Branch office users are crying out for better performance of business-critical applications over the WAN. The impact of latency and congestion as well as limited bandwidth is affecting their productivity. Research shows that business performance starts to decline when applications exceed a 5 second delay in response times. This makes a job of IT departments challenging as they look to support business services and mitigate revenue loss while saving on bandwidth costs and getting the most out of their current enterprise resources as they work with limited budgets. The inability to prevent performance issues before end-users are impacted is the top challenge for managing application performance over the WAN. How to deal with the increase in voice and video traffic is another, as well as the lack of visibility into the end-user experience. Organizations are also challenged by increasing transfers of large files between network locations and an increase in complexity of applications.
At CiscoLive! one of the more common questions I was asked was around the future of enterprise IT from an organizational perspective. To me, the shift in the conversation is an indicator that folks are continuing down the path of data center virtualization and are trying to get a better understanding of the long-term impact. Conversations usually centered around the continuing role of IT in the enterprise and what kinds of skill sets will be needed in this new world. A number of folks in IT management roles asked some version of “with IaaS/PaaS/SaaS, will enterprise IT go away?”–I could not really tell if they viewed this a negative or not. So, are we going to get to the point where someone in purchasing is buying services they same way they buy janitorial services?
WAN Optimization is a top technology under consideration by IT organizations according to research by The Info Pro in their Technology Heat Index report. Many Service Providers are creating WAN Optimization services to meet the requirements of customer who want WAN Optimization but prefer to outsource management. See Cisco Press Release. Organizations know that they can reduce IT expenditures as well as deliver new services more effectively by consolidating IT resources in the Data Center and by deploying WAN Optimization they can still give branch office users LAN like application performance. Whether organizations deploy WAN Optimization themselves or get it as a managed service they need to be able to justify the budget expenditure and that means being able to fully understand their requirements and being able to measure the performance improvements delivered of deployment of WAN Optimization.

People are moving back to cities to escape suburban sprawl. Industries are consolidating to a small number of mega-brands. And after years of distributed systems anarchy, IT is consolidating equipment and facilities back to a more efficient, controllable, centralized model. Sound familiar? People are even talking about the ‘virtual mainframe’, VDI to thin clients, and water cooling.It’s not about pastel-colored, refrigerator-sized boxes this time. The average data center houses hundreds of rack units of servers, storage and networking equipment, miles of cabling, and aircraft-engine class AC fans. And that’s a challenge — actually, several: Read More »
If your organization relies on Microsoft Office SharePoint® Server 2007 for global collaboration among thousands of employees across hundreds of widely dispersed locations, read this WAN optimization customer testimonial provided by Monsanto – a global agricultural company that uses technology to help farmers succeed while reducing agriculture’s impact on the environment. Monsanto has deployed Cisco WAN optimization solution across 107 sites and is taking it to the next phase. Let me first quote some highlights:Microsoft Sharepoint application acceleration: The Monsanto IT team measured the time to open a 13.8 megabyte Office Excel file on a server in St. Louis from an office in Cambridge, Massachusetts. Without Cisco WAAS, opening the file through Office SharePoint Server 2007 took 4.5 minutes. With Cisco WAAS, opening it the first time took just 1.3 minutes—a performance increase of about 71 percent. Opening the same file subsequently, after it was cached, took just 8 seconds.WAN optimization: Overall bandwidth usage has decreased by 50 percent in the sites using Cisco WAAS, which means that the same link can accommodate about twice as much traffic as in the past without becoming saturated.
