# Service description
***
Our Managed Database service for PostgreSQL provides a secure, scalable, and maintenance-free environment for your applications. Each instance includes a pre-created database, supporting one database per instance, which is automatically provisioned at the time of creation. It's the ideal solution for teams looking to streamline operations and focus on development without managing infrastructure. [Learn more](https://glesys.com/services/dbaas)

### Technical specification
| **Customer self-service** | Yes. Managed in Glesys Cloud and available via API |
| ---------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Engine version(s)** | PostgreSQL version 18 |
| **Default database** | Yes. One default database is created when the instance is provisioned. |
| **Multiple databases** | Yes. You can create multiple databases within an instance. |
| **Database users and permissions** | Yes. You can create and remove database users. Supported permission levels are Full access and Read-only. |
| **Root user privileges** | No |

| **Availability and access** | By default, all traffic is blocked. As a user, you add IP addresses that are allowed to connect to the database. |
| **Disk full failure prevention** | Database instances automatically switch to read-only mode when the disk is almost full, with 3 GiB remaining. Preventing writes stops the disk from continuing to fill and keeps the instances available for reads. During the read-only mode, you can take measures to free more disk space. |

### Predefined plans
Glesys offers a wide spectrum of plans to serve use cases that range in size from personal blogs to large datasets and high-transaction applications.
Please note that there is currently no feature in the UI to switch plans. However, users can utilize a SQL dump provided by us and restore it to a new instance with the desired resources.

### Monitoring
Monitoring is available via a Prometheus-compatible endpoint; however, customers must set up their own solution to store historical metrics. Access to systemd logs and the slow query log is not available.
### Maintenance
You will be assigned a regular and recurring day and time each week for maintenance. Occasionally, Glesys performs maintenance tasks on the managed PostgreSQL database. These tasks typically include updating the underlying infrastructure of the database, such as patching the operating system, updating necessary libraries, or upgrading PostgreSQL itself. Glesys manages these maintenance tasks automatically. During maintenance, the database may experience a brief period of downtime, which can last up to 10 minutes.
