\subsection{Scalability Architecture}
|
|
|
|
\subsubsection{Horizontal Scaling}
|
|
|
|
\begin{itemize}
|
|
\item Stateless backend: Deploy multiple instances behind load balancer
|
|
\item Session storage in Redis cluster (3-node quorum)
|
|
\item Database read replicas for high-read workloads
|
|
\end{itemize}
|
|
|
|
\subsubsection{Caching Strategy}
|
|
|
|
\begin{itemize}
|
|
\item User profiles: Redis cache (5-minute TTL)
|
|
\item JWKS: In-memory cache (1-hour TTL)
|
|
\item DID Documents: CDN + Redis (15-minute TTL)
|
|
\end{itemize}
|
|
|
|
\subsubsection{Rate Limiting}
|
|
|
|
Prevent abuse via token bucket algorithm:
|
|
\begin{itemize}
|
|
\item Login attempts: 5 per 15 minutes per IP
|
|
\item Token requests: 100 per hour per client
|
|
\item DID resolution: 1,000 per hour per IP
|
|
\end{itemize}
|
|
|
|
\subsection{Benchmarking}
|
|
|
|
\textbf{Test Setup}: 8-core CPU, 16GB RAM, MySQL 8.0, Redis 7.0

|
|

|
|

|

DID Resolution & 3,000 req/s & 12 ms \\ \bottomrule
