HAProxy (High Availability Proxy) is a battle-hardened open-source load balancer and proxy for TCP and HTTP workloads. Where Nginx load balancing is sufficient for simple round-robin HTTP distribution, HAProxy provides a richer feature set: advanced health checks with multiple failure thresholds, ACL-based routing, Layer 4 TCP load balancing for non-HTTP protocols (MySQL, Redis, SMTP), detailed […]
Introduction This tutorial covers How to Set Up Database Backups with Percona XtraBackup on SLES 16 on SLES 16. SLES 16 (SUSE Linux Enterprise Server 16) is SUSE’s enterprise-grade Linux distribution.

Rate limiting is a server-side defence that restricts how many requests a client can make within a time window. Without rate limiting, a single IP address or bot can flood your server with thousands of requests per second — crashing your application, exhausting your database connection pool, or triggering denial-of-service conditions. Nginx provides two rate […]
Load balancing distributes incoming requests across multiple backend servers, preventing any single server from becoming a bottleneck and providing horizontal scalability and fault tolerance. Nginx supports four load balancing methods natively: round-robin (the default), least connections, IP hash (session persistence), and weight-based. The upstream block defines the pool of backend servers and their weights, and […]

Unpatched software is the leading cause of server compromise. The majority of publicly disclosed vulnerabilities already have patches available by the time attackers start actively exploiting them — the window between patch availability and active exploitation has shrunk from months to days. Manually patching servers is error-prone and inconsistent at scale. Automatic security updates ensure […]
