High Redundancy With 100% Uptime Fail-Over

Linux based Load Balanced Servers Cluster consists of multiple servers which distribute the website/application load among them in order to achieve maximum scalability and superior performance. This technique of load distribution evenly among a group of servers is known as server load balancing. Load balancing distributes traffic efficiently among the group of servers and ensures that no individual server is overburdened.

Linux Load-Balanced Server clusters function by dispensing a workload consistently over several back end nodes. The cluster is generally configured with numerous redundant load-balancing front end web servers. As each element in a load-balancing cluster has to offer full service, it can be considered of as an active/active HA cluster, where all accessible servers process requests.

There are several commercial uses of High-Availability Load Balanced Server clusters setup on numerous operating systems. We have implemented Load Balanced architecture on various Linux platforms such as CentOS, RHEL and Debian.

Linux Load Balanced Servers' Architecture

A typical Linux based Load Balanced servers' architecture consists of the following

  • 2 or more Web Servers of similar configuration.
  • 2 Database Servers
  • 1 Load Balancer (Server) or Master Server.

How it works

  • Each web server has a public IP assigned to it as well as an Internal LAN IP.
  • After the implementation of Load Balancing routing rules on the Load Balancer, Firewall rules are configured in order to allow traffic on the web servers to pass through the Load Balancer or Master Server.
  • The Load Balancer/Master Server balances traffic/load with equal distribution of traffic on each of the web servers who then pass on SQL queries to the database server.
  • With 2 database servers, real-time mirroring solution using Rsync and FAM modules for redundancy can also be implemented if required.
  • Any change on Database Server 1 is reflected immediately on Database Server 2.
  • If one of the Database Server in a cluster becomes unavailable as a result of failure or maintenance, another Database server immediately takes over the service and provides uninterrupted service within few seconds.
