Idle workers waste RAM. Discover how uWSGI’s cheaper subsystem dynamically scales worker processes, saving memory while keeping performance high.
Nodemon’s auto‑restart mechanism is a staple of Node.js development. This article breaks down its architecture, requirements, operational checks, and failure modes, helping you decide when to use or replace it.
Nodemon's --exec flag replaces the default Node interpreter with any shell command, turning the watcher into a generic trigger—but it also shifts process lifecycle management onto you.
Fork duplicates process state cheaply via copy-on-write and shares file descriptors by reference; exec is what makes that copy safe to run a different program.
A diagnostic guide for PM2-managed Node.js apps stuck in crash loops: recognize the symptoms, correlate logs with restart counts, and apply targeted fixes for exceptions, port conflicts, OOM kills, and stale environments.
PM2 cluster mode uses every CPU core and supports zero-downtime reloads, but only if your app is stateless and handles SIGINT. Here is how to configure it with an ecosystem file and verify it works.
Manage multiple isolated Python applications on a single host using uWSGI Emperor mode. Learn how to configure vassals, secure the supervisor, and monitor your fleet.
Learn how to use uWSGI's 'cheaper' subsystem to dynamically scale worker processes, reducing memory usage during idle periods while maintaining performance during traffic spikes.
When one pm2 process is enough, what cluster mode demands from your app's state handling, and how to configure and verify zero-downtime reloads.
