Load Balancer
The Load Balancer Add-On for Red Hat® Enterprise Linux® provides support for Transmission Control Protocol (TCP) load balancing independent of applications. It's composed of 2 major components: the Linux Virtual Server (LVS) and the Piranha Configuration Tool, a management tool with a GUI.
Linux Virtual Server
- To balance the load across the physical servers
- To check the integrity of the services on each physical server
It does this by redirecting service requests from virtual IP addresses to the physical servers based on 1 of 8 supported load-balancing algorithms. The backup LVS router monitors the active LVS router and takes over if it fails.
Piranha Configuration Tool
The Piranha Configuration Tool is a web browser-based GUI tool that provides a structured approach to creating the configuration file for LVS. It offers easy and intuitive GUI-based management as an alternative to tedious manipulation of lvs.conf using a text editor.
LessBENEFITS & FEATURES
Maximum efficiency and high availability
The Load Balancer Add-On balances the IP load across a set of physical servers based on a preordained algorithm, thus evenly distributing the load among available servers for maximum efficiency and high availability.
The virtual servers monitor the health of services running on the physical servers using send/expect scripts. If a service on a physical server malfunctions, the active LVS router stops sending jobs to that server until it returns to normal operation.
Piranha offers a GUI for centralized management of both virtual and physical servers and for the services running on the physical servers. It also provides both configuration and monitoring tools.
