Service certificate – STACKIT SQLSERVER
Service Name
STACKIT SQLServer Flex
High level service description
The STACKIT SQLServer Flex Service deploys managed instances of the Microsoft SQLServer relational database management systemindependently (DBMS). The service can be provisioned by the customer in various sizes. During the ordering process, a choice can be made between the High Availability (HA) and the Standard (singlenode instances) flavour. HA flavours are suitable for resilient operations with low downtimes for use in production environments. It is not recommended to use the standard version in a production environment. The customer can meet increasing demand through in-place upgrades to larger instances (service plans). Automated backups ensure the recoverability of customer data. The storage space of the instance is not linked to the service plan, enabling the customer to set up a more precisely tailored database for their application.
Key Features
- Access to Microsoft SQLServer relational database instances.
- On-Demand Provisioning: Easy and fast provisioning of new service instances of different sizes.
- Management Dashboard: Different self-services such as user management are available.
- High availability: Possibility of using clusters for increased resilience and fail-safety.
- Backup: Automatic creation of backups – „Point in Time Recovery“.
- High-performance storage space: Different persistent storage performance classes can be selected. The customer can react to the performance requirements of the application.
- Updates of STACKIT SQLServer Flex Services are scheduled and performed automatically.
Service Plans
During the ordering process, the customer has the option to choose from different configurations of the STACKIT SQLServer Flex Services. These differ primarily in terms of performance or storage capacity.
Metric
- Billing per commenced hour per provisioned STACKIT SQLServer Flex Service instance.
- Storage space and backup costs are displayed and billed separately as part of the STACKIT SQLServer Flex Services. Billing per commencedhour per commenced gigabyte.
SLA Specifics
- To achieve the highest possible availability of the STACKIT SQLServer Flex Service (e.g., for use in productive environments), the use of HA setups is strongly recommended.
- When using SQLServer Flex Service as a single instance, the SQLServer Flex Service may become (temporarily) unavailable, especially during maintenance work (e.g., through updates) that STACKIT performs on the underlying platform as well as on the selected instance variants. Maintenance work is considered an excluded event within the meaning of section 2.4 of the STACKIT Cloud service description and is therefore not considered as downtime in the context of availability. The use of the SQLServer Flex Service as a single instance in productive environments is strongly discouraged.
Backup
| Backup Parameter | Expression |
| Recovery Point Objective (RPO) | 4h |
| Recovery Time Objective (RTO) | 4h |
| Retention Period (RP) | 30 days (Default) |
An RTO of 4 hours applies to storage capacities smaller than 500 GB. For storage capacities of 500 GB or more, an extension of the RTO of approx. 1 minute for each additional 10 GB or part thereof can be expected. If the customer changes the backup mode of STACKIT SQLServer Flex Service to a mode other than the pre-set “Complete” mode, this may result in adverse deviations from the agreed availability levels, as well from the RPO and RTO described above. In the event of a change made by the customer, the latter is not entitled to the service levels agreed by STACKIT.

- Monitoring of the available storage space as well as the performance KPIs and the adaptation of backup times fall within the responsibility of the Customer.
- Restoring backups of STACKIT SQLServer Flex instances is the responsibility of the customer.
