Globalization led expansion of enterprises across geographies results in increase in functions,number of workforce, customers, volume of database, IT infrastructure and  network servers besides its size.  To cater for increase in the data that needs to be stored and processed for the proper functioning of their widespread offices, enterprises make use of multiple data centers and server farms.   However, these expansions and accessibility to the corporate networks challenges global organizations to maintain a secure and functional environment ensuring business continuity.

Enterprises with such multiple data centers and servers farms make use of load balancers to monitor the workload on servers. Load balancing is a methodology that helps to disseminate workload across numerous servers, computer cluster, disk drives, central processing units and network links.  With the use of dedicated hardware and software the appliances carry on the functions of tracking the front-end clients access services and forwards requests to the back-end servers to enhance website performance as well as reduce the burden of a particular server.

The technological enhancements having enabled the distributed project teams, vendors and remote workforce to access the corporate servers through their BYOD applications, leads to an increase in the work load and clogging of the corporate network.  It thus becomes imperative that the enterprises must make use of technology that will help servers to attain optimal resource utilization, reduce response time, increase throughput while averting overload. The load balancers ensures that the resources are not overloaded and enables consistency and enhanced network performance.

For  global enterprises that provide remote desktop access to their distantly located workforce, load balancers benefits them with 

  • Minimized load on individual systems with reduced  response time

  • Maximum  network utilization

  • Enhanced reliability and improved user satisfaction.

Further, for issues related to web securities, the load balancers routes the incoming and outgoing web traffic to servers which are involved in controlling access to websites. Besides, these also scans through the web traffic for any spyware, phishing attacks  and malicious activity on  the network thus ensuring security and business continuity even in the wake of adversities.

Depending on the organizational requirements and the availability of infrastructure, load balancers go through a series of steps to allocate tasks. However, this vary greatly for different networks and organizations .Advanced server load balancing appliances however, utilizes technology that is effectively executed with every network. The large enterprises often use custom built hardware-based load balancers, while smaller organizations usually makes use  of virtual load balancers.  

Leading application delivery networking service providers have developed innovative load balancers that leverages on  parallel multi-core processing to cost-effectively drive industry-leading function. With the changing technological scenario, these devices are made available on application delivery controller hardware and are engineered for virtual platforms like cloud and modern data centers. Further by enhancing application function this paces up the ROI for both small as well as large enterprises.
