\section{Introduction}
\subsection{e-LAN}
\begin{pframe}
A high speed dedicated network.
\begin{itemize}
\item Secure transfer of sensitive data.
\begin{itemize}
\item No need to set up a VPN.
\end{itemize}
\item High throughput, low latency.
\begin{itemize}
\item Access to remote storage using NFS.
\end{itemize}
\end{itemize}
\bigskip
Bringing data to computational facility is not always convenient.
\begin{itemize}
\item Data management concerns.
\begin{itemize}
\item Copies tend to lead their own life.
\end{itemize}
\item Size.
\end{itemize}
\end{pframe}
\subsection{Use case: cluster scale out}
\begin{pframe}
Dynamic and transparent \emph{scale out} of a local cluster:
\begin{itemize}
\item Based on system load.
\item Access to remote nodes with \emph{local credentials}.
\item Access to local resources.
\end{itemize}
\bigskip
In other words, the remote nodes should behave just like local ones.
\medskip
\pause
We see the same requirements:
\begin{itemize}
\item Secure transfer.
\begin{itemize}
\item Lots of unencrypted traffic within a cluster.
\end{itemize}
\item High throughput, low latency.
\end{itemize}
\end{pframe}
\section{Situation sketch}
\subsection{Local situation}
\begin{pframe}

\caption{Schematic overview of our local situation.}
\end{figure}
\end{pframe}
\subsection{Use cases}
\begin{pframe}
We focus on three main areas:
\begin{itemize}
\item Full genome sequencing data analysis (high volume).
\item Bacterial strain typing (low latency).
\item \emph{De novo} assembly (long run time).
\end{itemize}
\bigskip
But also:
\begin{itemize}
\item Experimenting with new queues and settings.
\begin{itemize}
\item Easy to give a couple of dedicated nodes for someone to test with.
\end{itemize}
\end{itemize}
\end{pframe}
\subsection{Local security}
\begin{pframe}
You might have a strict security policy.
\begin{itemize}
\item Make sure the VMs in the cloud do not have direct access to the
internet.
\item All traffic is routed back to the institute (LUMC).
\end{itemize}
\bigskip
Regard these nodes as being in your own network.
\begin{itemize}
\item No deep packet inspection on NFS traffic for example.
\end{itemize}
\end{pframe}
\subsection{Present situation}

\end{pframe}
\section{Further plans}
\subsection{Federated cloud}
\begin{pframe}
This is a first step to full virtualisation of local clusters.
\begin{itemize}
\item Scaling out to other locations than SURF.
\end{itemize}
