Application Performance Engineering and SLAs
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 [...]

Tuesday, December 21, 2010
In the previous 2 posts we described several ways in which sub optimal performance engineering practices manifest themselves, as well as identified the lack of goal commonality between developers and performance engineers as one of the key reasons behind these sub optimal practices. In this post I want to look at the problem from a [...]

Monday, December 20, 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 [...]

Wednesday, April 28, 2010
Today was the first day of Interop 2010, and the conference & exhibition kicked off with a variety of discussions on performance engineering and exciting opportunities at Shunra’s booth #2056. Top of mind from speaking with attendees were infrastructure virtualization initiatives. Other themes included the need to manage effective data center relocation initiatives, and the [...]

Friday, March 12, 2010
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, February 19, 2010
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 [...]

Wednesday, February 10, 2010
Since Steve Jobs presented Apple’s new addition, the IPAD, the press and the blogosphere are trying to assess the real impact on the new gadget. Is it a passing fad, like the Newton or the attempts by IBM to implement a tablet computer or a real game changer that finally, after almost 30 of personal [...]

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 [...]

Wednesday, December 30, 2009
One of the topics we are frequently asked is to explain or clarify the difference between WAN Emulation and WAN Simulation. WAN Simulation methodology is a set of theoretical algorithms which are usually applied on a trace file. These algorithms aim to predict applications response times with different conditions and then applied to the captured [...]

Monday, December 28, 2009
Many of the largest networks today employ Multi-Protocol Label Switching (MPLS) for a myriad of reasons. So what are some of the key motivators that would entice an organization to make the leap to MPLS? Protocol neutrality, extensibility, adaptability and scalability are among some of the many reasons. Additionally, because MPLS was designed to openly [...]
