Overview

PostgreSQL power. Infinite possibilities.

Trust Azure HorizonDB with your mission-critical apps at any scale and turn your data from asset to advantage.
  • Modern apps need fast, scalable infrastructure. Azure HorizonDB delivers up to three times faster performance than open-source Postgres. Auto-scaling storage and scale-out compute adapt to changing workloads so you can build what’s next with confidence.

  • Organizations need robust security and continuity to protect operations and maintain trust. Azure HorizonDB is enterprise-ready from day one for mission-critical workloads, with built-in identity, secure connectivity, encryption, and default multi-zone replication for sensitive cloud data.
  • Developers face pressure to deliver intelligent, scalable apps fast—but infrastructure setup, data access, and AI integration remain complex. Azure HorizonDB embeds AI-native capabilities directly in the database, enabling teams to move from idea to impact without compromise.
Features

PostgreSQL optimized for what comes next

Dynamic performance

Handle workloads from kilobytes to 128 TB with auto-scaling storage, and deliver up to three times the transactional performance of open source Postgres.

Rapid read scale-out

Scale to 3,072 vCores across primary and replica nodes.

Data protection

Detect, track, and remediate threats in real time with Microsoft Defender protection and simplify identity and access management with Microsoft Entra ID integration.

Advanced filtered vector search

Unlock high-speed AI applications and lower costs by merging DiskANN vector search and filtering into a single operation.

Convenient AI model management

Streamline development with an in-database service that provides a curated set of pre-provisioned AI models.

Semantic ranker

Re-rank vector search results with semantic ranking models to improve query accuracy for Postgres AI agents and apps.

Mirroring in Microsoft Fabric

Avoid complex extract, transform, and load (ETL) and replicate your data in near-real time to Microsoft Fabric to unlock new business intelligence and more.

Visual Studio Code integration

Simplify database management and development workflows while minimizing task-switching, all within your favorite code editor using the PostgreSQL extension for VS Code.

GitHub Copilot

Streamline workflows with real-time code suggestions and routine task automation using context-aware GitHub Copilot in the PostgreSQL extension for Visual Studio Code.

FAQ

Frequently asked questions

  • Azure HorizonDB availability is currently limited. See our announcement blog for the latest availability.
  • Customers are invited to apply for early preview access to get hands-on experience with this new service. Participation is limited and subject to availability.
  • HorizonDB is a fully-managed, cloud-native PostgreSQL database service  architected to deliver performance, resilience, and security for high-throughput, data-intensive applications. Currently in limited preview, Azure HorizonDB gives you faster provisioning times and lower write latency.  It can quickly scale more compute and storage, with more scale-out capacity for heavy read operations. By contrast, Azure Database for PostgreSQL is our database service for running open source PostgreSQL on Azure, delivering a fully managed experience for traditional PostgreSQL deployments.
  • Microsoft has approximately 20 employees who actively contribute to the PostgreSQL open-source community in a variety of ways, including:
    • Authoring code and submitting new features or improvements
    • Reviewing commits and ensuring code quality
    • Serving as committers (also known as maintainers in other open-source projects) 
    • Holding leadership roles, such as positions on the PostgreSQL core team
    • Supporting community education and advocacy, helping users learn and adopt PostgreSQL

    In fact, Microsoft is one of the top upstream code contributors to the PostgreSQL open-source project. Learn more about why we contribute to Postgres open source in our annual “What’s new with Postgres at Microsoft” blog post.
