|

|

Entreprise-grade systems typically employ:
|

\vspace{1em}
|
||||
\begin{itemize}
|
||||
\item RAID
|
||||
\item Redundant power grid + UPS
|
||||
\item Redundant Internet connections
|
||||
\item Low-latency links
|
||||
\item ...
|
||||
\end{itemize}
|

\vspace{1em}

$\to$ it's costly and only worth it at DC scale

\frametitle{Distributed file systems are slow}

File systems are complex, for example:
|

\vspace{1em}
|

\begin{itemize}
|
||||
\item Concurrent modification by several processes
|
||||
\vspace{1em}
|

\item Folder hierarchies

\vspace{1em}
|

\item Other requirements of the POSIX spec

\vspace{1em}

Coordination in a distributed system is costly
|
||||
|

\vspace{1em}

\vspace{1em}

\item Retrieve an object from its key

\textbf{Coordination-free:}

\begin{itemize}

\item No Raft or Paxos

\vspace{1em}
