage. Regional replicas deliver more than 25x lower replication lag than standard PostgreSQL for high throughput transactional workloads. They also improve read performance by bringing data closer to your users.
Secure access and connectivity
AlloyDB encrypts data in transit and at rest. It supports private connectivity with Virtual Private Cloud (VPC) for secure connectivity to your applications, and allows you to access your database instances via private IP without going through the internet or using external IP addresses. You can manage your own encryption keys to encrypt data at rest for your database and your backups, and you can choose between Identity and Access Management (IAM) and PostgreSQL user roles for database authentication.
Continuous backup and recovery
Protect your business from data loss with point-in-time recovery to any point within your defined retention window. Restore the database to a specific date and time for development, testing, and auditing purposes, or recover your production database from user or application errors. You no longer need expensive hardware and software solutions to achieve enterprise-level data protection.
Conversational analytics
Conversational analytics for AlloyDB lets you create data agents in the AlloyDB console, an IDE, or CLI, and chat with them in natural language about your database data. For example, you can use conversational analytics to manage database operations, ask questions about the business data in your AlloyDB database, and support your software development lifecycle.
With QueryData, you can translate natural language into database queries with near-100% accuracy, allowing you to build agentic experiences across AlloyDB.
Data Agent Kit
The Data Agent Kit streamlines your workflows by bundling secure Model Context Protocol (MCP) tools, native IDE plugins, and pre-codified data engineering, data science, and data app developer skills into a single, open-source package. With support across AlloyDB, BigQuery, Cloud SQL for MySQL, Cloud SQL for PostgreSQL, Dataflow, Spanner, and more., developers can now focus on intent-driven development across the entire data estate.
Lakehouse federation and sync
Access live data from Lakehouse for Apache Iceberg and BigQuery directly from PostgreSQL queries with AlloyDB's lakehouse federation. Serve data back to AlloyDB with single-click reverse ETL to provide operational insights with low latency and high concurrency, and use Datastream to complete the data loop by writing data back to Iceberg and BigQuery tables. Leverage Knowledge Catalog for data governance across the lakehouse and AlloyDB for easy data discoverability.
Easy migrations
No matter where your source database is located—whether on-premises, on Compute Engine, or in other clouds—Database Migration Service (DMS) can migrate it to AlloyDB securely and with minimal downtime. DMS leverages native PostgreSQL replication capabilities and automated schema and code conversion, as necessary, to maximize the reliability of your migration. Gemini adds AI-powered assistance for heterogeneous database migrations, helping you review and convert database-resident code and offering full explainability. For an assessment of your migration needs, try the Database Modernization Program.
Customer-friendly pricing
Eliminate your dependency on high-cost, proprietary databases, and take advantage of transparent and predictable pricing with no proprietary licensing or opaque I/O charges. Storage is automatically managed and you're only charged for what you use, with no additional storage costs for read replicas. An ultra-fast, automatically provisioned cache allows you to maximize the price-performance ratio. Committed use discounts offer additional savings for one to three year commitments. And AlloyDB Omni offers another simple and affordable deployment option.
