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 […]
Apache’s mod_proxy module turns Apache into a powerful reverse proxy and gateway, forwarding requests to backend application servers, other web servers, or balancer clusters. Unlike Nginx’s reverse proxy (which is native), Apache’s proxy functionality is modular: mod_proxy handles the core proxying, mod_proxy_http handles HTTP/1.1, mod_proxy_balancer provides load balancing, and mod_proxy_wstunnel handles WebSocket tunnelling. On RHEL […]

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 […]
