As the WAN matures, with advances in robust applications, cloud delivery and other technologies, optimization tools have had to keep pace. It is no longer just about classic compression and protocol acceleration. The new role is about application performance, delivering everything from application visibility to quality of service (QoS) control. In short, the focus is on true WAN governance.
The proliferation of cloud computing will have a major impact on the WAN and, specifically, on the performance of business-critical applications that cross the WAN. Data centers and companies alike must be prepared to address this shift since, with cloud computing, the WAN traffic matrix becomes much more complicated and stresses the network like never before, requiring movement of massive amounts of data.
