## News from the Matrix Home Server department
|
||||
|
||||
Here at ungleich we always have a look around, which Matrix home
|
||||
server to use. Obviously, you all know about
|
||||
[synapse](https://github.com/matrix-org/synapse), the reference
|
||||
server.
|
||||
Some of you might also know about
|
||||
[dendrite](https://github.com/matrix-org/dendrite), an experimental,
|
||||
maybe at some point in the future replacement of synapse.
|
||||
|
||||
But did you know about [conduit](https://conduit.rs/), a tiny Matrix
|
||||
homeserver written in Rust? Well, now you do.
|
||||
|
||||
## Next generation Matrix Home Server?
|
||||
|
||||
At ungleich we like to see what is coming next and conduit certainly
|
||||
has the potential to become an interesting, production grade
|
||||
homeserver. At the moment there are some
|
||||
[issues open for the 1.0
|
||||
milestone](https://gitlab.com/famedly/conduit/-/milestones/3#tab-issues),
|
||||
however conduit is actually already quite usable.
|
||||
|
||||
How stable you ask? Well, ...
|
||||
|
||||
## Phasing in public beta server at ungleich
|
||||
|
||||
To give you a preview, we have setup an **IPv6 only** instance of
|
||||
conduit at [conduit.ungleich.ch](https://conduit.ungleich.ch).
|
||||
|
||||
This server is open for public use, anyone (well, anyone with
|
||||
IPv6...) can register. However note: **this is only a test
|
||||
instance**. We might at any point in the future delete, replace or
|
||||
reset it. It is not backed and not a production service. It's main
|
||||
intent is to allow you to easily test out Conduit.
|
||||
|
||||
If you are looking for a production grade homeserver for yourself,
|
||||
have a look at our [hosted Matrix
|
||||
offerings](https://ungleich.ch/u/products/hosted-matrix-chat/).
|
||||
|
||||
That said - give it a shot. We think Conduit is a promising
|
||||
homeserver, especially given its focus on low resource usage.
|
||||
|
||||
## ... why IPv6 only?
|
||||
|
||||
There are several reason for it:
|
||||
|
||||
* IPv6 only is much easier to setup than IPv6+IPv4
|
||||
* This is a public beta service for which we try to keep the effort
|
||||
low
|
||||
* It's good test for us to see if conduit works in our IPv6 only
|
||||
networks
|
||||
* Global IPv6 traffic is nearing 50% and [many countries already
|
||||
exceed 50%](https://stats.labs.apnic.net/ipv6)
|
||||
|
||||
If you cannot access the conduit server because you don't have IPv6,
|
||||
you can always get IPv6 via [the IPv6VPN](/u/products/ipv6-vpn/).
|
||||
|
||||
## Follow up or questions
|
||||
|
||||
You can join the discussion either on the conduit server or you can
|
||||
also join our chat on https://chat.with.ungleich.ch (IPv6+IPv4 Synapse
|
||||
based Matrix server).
|
||||
|
||||

|
||||

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.

||||
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.
