\frametitle{How to be resilient (the hard way)}
|
|
|
|
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
|
|
\end{itemize}
|
|
\vspace{1em}
|
|
Coordination in a distributed system is costly
|
|
|
|
\vspace{1em}
|
|
Costs explode with commodity hardware / Internet connections\\

Only two operations:

\vspace{1em}
|
|
\begin{itemize}
|
|
\item Put an object at a key
|
|
\vspace{1em}
|
|
\item Retrieve an object from its key

\end{itemize}

\vspace{1em}

{\footnotesize (and a few others)}

Sufficient for many applications!

\begin{itemize}

\item No Raft or Paxos
|

\vspace{1em}

\item Internal data types are CRDTs
