Understanding the Benefits of Load Balancing
Load balancing has specific significance in busy networks, especially when it is difficult to foresee the
number of requests that will be issued to a server. It not only increases the performance to servers, it
also leads to their optimal utilization and ensures that no particular server is burdened. Wikipedia
defines load balancing as “a computer networking methodology that distributes workload across
multiple computers or computer clusters, network links, central processing units, disk drives, or other
resources, to achieve optimal resource utilization, maximize throughput, minimize response time, and
Load balancing facilities enterprises to

Server Load Balancing
Server load balancing is the process of allocating service requests across a cluster of servers. There are
many benefits to this process, these include:
It is when the processing power of servers are used intelligently, that the highest performance is
achieved. End-user service requests can be directed to the servers that are least busy by advanced
server load balancing products. This consequently results in quick response times.
Server load balancing creates fault tolerance for back-end servers and high-availability pairs for load
Content inspection rules permits the sending of requests for specified web pages to particular groups of
Failed servers are automatically identified by constantly scrutinizing the health of the back end servers.
The failed servers can be detached from the cluster until they recover.
Server load balancing is easy to install and configure, and include a secure, web-based graphical user
interface which provides you with visual alerting, health monitoring and cluster diagnostics.
Better flexibility and scalability
Both enterprises and service providers need the flexibility and transparency to deploy additional servers
quickly. Many exhaustive content applications scale beyond the point where a single server can offer
satisfactory processing power.
Server load balancing has the ability to enhance application availability. In the event of an application
failing, load balancing automatically redistributes end-user service requests to other servers.
Server load balancing also averts planned outages for software or hardware maintenance from
disturbing service to end users. Distributed server load balancing also provides disaster recovery services
service requests to backup locations, in cases where failure renders the primary site as inoperative.
As servers are expected to provide high performance, high availability, and secure and scalable solutions
to support all applications at all times, server load balancing are a widely adopted solution to all
performance and availability problems.
