Critical Applications Over the WAN
Critical applications over the WAN
Within the last few years, businesses have utilized separate systems and services to communicate and transact business with customers, partners and employees. The power of networking is being unleashed and applications are now being developed to harness the Internet.
Traditional applications such as order processing, billing and customer management have been integrated into complete Web-based supply chain applications. Web applications unify and streamline business processes from previously monolithic client/server applications. This is good news for SMBs, as Web-based applications offer the potential to reduce the need for expensive hardware and quicken time to market (TTM).
However, organizations that deploy Web-based applications are facing many challenges. For example, when an application is delivered over a WAN link, it is not uncommon for the link to not handle the increased traffic load effectively. The source of these WAN problems is associated with high traffic volumes, limited bandwidth resources and ISP outages.
Despite budgets for IT-related equipment and services, Web applications may not deliver the expected improvements in performance and reliability when delivered over the WAN. Other events, such as hardware failure, human error and natural disasters (earthquakes and hurricanes) can cause the WAN to fail.
