[Yandex Cloud documentation](../index.md) > Yandex Managed Service for Sharded PostgreSQL > Managed Service for Sharded PostgreSQL # Yandex Managed Service for Sharded PostgreSQL With Managed Service for Sharded PostgreSQL, you can deploy sharded PostgreSQL (SPQR) clusters in the Yandex Cloud infrastructure. SPQR (Stateless Postgres Query Router) is a system for horizontal scaling of PostgreSQL via sharding, based on Yandex Open Source technologies. The Yandex Cloud infrastructure is protected pursuant to the following standards: This service is subject to a service level agreement. The service level is set out in the document titled Yandex Managed Databases Service Level. # Yandex Managed Service for Sharded PostgreSQL - [Getting started](quickstart.md) ## Step-by-step guides -
