Mr. David White writes for Network World about the importance of WAN Optimization and governance to application performance. In the past WAN Optimization has been focused on compression and protocol accelerations, but today’s focus is on application performance from visibility to quality of service control which Mr. White states as “true WAN governance.”
Many IT teams think about application performance first and foremost when there is a problem. Other times it may be due to a new project or when making significant environmental changes. As is the case with a new project, such as adopting cloud computing, IT must make sure the network is ready to handle increases in bandwidth usage and web browsing traffic. Some companies may purchase more bandwidth but others will use WAN Optimization to better monitor and regulate network traffic. More bandwidth or better bandwidth management alone is not the total solution, enter WAN governance.
WAN governance is about aligning business priorities and IT priorities over the global WAN. Mr. White points out that WAN governance allows the business to identify business critical applications on the network and their performance. Applied properly and when it takes into account the whole IT picture, WAN governance allows for IT to manage the cost/performance tradeoffs at the IT level.
