Building High-Availability LVS Clusters with Keepalived

Overview Keepalived provides high availability for LVS load balancers through VRRP (Virtual Router Redundancy Protocol). The solution enables automatic failover of the virtual IP address between master and backup nodes, ensuring uninterrupted service when the primary scheduler fails. Core Concepts V...

Understanding Keepalived: Architecture, Components, and Deployment Guide

Overview Keepalived is an open-source software solution designed to provide high availability and load balancing for Linux-based systems. The application monitors services and servers, automatically failing over when primary resources become unavailable. This capability ensures continuous service de...

Deploying LVS with Keepalived for High-Throughput Network Infrastructure

Distributing incoming network traffic across multiple backend servers mitigates single-point bottlenecks, enhances bandwidth capacity, and ensures continuous service availability. When individual nodes exceed their processing thresholds, clustering mechanisms route requests simultaneously. This arch...

Implementing High Availability with Keepalived and VRRP

Keepalived Overview Keepalived is a routing software written in C that provides load balancing and high availability capabilities for Linux systems and Linux-based infrastructures. The software achieves two primary functions: Load Balancing - Distributes network traffic across multiple servers High...

Implementing High Availability with Keepalived and Virtual IP Addresses

Keepalived is a software solution for achieving high availability in network services. It is primarily used to ensure service continuity and prevent single points of failure, commonly applied in load balancing and failover scenarios. Core Concepts of Keeepalived VRRP-Based Implementation: Keepalived...

Using vrrp_script, track_script, and notify Hooks in Keepalived for Priority Control and Service Failover

vrrp_script provides health/eligibility probes that can adjust a VRRP instance’s priority at runtime. By returning a non‑zero exit code, the script can penalize priority via weight, making the local node less likely to be elected master. track_script links these checks to a specific vrrp_instance. n...
