Load Balancers and Business Continuity The competitive environment prevalent in the business world has provoked enterprise to expand globally. The expansion has given the global enterprise a vast range of multi-lingual and multicultural consumer base along with multinational business environment with the large number of offices, branches and partners spread across the globe. To be connected across these various locations and to be accessible to all the stakeholders, enterprises have used technological innovations to build their corporate networks. The corporate networks are made up of best of the breed servers, storage devices, printers, IT infrastructure, telecommunication devices. With corporate websites on internet servers supporting these network, today's business environment can ensure carrying out any function from a distant location be it operational management, financial transactions, data base access, customer service management. Such 24/7 access to the corporate data from any location poses issues overloading the servers. networking professionals provide enterprises with load balancers to facilitate distribution the load across its servers. 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.� To achieve this enterprises use Load balancer’s which includes software, hardware, multilayer switch or DNS servers which forms the dedicated critical components of the network.
