The FCC Invites You to Check How Slow Your Internet Access Is
The FCC just released a set of tools designed to test a user connection to the Internet,both for PC platforms (works on IE and Firefox) and applets for Iphone and other smart phones. Just access www.broadband.gov and you will be prompted to review the national plan to deploy broadband and invited to test your own [...]

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 [...]

Monday, February 8, 2010
I was approached a couple of days ago by one of our large customers, a major food manufacturer, to help them design a testing cycle for an hand-held device, to scan barcodes on their product’s pallets, as they are being unloaded from supply trucks into their regional depots. The devices utilize a LAN based wireless [...]

Friday, January 22, 2010
I was recently requested to support a Federal Agency that was tasked with validating the performance of an application to be globally deployed. Due to current events the timelines for testing and certification had become critical and the contractor responsible for the project was under enormous pressure to complete this engagement quickly. In conversations with [...]

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 [...]

Thursday, November 5, 2009
A data driven transactional application supports the execution of business processes. Each business process (such as book sale, update employee status, submit work hours, etc.) is comprised of multiple business transactions. A business transaction is described as the interaction and managed outcome of a well-defined step within a business process. A transaction is usually triggered [...]

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 [...]

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. [...]
