Operations

This section covers what happens after you ship: how to deploy Nexus to production, how to observe a running system, and how to tune performance when defaults are not enough.

What's in this section​

Four pages cover the operational surface of a Nexus application:

  • Deployment — OPcache, health checks, graceful shutdown, reverse proxy configuration, process supervision, and resource limits. Also links to platform-specific drill-ins for Docker, systemd, and Kubernetes.
  • Observability — PSR-3 logging, per-request MDC context, access logging, async log sinks, and PSR-14 event dispatch for integration with OpenTelemetry and custom metrics tools.
  • Performance tuning — Framework pre-binding, OPcache and JIT configuration, Swoole server settings, and Linux TCP kernel parameters. Includes measured benchmark data.

Prerequisites​

The operations section assumes you have a running Nexus HTTP application. If you have not yet built one, start with Getting started and the HTTP overview.

For worker pool deployments (multi-core scaling), the Scaling section covers worker pool architecture before you apply the deployment and observability patterns here.
