Console’s review

· Reviewed by David Mytton

What we like

Uses SO_REUSEPORT built into the Linux kernel for connection distribution, eliminating significant overhead. Handles crash restarts, graceful shutdown, monitoring, deployments for multiple applications. Shared HTTP cache across workers. Allows integration of databases, APIs, and multiple frameworks within a single app server.

Tradeoffs

Supports observability through Prometheus and Jaeger, but needs extra work to get data into services like DataDog unless you ingest through OTLP.
