Testing 3G Hand Held Inventory Devices using Shunra Virtual Enterprise (VE) Suite
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 [...]

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.

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.

Tuesday, July 21, 2009
Anyone developing on the WPF platform surely knows the Snoop utility by Pete Blois. It is absolutely awesome and I cannot imagine developing WPF applications without it. However, there is a problem with it. One cannot snoop WPF framework elements nested too deep. By too deep I mean somewhere around 60 layers. Trying to snoop [...]

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 [...]

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 [...]
