As much as we try to avoid performance problems, they do happen. It is inevitable. But it is possible to learn to react fast, and in some occasions fast enough that the impact on the end users is negligible. Despite operators' best efforts, 73% of performance issues are reported by users, according to "APM: Getting IT on the C-Level's agenda" report by Aberdeen Group.

The goal of application performance monitoring is to ensure and improve the quality of applications as perceived by the end users. Getting to the root of the problem quickly is only part of the solution. When we ask vario... (more)

Using a Performance Management Database to Identify Network Problems

Two weeks ago I wrote about how the world's largest exporter of dairy products uses SAP to support their huge delivery chain of dairy products.

Filling the Citrix Visibility Gap with an Application-Aware Network

Citrix XenApp or XenDesktop is a perfect fit for lowering the costs of desktop management and simplifying access to the hosted applications from any device. Last week we discussed some challenges to application performance monitoring (APM) introduced by Citrix. Apart from getting yet another component in the data center to take care of, the virtualized application delivery becomes "black boxed" from the APM perspective. It gets harder to isolate the fault domain to the network, the infrastructure, or the applications themselves. In the previous post we presented the case of The ... (more)

Part 4 | Five Steps to Improve E-Commerce Performance for Increased Sales

Our client TescaraHats (name changed for commercial reasons), a European market leader in manufacturing customized hats, set up an e-commerce site in hopes of increasing its market share and boost its sales. This did not happen. TescaraHats learned quickly that there is much more to e-commerce performance than simply putting an e-commerce service online. In Parts 1-3 of our e-commerce performance mini-series we discussed why focusing on page rank is not enough and that we should look at your performance at the back end and potential network-related problems. In Part 4 we will s... (more)
