We are a group of young system engineers lead by Lorenz Brun which share their knowledge and resources
Lorenz Brun founded DolanSoft in 2010 with a few friends which were also interested in IT infrastructure. He is passionate about programming and especially distributed systems and IT security. He is responsible for most of the server infrastructure development, the main website and our internal managemant systems.
Marc Bärtschi joined DolanSoft in the late 2013 when he met Lorenz. He currently works as a computer scientist and learns more programming languages. He develops web applications and is involved in the design and operation of the DolanSoft infrastructure.
Timon Stampfli joined Dolansoft in 2010. He studies Computer Science at ETH Zurich. He is interested in many areas of Computer Science including development of applications and web applications, the design and structure of operating systems as well as methods to create secure and bugfree code. He also participates at competitions which are about solving algorithmic problems.
Every member of DolanSoft operates servers at home. These are all joined together and form the DS-Core cluster. We're currently setting up an edge cluster called DS-Edge, which will run all over the planet. We have 2Gbps symmetrical bandwidth, 160GiB RAM, ~150TiB bulk storage, 2 TiB hot storage and 48 cores over the whole server cluster. We have various more or less experimental technology integrated, including 40G InfiniBand links, custom BMC hardware and are working on a dedicated BLOB storage system.
The most important part about DolanSoft is the exchange of experiences and knowledge. Over time we gained quite a lot of operational insight into running clusters and developed custom software for certain parts which we'd like to share with people and we have a pretty large operational cluster for experiments and research into new things. We also dog-food the cluster, meaning that all our own service run on top of it, making it an interesting hybrid between a pure experiment and a full production cluster. If you're into infrastructure and want to take part, contact us!
We all have a Linux background and our infrastructure runs on a custom-engineered Kubernetes, has a ton of integrated service to use and supports hundreds of concurrent workloads, we currently run over 300 containers on our four physical hosts. We have infrastructure in place for hosting all kinds of websites and applications, email, network solutions and data analysis. We are a RIPE member with an active LIR account and run a worldwide global CDN and Edge computing network.
