GleSYS manages the underlying infrastructure, provisioning, automated backups and platform maintenance, while customers retain responsibility for database administration, SQL queries, performance optimisation and data recovery. Instances are provisioned automatically at creation and are suitable for development, testing and production workloads.

Managed through our [control panel](https://cloud.glesys.com/signup) 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 | | **Disk IOPS** | 12,000 | | **PostgreSQL extensions** | [See list of supported extensions](/products/database/details/postgresql/supported-postgresql-extensions.md) | | **Database replication feature** | No | | **Automated failover feature** | No | | **Change engine version support** | No | | **Encryption at Rest** | No – database storage is not encrypted at the database service layer. | | **Encryption in Transit** | Yes, TLS | | **Availability and access** | Incoming database traffic is blocked by default. Customers explicitly allow the IP addresses or networks that require access to the database instance. | | **Disk capacity protection** | To protect the database from running out of disk space, the instance automatically enters read-only mode when available disk capacity reaches the configured safety threshold. Approximately 3 GiB is reserved to allow maintenance and recovery operations. | | **Processing of personal data** | Storage, transfer | ### Automated backup | **Backup frequency** | Daily | | --------------------------------- | ------- | | **Retention** | 14 days | | **Remote backups** | Yes | | **Point-in-time recovery (PITR)** | No | | **Custom backup schedule** | No | Automated backups are managed by Glesys. Customers are responsible for verifying that backups meet their recovery requirements and for performing database recovery. Glesys provides the required SQL dump where applicable. ### Predefined plans Database instances are created using predefined resource plans. Changing an existing instance to another plan is currently not supported in the control panel. To move to a different resource configuration, create a new instance with the desired plan and migrate the database using an SQL dump. | **vCPUs** | **Memory** | **Storage** | **Max. Connections** | | --------- | ----------- | ----------- | -------------------- | | **1** | 4 GiB RAM | 25 GiB | 100 | | **1** | 4 GiB RAM | 50 GiB | 100 | | **2** | 8 GiB RAM | 50 GiB | 200 | | **2** | 8 GiB RAM | 100 GiB | 200 | | **4** | 16 GiB RAM | 50 GiB | 400 | | **4** | 16 GiB RAM | 100 GiB | 400 | | **4** | 32 GiB RAM | 150 GiB | 800 | | **4** | 32 GiB RAM | 300 GiB | 800 | | **8** | 64 GiB RAM | 150 GiB | 1,600 | | **8** | 64 GiB RAM | 300 GiB | 1,600 | | **8** | 128 GiB RAM | 150 GiB | 3,200 | | **8** | 128 GiB RAM | 300 GiB | 3,200 | ### Monitoring Database metrics are available through a Prometheus-compatible endpoint. Customers are responsible for connecting the endpoint to their monitoring platform and for storing historical metrics. Access to systemd logs and PostgreSQL slow-query logs is currently not provided through the service. ### Maintenance Each database instance is assigned a recurring weekly maintenance window. Glesys may use this window to perform maintenance on the managed platform, including operating system updates, security patches, dependency updates and PostgreSQL maintenance. Maintenance is performed automatically by Glesys and may result in temporary database unavailability. Planned maintenance may cause downtime of up to 10 minutes. ### Responsibilities | **Underlying infrastructure** | Glesys | | ----------------------------------------------- | -------- | | **Instance provisioning** | Glesys | | **Platform maintenance and patching** | Glesys | | **Automated backups** | Glesys | | **Database administration** | Customer | | **SQL troubleshooting** | Customer | | **Query and database performance optimisation** | Customer | | **Historical metrics storage** | Customer | | **Backup verification** | Customer | | **Database recovery** | Customer |
