In this final module, we recap the key NGINX optimizations you’ve learned to secure and accelerate your web server.
OptimizationDescriptionBenefits
Rate LimitingUse limit_req_zone and limit_req directivesMitigates DDoS attacks and bot scraping
CachingConfigure proxy_cache or fastcgi_cacheReduces backend load and speeds up pages
CompressionEnable gzip (or Brotli) with gzip onShrinks response size and accelerates delivery
Keep-Alive ConnectionsTune keepalive_timeout to reuse TCP socketsLowers latency and CPU overhead
Worker ProcessesAdjust worker_processes and worker_connectionsHandles thousands of concurrent requests
LoggingCustomize access_log and error_log formatsImproves monitoring and debugging
Monitoring with DatadogInstall the Datadog agent for real-time metricsAlerts you to performance issues
Enabling gzip compression can reduce response times by up to 80%. Always benchmark your asset types to find the optimal compression level.
