1. February 2011
The following article by Jim Metzler covers the value in setting SLAs between IT and the business units that it serves. It does a nice job at mapping the role of SLAs to the application performance engineering process. What resonated well with me was a quote from Jim taken from “Alice in Wonderland” – “If [...]

20. December 2010
The time is right for Application Performance Engineering. It’s a simple statement, but a powerful one that will change the existing application lifecycle management paradigm. At Shunra, we have been working hard, together with our partners, at developing and defining a new performance management model that completes the existing APM frameworks. This post is a [...]

21. October 2010
None of us want our sites to crash like the Chase site outage in mid September. I’m not privy to the details of that site crash, but I can tell you that many sites degrade under peak user traffic unexpectedly and eventually crash. Why? It’s often incorrectly performed scalability tests. Over the years, I’ve met [...]

9. July 2010
The holidays are not typically on our minds this early in the year given that it is currently early July and over 100 degrees Fahrenheit in portions of the Eastern USA. On the other hand, if you have an ecommerce site that has changed since the Holidays last year, then perhaps you should be thinking about gauging your traffic and applying a peak load to the site. Let’s not forget that even the biggest logos have had issues during peak traffic. Many large sites including HP’s outage in 2009, Wal-Mart’s outage in 2006, in 2008 Bloomingdale’s and J. Crew went down, and many others have made the news in recent years because their sites were note ready for the traffic. "...Load testing without taking latency into account gives the site an unfair advantage during load tests, which does not exist in the real world."
