\begin{block}{\textbf{deuxfleurs.fr} -- a libre hosting association with a vision}
|
|
``Shifting the current structure of the Internet from a world of a few very large service providers, to a world where services are hosted by a variety of smaller organisations.''
|
|
\end{block}
|
|
|
|
|
|
\begin{block}{Our goals}
|
|
\begin{itemize}
|
|
\item To propose performant \& reliable libre services for the masses
|
|
\item To host and administer our infrastructure ourselves
|
|
\item To allow members to contribute storage/compute nodes
|
|
\item Resilience: for availability \& the sysadmins' sleep
|
|
\item Conceptual simplicity to ease onboarding \& demistify hosting
|
|
\end{itemize}

\begin{frame}{The lacking state of the practice}
|
|
|
|
\begin{block}{Object storage fitted our needs}
|
|
\begin{itemize}
|
|
\item Distributed by design
|
|
\item Objects are replicated
|
|
\item Conceptually simple
|
|
\end{itemize}
|
|
\end{block}
|
|
\vfill
|
|
|
|
\begin{block}{Existing object stores did not}
|
|
\begin{itemize}
|
|
\item Too specific / complex
|
|
\item Resource hungry
|
|
\item Hidden constraints
|
|
\end{itemize}
|
|
\end{block}
|
|
\vfill
|
|
|
|
We developed Garage, an object store with minimal functionality.
|
|
|
|
It works, and serves our static sites and media.

\begin{itemize}

\item Distributed data store
|
|
\item Based on DynamoDB object store (P2P!)
|
|
\item Modular data types/protocols with CRDTs:
|
|
\begin{itemize}
|
|
\item Done: objects (media, static sites, backups...) via S3 API
|
|
\item To do: e-mails via IMAP protocol, and more

\textbf{Pros:}
|
|
\begin{itemize}
|
|
\item Compiled and fast
|
|
\item Features prevent usual mistakes:
|
|
|
|
strongly typed, immutable by default, ownership instead of GC...
|
|
|
|
\item Best of several paradigms:
|
|
|
|
imperative, OO, functional
|
|
|
|
\item Good libraries for network programmings:
|
|
|
|
serialization, http, async/await...
|
|
\end{itemize}
|
|
\column[t]{.4\columnwidth}
|
|
\textbf{Cons}:
|
|
\begin{itemize}
|
|
\item Steep learning curve
|
|
\item Long compilation times
|
|
\item Compiler rage
|
|
\end{itemize}
