description Overview

PM2-cluster

PM2-cluster is an extension of PM2 designed specifically to utilize all available CPU cores for Node.js applications. It automatically manages worker processes, ensuring that if one worker crashes, the others continue serving traffic while the failed one is restarted. This is crucial for maximizing throughput and maintaining uptime under heavy load for JS backends.

Sidekiq

Sidekiq is the standard for background job processing in the Ruby on Rails ecosystem. It uses Redis as a message broker to handle asynchronous tasks like sending emails, generating PDFs, or interacting with third-party APIs. Sidekiq is known for its efficiency and ability to handle high volumes of jobs using multi-threaded workers, making it a staple for any production Ruby application.
