APPUiO Managed - Exoscale SKS

APPUiO Managed Kubernetes Services with Exoscale Scalable Kubernetes Service (SKS) is our product to provide services for the managed Kubernetes offering of Exoscale.

Use Cases

Full Production Readiness

Managed cloud services are engineered for production. Leveraging these services is the recommended path into production.

Step in to the Cloud

Managed cloud services are perfect to start using the cloud. If the cloud is already used, managed cloud services are the perfect way to use Kubernetes.


Using Kubernetes from Hyperscaler clouds allows for full scalability. With Hyperscaler-managed Kubernetes, you can get rid of infrastructure "pets" that need special attention. See The History of Pets vs Cattle and How to Use the Analogy Properly for a good read.


Hyperscaler clouds not only offer Kubernetes, but a large amount of other services. By using the Kubernetes offering of a Hyperscaler cloud, all the other available services are just waiting to be used. All our APPUiO Managed clusters have the Application Catalog on board.

Costs saving

Usually big clouds are not necessarily cheaper out of the box. By using the possibilities the cloud offers with integrated Cluster autoscaling or other optimization tricks like "Spot" instances a huge cost saving can be achieved.

VSHN Supported Features and Configuration

Supported by default

These features and configurations are available out-of-the box and installed and configured by default.

Feature / Configuration Description

Cluster Maintenance

Kubernetes control-plane and node updates are applied continuously when they’re available. See also Version and Upgrade Policy.

Persistent Storage with CSI

Storage is provided by the native cloud storage offering using officially support CSI integrations.

Cluster Backup

A full backup of the etcd database is made every 4 hours. This includes a dump of all objects in JSON format, this way single objects can be restored on request. The backup data is encrypted before it is stored in an object storage backend, usually on the same cloud as the cluster is running. K8up is used as the backup operator, using Restic as backup backend.

Persistent storage volumes are not automatically backed up. The user of persistent volumes is obliged to take care of this. For that purpose, K8up is available on the cluster to help with that task. We’re also happy to help, just let us know.

Cluster limits

We’re following the recommendations of upstream Kubernetes. See Limits for more details.

Supported on request

These features or configuration adjustments must be specifically requested and some restrictions apply. Activation and configuration of these features imply additional engineering costs and can cause additional recurring engineering costs for operating them.

Feature / Configuration Description

Cluster Autoscaling

Cluster autoscaling configuration is fully supported, depending on the possibilities of the cloud service.

Version and Upgrade Policy

Supported are only the Kubernetes versions of Exoscale: SKS lifecycle management. Installations must be upgraded to the next release within three months after a new release is available.
