+\section{Introduction}

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\begin{frame}{A very casual motivation}
+
+
+\begin{center}
+\Large
+I want to host \textbf{resilient web services} with \textbf{acceptable performance} on commodity hardware behind \textbf{household networks}.

+\begin{frame}{Context}
+
+\textbf{Resilience}: Ability to recover quickly from failures and changes.
+\vspace{1ex}
+
+Only achievable through distribution of the hosted applications across several physical locations.
+\vfill
+
+
+\begin{block}{Application = \textbf{computations} on \textbf{data}}
+\begin{itemize}
+ \item \textbf{Computation}: Stateless; easy to distribute \& orchestrate.
+ % where it is performed does not matter as long as the application's state is accessible R/W
+ %Computation units are "easy" to distribute and orchestrate.
+
+ \item \textbf{Data}: Stateful; hard to distribute \& full of trade-offs.

+\begin{frame}{The problem}
+
+% \textbf{Path dependency}: existing data stores are built for data centres.
+
+% $\implies$ They assume good inter-node connectivity.
+% \vfill
+
+\begin{center}
+\Large
+Can we design an available data store tailored for adverse network conditions?
+\end{center}
+
+\end{frame}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% Maybe more framing of the context. What kind of data storage? Object vs Block vs what?
+% \begin{frame}{``Stateless'', ``serverless'', and the elephant in the room}
+
+% It seems easy to deploy \& administer web services nowadays ...
+
+% Because the inherent complexity is shadowed by proprietary ``cloud'' solutions.
+
+% The IT crowd can gloss over ``statelessness'' \emph{ad nauseam} ...
+
+% But storing \emph{state} remains an open research problem.
+
+% Data storage is either:
+
+% \begin{itemize}
+% \item A single point of failure;
+% \item Delegated to proprietary solutions;
+% \item Pain.
+% \end{itemize}
+
+% Today, we will review networked storage's history, and discuss open research questions.
