EDB POSTGRES AI · DISTRIBUTED HA
Built to never stop.
Transform Postgres® into a distributed, always-on platform. For businesses where downtime isn't an option, EDB Postgres AI (EDB PG AI) keeps your applications running globally through any condition.
EDB empowers the architects of the modern enterprise
Traditional HA was built to help you recover, not recover for you.
Today's enterprise databases are only built to survive failure. When a node goes down, your teams scramble across multiple tools to detect it, promote a standby, and reconfigure clients while your application waits. Every minute of downtime is lost revenue, damaged trust, and regulatory exposure.
How always-on Postgres works
-
1 — DEPLOY
Active-active clusters across regions
Configure through a unified control plane: graphical topology, point-and-click, no manual scripting.
-
2 — SYNCHRONIZE
Zero data loss
A node can fail. Your data doesn't. Every transaction lands in more than one region before it counts as done.
-
3 — RECOVER
Sub-second recovery
When a node or region goes offline, traffic reroutes to active nodes instantly. No standby promotion, no reconfiguration.
-
4 — RESOLVE
No manual cleanup
When two regions write at once, the system reconciles conflicts automatically so your source-of-truth database is current and correct.
-
5 — UPGRADE
No planned downtime
Rolling upgrades apply incrementally across nodes. Your cluster stays operational throughout, without maintenance windows.

EDB Sovereign Assurance Program
We don't just hand you infrastructure and wish you well.
We sell you the system. And then we ensure it runs. With included services blocks and a technical account manager, the EDB Sovereign Assurance program is a commitment to qualifying customers to provide the assistance you need for your sovereign deployment to be operational in weeks, not months.
Key capabilities
Where distributed HA lives in the platform.
EDB PG AI delivers distributed resilience at the data layer, so sovereignty is part of the architecture, not an afterthought. Active-active clustering, automatic recovery, and a unified control plane keep your applications always on, without the limits and complexity of traditional HA.
Distributed HA runs anywhere Postgres runs.
Run on-premises, hybrid, or across any cloud. Global clustering and granular data placement enforce regional sovereignty and help meet compliance requirements, without external control plane or vendor lock-in.

Frequently asked questions
Active-active replication lets multiple Postgres nodes accept reads and writes at the same time, across regions. Unlike traditional primary-standby setups, there's no single writer and no idle standby waiting to take over. If a node goes offline, traffic continues on the others with no promotion step and no downtime.
Yes. EDB PG AI supports up to 99.999% availability through active-active clustering across regions. Because every node is active, planned maintenance and major version upgrades roll out one node at a time while the cluster stays online, so you reach five nines without disruptive maintenance windows.
Data placement is controlled at the data layer. You define which regions data is stored and replicated to. For example, countries European data can stay on European nodes while remaining part of one unified database. Row-level and table-level filtering helps you meet GDPR and similar requirements without sacrificing performance or a single source of truth.
Active-active replications and features like quorum commit, a distributed consensus mechanism that validates every transaction across a majority of nodes before it is confirmed. This ensures strict data consistency across regions for mission-critical applications like banking and payments, eliminating post-transaction conflict resolution.
