First of all let me introduce myself….English native now Americanized who has been in the valley for 15 years, having worked with likes of Cisco, Bay, Sun , Brocade, Neterion and now Cisco again, with firm roots in Server, Storage, Network and I/O virtualization. Consequently, due to how social media and Web 2.0, changes how we work, play and interact daily, I have decided to take up blogging, especially around Data Center Virtualization which has now become a #1 priority for I.T, since it has been proven that virtualization of key data center assets does increase efficiency by harnessing the power of underutilized resources which in turn lowers CAPEX and OPEX, leading to better scalability and overall IT agility.To date, server, storage and network infrastructure products have been virtualize in the data center but what has been missing in this picture (in my humble opinion) has been virtualization of server load balancer…yes those devices which sit peacefully in your virtualize datacenter don’t complain much but get the job done…often thought of as distance cousins to those beefed up servers with their silky hypervisor…..So, why am I hot under the collar you may ask?…simply put..why has the deployment of server load balancer with virtualize architectures for efficient and optimal application delivery not been on the data center manager’s radar? After all, they understand the benefits of server, storage and network virtualization… correct?. Maybe it is because they are not familiar with the value of a virtualize server load balancer or merely unaware of any load balancer with a virtualize architecture! Read More »
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 »
