Hosted Load Testing II
My friend Mark Tomlinson from HP recently wrote an informative blog about “Understanding the language of hosted load testing.” The blog touched on two competing approaches to application performance testing that were referenced as “behind the firewall” and “outside the firewall”. Behind the firewall testing usually means testing in a lab environment such as a [...]

Tuesday, October 13, 2009
This series of posts is about the day after a data center move. Now that the data center is remote, how does this paradigm shift impact the way we should develop, test, deploy, monitor and troubleshoot applications. I will try to cover as many topics as possible, but the main focus is still going to be around the role application performance management plays in this new paradigm.

In the previous post http://www.shunra.com/shunrablog/index.php/2009/08/14/data-center-relocation-questions-and-answers-part-1/ I presented an example of a common performance problem with applications that host executables on a remote shared drive. As common as that problem is, it is usually a legacy problem, most new applications follow a more best practices architecture usually involving a web based front end for the application. [...]

The BBC reported recently that British technology was pushed to the extreme as the Southern part of England, including the London metropolitan area, was blanketed by a rare snow storm. In London, bus services were canceled and hundreds of thousands turned to the web to find alternative means of transportation. Web sites for train and taxi [...]

Thursday, January 29, 2009
Building applications on a local area network masks many performance problems that only surface when applications interact with remote users on a wide area network. One common problem is when remote users experience slow web pages that load content (table records, images, videos, PDF files, widgets). These pages tend to perform much slower for remote [...]

Tuesday, December 16, 2008
The performance of web pages is an important topic for many IT managers. Speed, security, appearance, and reliability are common metrics for measuring performance. What is a mystery to many is what affects those metrics. The article, Web Performance Matters, Slowness Considered Harmful does a good job explaining key network influences on websites, common misconceptions [...]
