In her PhD project she developed metrics to compare forest data structures, with an application in molecular structure comparison. Working as a postdoc in cancer research on molecular structure prediction, she found her way to Brooklyn and Berlin.</p>

<p>A founding member of Unikernel Systems (later acquired by Docker), Martin has been involved in a number of library operating system projects since 2014, including the Rumprun unikernel and MirageOS. He is a co-author of Solo5, a secure execution environment for unikernels, and joins Robur in 2018 to continue his work towards creating secure software that “just works” and other ambitious projects.</p>

<p>Mindy ran the first MirageOS unikernel in the public cloud in 2014. Mindy has worked extensively on the MirageOS TCP/IP network stack and various protocol implementations, and is a member of the project's core team. She managed the release of MirageOS's latest major version.</p>
|

<p>Mindy is interested in freeing software from unnecessary dependencies, including monolithic kernels. While she finds testing and bug-fixing rewarding, her true goal is to apply techniques that remove entire bug classes to broader classes of computation. Memory safety isn't just for application code!</p>

We worked on reproducible builds for <a href="https://opam.ocaml.org">Opam</a> packages and <a href="https://mirageos.org">MirageOS</a> - with the infrastructure being reproducible itself. Reproducible builds are crucial for supply chain security - everyone can reproduce the exact same binary (by using the same sources and environment), without reproducible builds we would not publish binaries.</p>

<h2>Brief robur and MirageOS introduction</h2>
|
||||
<p><a href="https://mirageos.org">MirageOS</a> is an operating system, developed in OCaml, which produces unikernels. A unikernel serves a single purpose and is a single process, i.e. only has the really needed dependencies. For example, an OpenVPN endpoint does neither include persistent storage (block device, file system) nor user management. MirageOS unikernels are developed in <a href="https://ocaml.org">OCaml</a>, a statically typed and type-safe programming language - which avoids common pitfalls from the grounds up (spatial and temporal memory safety issues).</p>
|
||||
<p><a href="https://robur.coop">Robur</a> is a collective that develops MirageOS and OCaml software with open source license. It was started in 2017, and is part of the non-profit company <a href="https://techcultivation.org">center for the cultivation of technology</a>. We received funding from several projects (<a href="https://prototypefund.de">prototypefund</a>, <a href="https://pointer.ngi.eu">NGI pointer</a>), donations, and commercial contracts.</p>

<h2>Deploying MirageOS unikernel</h2>
|
||||
<p>To run a MirageOS unikernel on your laptop or computer with virtualization extensions (VT-x - KVM/BHyve), you first have to install the <code>solo5</code> and <code>albatross</code> packages. Afterwards you need to setup a virtual network switch (a bridge interface) where your unikernels will communicate, and forwarding.</p>

<p>That's it. Albatross has more features, such as block devices, multiple bridges (for management, private networks, ...), restart if the unikernel exited with specific exit code, assignment of a unikernel to a specific CPU. It also has remote command execution and resource limits (you can allow your friends to execute a number of unikernels with limited memory and block storage accessing only some of your bridges). There is a daemon to collect metrics and report them to Grafana (via Telegraf and Influx). MirageOS unikernels also support IPv6, you're not limited to legacy IP.</p>

|

<p>MirageOS is a software suite to build custom-tailored operating systems from (mostly open source) small individual libraries. It has been developed since 2009 at the University of Cambridge, UK and is written in the programming language <a href="/Our%20Work/Technology-Employed#OCaml">OCaml</a>.</p>
|
||||
<p>It compiles the necessary OCaml libraries into a unikernel - a small operating system, each built for a certain purpose. For each unikernel we can pick from hundreds of permissively licensed open source libraries which implement network protocols, storage on block devices, or interfaces to network devices via the hypervisor or host operating system. As we only put into each one exactly what is needed, each unikernel is fast; instantly booting and, as there is less code base, it is easier to maintain and keep secure.</p>
