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.
|
|
|
|
Each Kubernetes node has been tested to consume less than 20W 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 low power Kubernetes hosting not only is very environment
|
|
friendly, but also very friendly to the budget. By using significantly
|
|
less resources, you contribute to saving the environment as well as
|
|
spending money on resources you don't need.
|
|
|
|
When starting small, you always have the possibility to grow your
|
|
cluster in the future, reacting to the actual needs.

feature3_text:
|
|
Your Kubernetes cluster is running on dedicated hardware. No
|
|
interruption, no rescheduling, no peer pressure. All resources are
|
|
completely usable by you.
|
|
|
|
All our Kubernetes cluster are fully ready for the IPv6 world:
|
|
all nodes are running on an IPv6-only network. For IPv4 reachability
|
|
we offer you dedicated mapped IPv4 addresses.

## 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](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.
|
|
|
|
|
|
## 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](../kubernetes-hosting-high-performance).

## Tech Details
|
|
|
|
### The Low Power kubernetes node
|
|
|
|
* CPU: [Intel Pentium CPU J4205](https://www.intel.com/content/www/us/en/products/sku/95591/intel-pentium-processor-j4205-2m-cache-up-to-2-60-ghz/specifications.html)
|
|
* RAM: 8 GB DDR3
|
|
* OS SSD: 128 GB
|
|
* Data SSD: USB-C, 1 TB
|
|
* Connectivity: 1 Gbit/s
|
|
* OS: Alpine Linux
|
|
* Networking: IPv6 only
|
|
|
|
### 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.
