Introduction Deploying configure traefik reverse proxy on freebsd 13 on a FreeBSD 13 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard […]

Load balancing distributes incoming client requests across multiple backend servers, preventing any single server from becoming a bottleneck and improving both throughput and fault tolerance. Nginx’s built-in load balancing is highly capable and available in the open-source version without any additional modules for most common use cases. On RHEL 8, you can configure Nginx to […]

HAProxy is a battle-tested open-source load balancer and proxy server that can distribute HTTP and raw TCP traffic across multiple backend servers with sub-millisecond overhead. On RHEL 8 it is available directly from the AppStream repository and integrates cleanly with firewalld and SELinux. This guide walks through installing HAProxy, writing a configuration that handles both […]
MinIO is a high-performance, S3-compatible object storage server designed to run on commodity hardware. It supports the full Amazon S3 API, making it a drop-in replacement for cloud object storage in private and hybrid environments. On RHEL 8, MinIO runs as a single binary with minimal dependencies, and its systemd integration makes it straightforward to […]
Compression reduces the byte size of HTTP responses, lowering bandwidth consumption and improving page load times. Nginx ships with built-in Gzip support through ngx_http_gzip_module, but Gzip has largely been superseded by Brotli for text content — the Brotli algorithm typically achieves 15–25% better compression ratios at equivalent CPU cost. On RHEL 8, Gzip requires only […]
