Is your WAN Optimization Solution Meeting the Application Acceleration Challenge?

The economy is in a downturn and your IT budget is cut and now management is asking you to come up with ideas on how to save money and increase the business’s productivity. There a number of proven initiatives you can undertake and there are some newer ones you might be looking at to get the most benefit, but they all impact performance of applications over the WAN and that means that you need a WAN Optimization solution that can meet the challenge. Many organizations are consolidating file servers from the branch offices to the data center to reduce the number of underutilized servers and take advantage of server virtualization to get the most out of newer higher performing servers. Organizations are increasingly moving to Web-based applications to eliminate the need to install client software on the PC and to simplify application administration. A WAN Optimization solution helps in these cases by providing caching and compression to speed file transfers and acceleration for HTTP and SSL, but is that enough?

What’s Top of Mind for Australian CIOs Focused on the Data Centre?

August 7, 2009 at 12:00 pm PST

Dylan Morison, Cisco’s Data Centre Lead for Australia and New Zealand, participated in a series of CIO Roundtables with Dimension Data, EMC and VMware last week and in this video shares some of the common themes discussed.At a special roundtable for media hosted by Dimension Data, Paul Young the CIO of Ausenco joined and addressed how increased business agility was a key driver for virtualisation.

Load Balancers Don’t Die–They Get Virtualized for Optimal Application Delivery!

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, networking, and I/O virtualization. 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. It has been proven that virtualization of key data center assets increases 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 virtualized in the data center but virtualization of the server load balancer has been missing from this picture (in my humble opinion). Yes, those devices that sit peacefully in your virtualized data center don’t complain much and get the job done. They’re often thought of as distant cousins to those beefed up servers with their silky hypervisors… Why am I hot under the collar, you ask? Simply put: Why has the deployment of server load balancers with virtualized 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 unfamiliar with the value of a virtualized server load balancer or merely unaware of any load balancer with a virtualized architecture!

Is Application Acceleration Enough for Performance Over the WAN?

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.
