Applications, Applications, Applications
I have been asked by a colleague “Why would someone use Application Virtualization?” You may already know that adopting the likes of Application Virtualization is not an easy task. Many applications are simply not built to be deployed in such an environment. Not to mention all the other challenges faced within the IT organization. One [...]

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 [...]

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 [...]

Friday, September 4, 2009
As part of our service offerings at Shunra’s professional services, we help our clients analyze the performance ROI of WAN acceleration. We also wrote a best practices paper about it here http://www.shunra.com/uploads/pdf/WAN-acceleration-whitepaper-031909.pdf. Which is why I was very interested in learning about 2 new developments from Microsoft. These developments provide improved performance for branch office [...]

Examples of latency sensitive applications In the previous post http://www.shunra.com/shunrablog/index.php/2009/08/14/data-center-relocation-questions-and-answers-part-1/ I shared some of the questions that clients typically ask me during the performance analysis service in a data center relocation project. One of the most popular question, especially at the beginning of the project is “which applications are the most sensitive to network latency?”. [...]

Wednesday, March 25, 2009
One of my favorite partners to work with is LoadTester. Not only are they competent and efficient, but they are nice and will tell you what they really think. Their latest update on HP’s latest release of LoadRunner 9.5 goes into a lot more detail than any readme file will, with perspective and colorful commentary [...]

Friday, March 6, 2009
Earlier this week, Shunra announced the release of a new product, VE Desktop for HP Software 5.0. This product is embedded into HP’s LoadRunner 9.5 and Performance Center 9.5 products and from the surface, looks a lot like a previous feature in LoadRunner called Mercury WAN Emulation (MWE). Because of the obvious similarities, there have [...]
