Let's start with the +obvious ones that you are unlikely to experience anywhere else: -## Development flow +### Environment friendly, for real -The diagram gives an overview of a typical development flow with -our Django hosting. +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. -We strongly recommend you to develop Django (like any other application) -with a version control system, even if you are just a single -developer. You can even use the [ungleich code -repository](https://code.ungleich.ch) for free -(you only need to [register an account](https://account.ungleich.ch)). +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. -## Components +Here at ungleich we offer you exactly 1 building block to build your +kubernetes clusters: The ungleich k8s node. -Depending on your stage of development, a Django hosting may contain -1 virtual machine (production), 2 virtual machines (staging + -production) and optionally a backup. +## 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 Django hosting is consisted with two parts of pricing. First part is a one-time, initial setup fee of 30 CHF, and the second part is a monthly payment for the managed VM at Data Center Light. For the latter you can calculate a standard VM price with 25 CHF monthly maintenance fee. +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. ## Getting started Below offers can get you started with your Django hosting.
