WAN OPTIMISATION I TECHNOLOGY
WAN optimisation as part of a major data centre consolidation project. The global healthcare leader eliminated eight data centres globally, saving approximately one million dollars per year in annual infrastructure costs and operation expenditures;
Prudential UK deployed WAN optimisation to enable a successful global virtualisation deployment (supporting over 13,000 thin clients). With WAN acceleration technology, all of Prudential UK’s remote locations experience consistent Citrix application performance, which previously not possible due to varying degrees of WAN bandwidth, latency, and packet loss;
ARM Holdings drastically improved its employee productivity through more effective information sharing and real-time collaboration between its vastly geographically distributed data centre locations, as a direct result of WAN optimisation. The world’s leading semiconductor intellectual property supplier has gained an increase in bandwidth of at least 100 percent globally, representing hundreds of thousands of pounds per year.
With some applications costing close to £6,000 per user to deploy, companies can end up spending a significant amount of money rolling them out. It is not uncommon for IT managers to spend a third of the total project investment on upgrades to IT infrastructure in order to support the new applications. However, an investment in network optimisation can often cost less than one percent of the total cost of deploying a single enterprise application. At the same time, WAN optimisation improves application performance so that Recovery Point and Time Objectives are met while end users are happy with the performance of key productivity applications. Thus, WAN optimisation can provide a rapid return on investment, with the added benefit of increased end-user satisfaction.
Going the distance
As companies become more and more reliant on business critical information, it becomes increasingly imperative to protect resources against unexpected loss. However, backup, replication and recovery involve the transfer of large volumes of information across long geographical distances, which require a significant amount of WAN bandwidth. Many business tasks react poorly when in the presence of high latency, resulting in application timeouts and subsequent database synchronisation problems.
To accommodate the enormous volumes of data, IT managers can deploy large WAN links between data centres, which are forced to handle hundreds of megabytes or terabytes of data. Given the price of WAN bandwidth, this can become an extremely expensive component which often doesn’t solve the true underlying performance problems.
By dramatically improving WAN efficiency, WAN optimisation helps companies capitalise on end-user satisfaction, enjoy the flexibility of increasing geographical distances between data centres and keep pace with growing disaster recovery demands – all without requiring costly increases to WAN bandwidth. When deployed correctly, the benefits of WAN optimisation are extremely tangible – from improved data transfer times to significant cost savings.
Furthermore, by overcoming the common performance challenges that so many organisations face, WAN optimisation ultimately helps companies abide by compliance demands and enables them to take full advantage of their virtual applications, thus providing a robust and rapid return on investment.
