3rd Party System Scalability? – “How Slow Can They Go”
“How Slow Can They Go?” ...You definitely need to identify how slow your 3rd party providers can go before it starts to affect the performance of your sites. ... don’t try to replicate that traffic, just impair the actual traffic...

Friday, July 9, 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."

Friday, March 12, 2010
Virtualization has emerged as one of the leading technologies in today’s market; enabling businesses to more effectively scale operations to meet demand while significantly reducing costs at the same time. Everyone seems to understand what virtualization is, but it’s actually rather difficult to define because the term is used interchangeably to describe a plethora of [...]

In today’s Business section of the New York Times, there is an article by Brian Stelter (December 22, 2009) about a proposal by Apple computer to offer TV subscription packages via the Internet. The article points out that ABC and CBS are actively considering joining the Apple venture. Disney, who owns ABC, was the first [...]

Friday, November 6, 2009
As a corollary to last week’s blog about hosted load testing, I thought it would be interesting to explain a little about using a cloud-based test environment to perform pre-deployment testing for a cloud-based application. That sounds like a lot of clouds! What we are simply trying to understand is where and how to deploy [...]

Thursday, November 5, 2009
In the previous post we identified the Wide Area Network and the impairments that it introduces as a key reason for why a local user (let’s say in NYC) experiences a faster application than a user that is remote to his datacenter (let’s say in Tokyo). I also presented a question to the group: “We [...]

Friday, October 30, 2009
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 [...]

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. [...]

Friday, August 14, 2009
In my line of work, I get to assist many clients with analyzing the impact of an upcoming data center relocation on the performance of business applications. Many clients don’t know exactly what application performance to expect post the data center move. The main concern is that once all the applications start to operate across [...]
