# PostgreSQL

## Description

PostgreSQL is currently the leading open source RDBMS (Relational Database Management System), with a wide range of features and a large community supporting it.

cegedim.cloud provides fully managed PostgreSQL databases instances to let you build your applications without operating availability, security and resilience of PostgreSQL databases.

## Platform as a Service

PostgreSQL is deployed on-premise in cegedim.clou&#x64;**'**&#x73; data centers.

The same level of service as the Compute offer is guaranteed : deployment of instances, maintenance in operational condition, flexibility, security and monitoring are thus ensured by our experts.

Two types of PostgreSQL deployments are available :

* **Standalone Instance**
* **High availability :** two PostgreSQL instances with automatic fail-over for improved resiliency

Sizing can be configured according to your needs.
