Service Certificate – STACKIT Compute Engine
Service Name
STACKIT Compute Engine
High level service description
STACKIT Compute Engine (“Compute Engine”) provides Virtual Machines (“VM”) consisting of a combination of processor (“vCPU”) and memory (“RAM”). The customer can choose the optimum VM for its application from a wide range of prefabricated variants (“Flavors”). The provision, management and deletion of the VM is carried out by the customer itself. Either the STACKIT Portal or the STACKIT API can be used for this purpose.
Key Features
- Creation, usage and deletion of VMs according to individual requirements.
- Use of the service in self-service using a graphical interface in the STACKIT Portal and using the STACKIT API.
- One or more Availability Zones (AZ) for provisioning VMs in different availability classes.
- Each Availability Zone is separated in power supply, cooling and local network connectivity from the other Availability Zones.
- Several Availability Zones can be located in the same building.
Service Plans
The service plans are generally provided with (Table 1) and without (Table 2) CPU overprovisioning. The following Flavors are currently available. The version is marked accordingly in the flavor (e.g. “c1a“). The hardware on which the VM is based (e.g. processor type) is specified and described in the additional documentation (STACKIT knowledgebase) and can be viewed there by the customer.
The current list can be taken from the STACKIT Portal or viewed via STACKIT API.

Local Disk
- The local disk refers to the local disk space that is available to the respective VM for the operating system.
- The local disk is not persistent in the case of individual system failures. It is therefore only suitable for temporary or replicated data.
- If no local disk is available, the customer must use a disk from the separate Block Storage to use the Compute Engine (Block Storage represents a separately obtainable STACKIT Cloud Service, see Service Level Agreement – STACKIT Block Storage, “Block Storage”).
Metric
- Billing per VM per hour or part thereof.
- Calculated Period: Creation of the VM until deletion of the VM minus any shelving periods. Shelving corresponds to stopping the VM with cancellation of resource reservation.
- For other resources used by the customer in conjunction with a VM, such as Block Storage and Backup Storage, a separate charge is made according to the conditions specified in the respective Service Level Agreement.
SLA Specifics
- For all VMs which are provided in a single availability zone (single VMs without a highly available system group with several VMs), an availability of 99.5% in the calendar month average is agreed.
- For VMs deployed in a Metro Availability Zone, an availability of 99.8% on a calendar month average is agreed.
- For all system groups, i.e. those which are provided by means of two VMs in two different Single Availability Zones in the same region, an availability of at least one VM of 99.9% in the calendar month average is agreed upon.
- VMs that are waiting for access to their disk due to a Block Storage failure still count as available.
- The availability data refers to the availability of the VMs that are in operation. It does not include configuration or customer-related properties for non-availability (e.g. a shutdown of the VM).
Backup
- Backup und Wiederherstellung der Compute Engine obliegen dem Kunden und sind nicht im Service enthalten. Dies bezieht sich insbesondere auf
- The defintion (properties configured by the customer) of the VM itself.
- The data of the possible local disk.
- The data of a disk when using the Block Storage.
Additional Terms
- The customer may use VMs of the Compute Engine to install and run software licensed separately by customer.
- When creating VMs, public operating system images can be used. An overview of usable operating system images provided by SIT is available in the STACKIT Portal and/or the documentation. SIT reserves the right to expand or reduce the portfolio of operating system images provided by SIT for the creation of new VMs at any time. Existing instances of VMs are not affected. With the provision of the operating system images, SIT does not provide any licenses for or on behalf of the customers. By using one of the public operating system images, the customer accepts the license terms of the respective manufacturer applicable at the time of the conclusion of the contract; the license terms for each manufacturer of operating system images provided by SIT are listed below separately for each manufacturer (“Third Party Terms”). With regard to the relevant Third Party Terms, an agreement is concluded between the customer and the respective manufacturer.
- The correct licensing of the operating system images or software used on the VMs is the sole responsibility of the customer, unless SIT has expressly assumed licensing for the customer as an object of the service. If SIT takes over a licensing as part of the contract between SIT and the customer, this will be pointed out separately in the respective Service Level Agreement.
- An operating system image selected by the customer does not become an object of performance of the contract between SIT and the customer. Accordingly, SIT does not assume any warranty for the operating system image selected by the customer and does not make any availability promises in this respect.
- Management of the operating system and other software on the VMs is the sole responsibility of the customer. This includes, but is not limited to, installation, operation, the import of updates and patches, maintenance, backup and support.
- The customer is responsible for the security of its virtual machine.
- The Third Party Terms listed below apply between the customer and the operating system manufacturer, depending on the operating system image selected by the customer when creating a VM:

- Debian: https://www.debian.org/social_contract#guidelines
