The Need
Today's network-based; information-centric economy compels organizations to rethink their fundamental business models and strategies. The focus of the shift is clearly towards enhancing operational efficiencies, quality and globalization. This trend necessitates re-engineering of traditional business processes, effective merging of application technologies and implementation of new information systems. 

The emerging business dynamics have led to constant changes in the way organizations use Information Technology. Current international trends reflect the vast opportunities manifested by the Internet. Globally, IT budgets are increasingly being allocated towards developing internal and external net initiatives. For instance, in 1999 only, over 12% of all US Company IT spends were directed for web initiatives. Given the growing focus in this area, this percentage is expected to be 27% by 2004, when web spending in the US alone is estimated to exceed $ 300 billion.

Network infrastructure of a corporation is the prime step in building a huge e-business. The reliable & flexible features of the network enable business on the net to achieve a competitive advantage. 

The networks supporting e-business are critical and needs to perform round the clock. Complexities on these networks are on the increase as the numbers of applications running on the network are increasing and the inherent characteristics and demands of these applications are different and sometimes even contradictory. In addition, business applications are specific to each organization, and the criticality of the applications changes over a period. Thus, for e-business to achieve maximum network uptime, it needs to be continuously designed, monitored, managed and secured to provide an environment of risk free commerce and completely security. It enables organizations to enjoy the benefits of Virtual LANs, e-LANs, Intranets and Extranets. By designing and deploying cutting edge technology applications on the network, organizations can reap the benefits of high performance, commerce, increased sales and decreased costs, leading to contented customers and increase in Shareholders value.
