\section{Motivation}
\begin{frame}{Why Resilience Matters}
\begin{itemize}
  \item A single failing service can cascade across the system.
  \item Users notice outages within seconds, not minutes.
  \item Resilience is a business metric, not just an engineering one.
\end{itemize}
\end{frame}

\section{Patterns}
\begin{frame}{Circuit Breakers}
\begin{itemize}
  \item Fail fast when a downstream is unhealthy.
  \item Automatic recovery via half-open probes.
  \item Library: Hystrix / Resilience4j / Polly.
\end{itemize}
\end{frame}

\begin{frame}{Bulkheads}
Partition resources so that one failing dependency cannot exhaust threads or
connections for everyone else. Think \emph{water-tight compartments}.
\end{frame}

\begin{frame}{Retries with Jitter}
\begin{itemize}
  \item Exponential backoff to avoid thundering-herd.
  \item Add random jitter so clients don't synchronize.
  \item Always cap the maximum retries.
\end{itemize}
\end{frame}

\section{Observability}
\begin{frame}{Golden Signals}
\begin{itemize}
  \item Latency --- how long?
  \item Traffic --- how much?
  \item Errors --- how many fail?
  \item Saturation --- how full?
\end{itemize}
\end{frame}

\section{Case Study}
\begin{frame}{A Production Incident}
A misconfigured circuit breaker caused a 15-minute partial outage.
Root cause: timeout longer than the breaker's rolling window. Lesson:
test resilience configs as code, in CI.
\end{frame}

\section{Conclusion}
\begin{frame}{Recap}
\begin{itemize}
  \item Design for failure; it will happen.
  \item Instrument everything; measure the golden signals.
  \item Practice incidents in game days.
\end{itemize}
\end{frame}
