Your Kubernetes cluster can start from 3 nodes and grow to any size. Every node that you add to your cluster contributes additional CPU, RAM and persistent storage.
The Kubernetes cluster and the operating system are maintained by ungleich. You can deploy your applications worry free.
Your Kubernetes cluster is running on dedicated hardware. No interruption, no rescheduling, no peer pressure. All resources are 100% usable by you.
The kubernetes cluster is based on AMD Ryzen CPUs to provide 12 threads per node and 64GB RAM. The operating system is stored on an SSD and your data is stored on a second SSD.
Each Kubernetes node has been tested to consume less than 100W at maximum performance. While our data center is using 100% renewable energy, we try to even make an extra effort to reduce impact on the environment.
The Kubernetes cluster is ready for the IPv6 world: all nodes are running on an IPv6-only network. For IPv4 reachability we offer you dedicated mapped IPv4 addresses.
While you might be aware of other managed Kubernetes clusters, here at ungleich we have quite a different offering. Let's start with the obvious ones that you are unlikely to experience anywhere else:
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.
Other providers offer you a complex system of building blocks: this CPU, that memory, different storage classes, bandwidth consumption and so on and so on. You easily lose the track of what you wanted to do in the first place: to run your workload.
Here at ungleich we offer you exactly 1 building block to build your kubernetes clusters: The ungleich k8s node.
The ungleich k8s node is an AMD based, 12 thread computer with 64 GB of main memory and two SSDs. The first SSDs is used for storing the operating system and the second SSD is used to store your data.
The second SSD has a capacity of 1TB.
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.
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).
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.
Our pricing is very simple: Per K8S node we charge 300 CHF/month. This includes rental of the hardware, network traffic, electricity and maintenance of the kubernetes cluster.
This might not be the cheapest kubernetes you can build, but it is probably the world's most energy aware and most modern Kubernetes cluster out there.
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 by default world reachable.
IPv4 reachablity can be configured in two ways:
The current stack uses Calico as the CNI.
