Setting Up VRRP and Keepalived for Load Balancer Redundancy with HAProxy
To ensure high availability and redundancy in our load-balancing environment, we can leverage VRRP (Virtual Router Redundancy Protocol) with Keepalived. By configuring VRRP across two servers, we can assign virtual IPs (VIPs) that automatically migrate between servers in the event of a failure. This setup enables seamless failover, with each server acting as both a…
Understanding VRRP: Ensuring Network Resilience through Redundancy
The Virtual Router Redundancy Protocol (VRRP) is a network protocol designed to increase the availability of routing paths in a network. By creating a virtual router, VRRP allows multiple routers to work together, ensuring that if the primary router fails, a backup router can take over seamlessly. This failover capability is essential in networks where…
Understanding HAProxy: A Key Tool for Load Balancing and High Availability
HAProxy, short for High Availability Proxy, is a powerful and widely used open-source load balancer and reverse proxy solution. It plays a central role in ensuring that websites and applications can handle heavy traffic loads effectively and remain available, even when certain servers experience issues. What Does HAProxy Do? HAProxy is designed to distribute incoming…
Exploring the Pros and Cons of High Availability
High Availability (HA) is a key strategy in IT systems to ensure that applications and services remain accessible and operational, even during unexpected disruptions. Implementing HA can make a noticeable difference in the reliability and user experience of your systems, particularly when paired with tools like HAProxy, VRRP, and DNS. Let’s dive into the primary…
