Load Balancing Reducing Server Workload
The global business environment today is a widely networked one with servers, storage devices,
desktops, workstations, printers and telecommunication devices. Most of the large enterprises have
these infrastructure housed in data centers. The corporate network with all its components makes it
easy for the distantly located teams and offices to access applications and business information.
However, every business expansions and changing customer demands calls for further upgrading of the
existing hardware and software applications and increase in database leading to overloading of the
To combat issues of server overloads, enterprises especially the global organizations which use
multiple data centers for their vast data transfer and business traffic should invest in load balancing
solutions. These solutions will not only monitor the server workload but will also direct the users
accordingly. Wikipedia defines Load balancing as 'a computer networking methodology to distribute
workload across multiple computers or a computer cluster, network links, central processing units, disk
drives, or other resources, to achieve optimal resource utilization, maximize throughput, minimize
response time, and avoid overload.' With an optimal distribution of load across servers in the network
being necessary for maintaining a stable network, the load balancers addresses traffic spikes which
compromises the functionality, security, and capability of the network.
Further with technological innovations such as the BYOD or Bring Your Own Device system facilitating
easy and faster access to the corporate data, the servers tend to be overloaded. To bring about an
even distribution of the workload and processing of service request from various end-users, the data
center provider makes use of load balancers. Load balancing appliances are dedicated software,
hardware, or servers that form the critical components of a network. These appliances not only ensure
that the resources are not overloaded, but also enable the network to increase its consistency and
Commonly used to spread out the Internet service from multiple servers, web sites, large chat
networks, and File Transfer Protocol sites, NNTP and DNS servers, the load balancing solution
facilitates enterprises to-

Accelerates applications and prevents server sprawl with reduce server infrastructure costs
Further, the development of link load balancing solutions facilitates simultaneous use of multiple links.
This increases bandwidth availability, performance and reliability while reducing costs. Such load
balancers with intelligent traffic management system, handles the inbound and outbound network
traffic with real-time monitoring of the widespread corporate network. Server load balancing allocates
service requests across a cluster of servers. This process benefits enterprises with enriched
performance, better flexibility, scalability, accessibility and enhanced consistency.
