Azure Database for PostgreSQL documentation
Azure Database for PostgreSQL is a relational database service based on the open-source Postgres database engine. It's a fully managed database-as-a-service offering that can handle mission-critical workloads with predictable performance, security, high availability, and dynamic scalability. It's available in two deployment options, as a single server and as a Hyperscale (Citus) cluster (preview). The Hyperscale (Citus) option horizontally scales queries across multiple machines using sharding, and serves applications that require greater scale and performance.
