Ask ten engineers which configuration management tool to use and nine will say Ansible. We went the other way. Our fleet, both on-premise and cloud, for clients who expect things to just keep running, is managed by CFEngine. Here are the ten reasons why, and where Ansible still earns
Running out of space on your Linux VM? No problem, LVM (Logical Volume Manager) and VMware vSphere make disk resizing straightforward, even if you've added an entire unpartitioned disk to a volume group. In this post, I'll walk you through the process of resizing LVM managed
Ever wished your AI assistant could actually remember things between conversations? Not just the current chat, but the architectural decisions you made three months ago, the patterns your team agreed on, or that obscure networking fix you discovered at 2 AM? We built exactly that, a persistent, searchable long-term

Monitoring HAProxy is essential for maintaining reliable load balancing infrastructure. Prometheus provides powerful metrics collection, alerting capabilities, and seamless Grafana integration for visualizing HAProxy performance and health. Why Prometheus for HAProxy? Prometheus offers: * Pull-based metrics - Prometheus scrapes HAProxy metrics endpoints * Time-series database - Store historical data for trend analysis

In dynamic environments where services scale up and down automatically, static HAProxy configurations become a management burden. Consul integration enables HAProxy to automatically discover and route traffic to healthy service instances without manual configuration updates. Why Consul + HAProxy? The combination provides: * Automatic service registration - Services announce themselves to Consul * Health-

Managing HAProxy configuration traditionally requires editing files and reloading the service. The Data Plane API transforms HAProxy into a dynamically configurable load balancer with a RESTful interface, enabling real-time configuration changes without service interruption. Why Data Plane API? The Data Plane API provides: * Runtime configuration - Add/remove backends and

Mutual TLS (mTLS) provides strong authentication by requiring both client and server to present certificates. This guide shows how to configure HAProxy for mTLS to secure API endpoints, internal services, and zero-trust networks. What is mTLS? In standard TLS, only the server presents a certificate. With mTLS: 1. Server

When applications misbehave behind a load balancer, HTTP headers are often the culprit. This guide shows you how to debug, inspect, and manipulate HTTP headers in HAProxy to troubleshoot web application issues. Why Header Debugging Matters HTTP headers control critical aspects of web traffic: * Client IP forwarding (X-Forwarded-For)

HTTPS is no longer optional - it's a requirement for modern web applications. This guide shows how to integrate HAProxy with Let's Encrypt for fully automated TLS certificate provisioning and renewal, giving you secure HTTPS without manual certificate management. Overview The integration involves: 1. HAProxy serving HTTPS

DNS is critical infrastructure - when DNS fails, nothing works. This guide shows how to use HAProxy to load balance DNS queries across multiple resolvers or authoritative servers, providing high availability and improved performance for your DNS infrastructure. Why Load Balance DNS? DNS load balancing offers several benefits: * High availability: If
