PgBouncer is a lightweight connection pooler for PostgreSQL that sits between your application and the database server, reusing a small pool of backend connections across many client requests. Without a connection pooler, PostgreSQL must fork a new backend process for every client connection, consuming memory and CPU as connection counts grow. On RHEL 8, PgBouncer […]
Introduction This guide explains how to Install Kotlin and Set Up a JVM Project on Debian 12 on Debian 12 Bookworm. Debian Bookworm uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control. Every command is designed for a minimal Debian […]
Apache Kafka is a distributed event streaming platform capable of handling millions of messages per second, making it a popular choice for real-time data pipelines, log aggregation, and event-driven microservices.

This tutorial stays on the systemd path throughout. Prerequisites Before you […]
RabbitMQ is a robust open-source message broker that implements the AMQP protocol, enabling asynchronous communication between application components.

On RHEL 8, RabbitMQ requires a compatible version of Erlang that is best installed from the official RabbitMQ Cloudsmith repository rather than the default RHEL […]
Introduction This guide explains how to Set Up a Node.js PM2 Process Manager on Debian 12 on Debian 12 Bookworm. Debian Bookworm uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control. Every command is designed for a minimal Debian 12 […]
Prometheus is a popular open-source monitoring system that collects metrics by scraping HTTP endpoints called exporters.
