FCC to Propose Faster Broadband Speeds
A couple of weeks ago, I posted a blog dealing with a global study of Internet speed, where it was reported that the US is one of the few countries where the Internet is actually slowing down. On February 17, the Chairman of the FCC (Federal Communication Commission), Julius Genachowski, proposed a decade long program [...]

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, January 22, 2010
With the exponential growth of the Internet since the mid 90s, IP address space depletion has increasingly become a pressing concern. The reason that this issue has become more of a concern now than before is that the number of devices that can access the Internet has significantly expanded as compared to 10 years ago; [...]

One student at a time… Recently, I visited a company that develops and distributes software for Independent School District’s across USA. Their main product, originally developed for challenged kids, centers around dynamic computerized teaching and testing programs. This product proved to be so successful among this population that the company adapted it for other kids [...]

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
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 [...]

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. [...]

Friday, September 11, 2009
I have been meaning to address the impact that cloud computing has on performance engineering but haven’t had the time to rigorously tackle this issue. After all, there are serious implications both for vendors that deliver applications and services from the Cloud as well as enterprises that are rapidly migrating more and more services to [...]

Impact on Enterprise Application Performance In the current economic environment where growth is tough to come by, Business Ethernet Service (aka Carrier Ethernet, Metro Ethernet) is bucking the trend. A recent analyst report confirms the uptick in growth of these services for Business Applications: Source: Vertical Systems Group, March 2009 Service providers are reaching critical [...]
