The ungleich Low Power Kubernetes Hosting offer

Our Kubernetes Hosting might be the world's most environment friendly Kubernetes hosting out there. Not only are all components carefully chosen to use as little energy as possible, but additionally the electricity is coming from 100% renewebale energy sources.

Environment friendly, for real

Other providers are dealing with Carbon Certificates, offsetting their energy and claiming to be green. None of that makes sense to us, as the emissions are produced nonetheless, fossil fuels are used or nuclear energy contributes to running your Kubernetes cluster elsewhere.

Here at ungleich we start from the beginning and continue to improve our energy usage every day. Not only are we using a 100% renewable energy (locally produced!), but we also research specific hardware to optimise the energy usage required by Kubernetes clusters.

#

Each Kubernetes cluster consists of 3 or more k8s nodes. While you can grow it with adding individual nodes, we recommend to grow it in numbers of 3. The reason for this is the underlying storage technology Ceph that saves each of your data blocks 3 times.

Failure resistent

As your workload is running on any of the k8s nodes, maintenance work and failovers can be executed without interrupting the services (assuming your workload is deployed accordingly).

Storage support included

Using a built-in dedicated Ceph cluster we provide you with persistent storage that can be accessed using standard Kubernetes PVCs.

As every k8s node contains a dedicated SSD, by adding new nodes, your storage cluster automatically grows as well.

As the Ceph cluster stores every object 3 times, the 1 TB SSD of each node contributes about 300GiB usable storage.

Simple Pricing

Our pricing is very simple: Each pack of 3 node nodes is 225 CHF/month. This includes rental of the hardware, network traffic, electricity and maintenance of the kubernetes cluster.

You don't have to worry about additional storage, network fees or other hidden costs.

Need more power?

When you start with our low power Kubernetes hosting and at some point in the future you realise that your applications need more resources, you can even combine the low power Kubernetes hosting with the High Performance Kubernetes Hosting.

The ungleich Kubernetes cluster

The Kubernetes control plane access is available via IPv6 and IPv4. All pods are running in a dedicated /64 IPv6 network. Service IPs are IPv6 only and are located in a second /64 IPv6 network.

The cluster does not support type=LoadBalancer, because it is not necessary in IPv6 only environments. ClusterIPs are already world reachable.

IPv4 reachablity can be configured in two ways:

  • Via our IPv4-to-IPv6 proxy (http, https based)
  • Via a dedicated IPv4 address

The current stack uses Calico as the CNI.
