You want to run Kubernetes in a sustainable and affordable way? Then
|
|
this Kubernetes hosting is for you: Built specifically on low power
|
|
components, your Kubernetes cluster is not only friendly to your
|
|
wallet, but even more to the environment.

node that you add to your cluster contributes additional CPU, RAM and

persistent storage.

## Hosted Kubernetes Clusters by ungleich
|
|
|
|
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:
|
|
|
|
### 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.
|
|
|
|
## Standard building blocks
|
|
|
|
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
|
|
|
|
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.
|
|
|
|
## The ungleich kubernetes cluster
|
|
|
|
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](https://ceph.com/) 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.
|
|
|
|
|
|
## Pricing
|
|
|
|
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.

## Tech Details
|
|
|
|
### The ungleich k8s node
|
|
|
|
* CPU: AMD Ryzen 5 5600G
|
|
* RAM: 64 GB DDR4-3200
|
|
* OS SSD: M2, 128 GB or more
|
|
* Data SSD: SATA, 1 TB, usually ca. 500 MB read/write (work load dependent)
|
|
* Connectivity: 1 Gbit/s
|
|
* OS: Alpine Linux
|
|
* Networking: IPv6 only
|
|
|
|
### The ungleich k8s 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 by default
|
|
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.
