SysEleven DBaaS Concepts

Service description

Last updated: November 2025

Summary

SysEleven Database as a Service (DBaaS) is a fully managed, scalable database service on the SysEleven Cloud. It simplifies provisioning, operations, and scaling of databases and enables workloads without running own infrastructure or platform layers.

Scope & Goals

  • Provisioning of database systems for development, test, and production
  • Operations & lifecycle: patches, upgrades, monitoring, backup/restore
  • Scaling: vertical (CPU/RAM) and horizontal (instance count/cluster) as needed
  • Security: encryption, audit logs, role-based access
  • Self-service: Web UI, API, and Terraform provider

Supported Database Engines

Currently, SysEleven DBaaS supports the following database engine: - PostgreSQL

Regions and Availability Zones

SysEleven DBaaS is available in regions DUS2&HAM1.

Service Features

Automatic backups

  • Configurable backup windows and retention. Point-in-Time Recovery (PITR) for PostgreSQL.

Data protection and security

  • Secure and certified data centers. TLS encryption in transit.

Flexibility and scalability

  • Adjustable resources (CPU, RAM, storage). Clusters with up to five instances for PostgreSQL.

High availability (HA)

  • Multiple instances with automatic failover.

  • Single-instance deployments are possible but not recommended for production. Single-instances have limited availability; incidents may lead to longer outages because no automatic failover exists and a new VM may need to be provisioned first. See Service Levels.

Infrastructure as Code with Terraform

  • Supported via Terraform provider.

Fast provisioning

  • On-demand provisioning.

Transparent billing

Architecture & Provisioning

  • Topologies: single-instance or HA cluster (1 primary + n replicas)

  • Provisioning: Web UI, API, or Terraform; status events/webhooks for progress and completion

  • “READY” definition: endpoint reachable, primary writable, replication active (stable lag), monitoring & backups configured

Network & Access

  • Access paths: private networking and internet-based connections

  • Security: TLS enforced (e.g., TLS ≥ 1.2), optional IP allowlists/firewall rules

  • Identity & rights: IAM-protected API access; database access via users/roles and passwords/secrets

Security & Compliance

  • Operation in secure and certified German data centers. Data sovereignty remains with the customer.

  • Encryption: data in transit (TLS) and at rest. Block and object storage are encrypted in the new NCS regions.

  • Audit & traceability: event/access logging; audit logs available (scope, retention, export per technical documentation).

Service Level (SLA/SLO)

Availability

  • HA setups (multiple instances): 99.9% availability

  • Single-instance: best-effort operation; not recommended for production. Limited availability and potentially longer outages due to missing automatic failover and possible VM rebuilds.

Backup & restore

  • PITR supported

  • Default retention: 7 days; configurable within policy and storage budget

Billing & Price Units

  • Instances: billed per started hour per provisioned instance

  • Storage & backups: billed separately per GB-hour (provisioned storage, plus backup storage where applicable)

Monitoring & Observability

  • Platform monitoring (SysEleven): e.g., availability, replication status, system health
  • Customer monitoring: capacity and performance metrics (CPU/RAM/IO, disk usage). Query tuning and capacity planning are customer responsibilities.

Operations & Maintenance

  • Maintenance windows: customer-selectable; platform maintenance is announced

  • Security/emergency maintenance: may be executed at short notice and without prior announcement for security or stability reasons

  • Maintenance exclusions: planned and emergency maintenance do not count as downtime for availability calculations

Responsibilities (RACI – excerpt)

  • SysEleven: platform operations, platform security, upgrades, HA mechanisms & failover, base monitoring, backup infrastructure

  • Customer: database updates, schema & data, users/roles, application tuning, capacity/performance monitoring, backup policy adjustments, triggering/validating restores

Backups & Restore

  • Backups: self-service per configuration; defined windows and retention

  • Restore: self-service restore (e.g., to a new point in time/instance)

Limits & Exclusions (excerpt)

  • Single-instances: not recommended for production; no HA commitment

  • Size dependency: restore times scale with data volume and selected storage profile

  • Third-party tools: usage is possible; SysEleven support covers the platform only, not third-party tools (e.g., pgAdmin)

Roadmap & Changes

DBaaS is continuously improved with a focus on security, performance, and reliability.
The current roadmap is available at:

https://documentation.syseleven.de/en/products/syseleven-dbaas/roadmap/

Support & Availability

  • Support plan: “Self-Service” (product and platform support per plan)

  • Service availability: 24/7

  • Incident handling: best-effort; escalation paths per support plan
