The Feds May Soon Mandate Cloud Computing Usage
In a blog dedicated to Cloud Computing, published by InfoWorld, David Lithicum, the Cloud Computing guru, inform us that according to various published reports, the OMB (Office of Management and Budget) will mandate in the fiscal year 2011 (which starts in October 2010) that federal agencies not using cloud computing or making cloud computing part [...]
Continue reading...WAN Emulation vs WAN Simulation
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 [...]

Monday, December 28, 2009
I recently had the pleasure of attending the ITSEC Modeling and Simulation show in Orlando, Florida. This event featured the latest solutions in Gaming and Remote Learning for Dept of Defense clients deployed around the world. Based upon conversations with both the vendors and potential users of these products it quickly became evident that a [...]

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 reason [...]

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 your [...]

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 [...]

Thursday, October 22, 2009
In the first half of 2009 alone, the ten largest M&A transactions totaled a combined value of $244.6 Billion! History has shown that executing an acquisition is an opportunity to generate value; however successful integration completes the process. Many companies are integrating their applications as a direct result of a recent merger or acquisition.* Therefore, opportunities [...]
Continue reading...Building Applications for a Remote Datacenter Part 1. The network impact
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.

Thursday, September 17, 2009
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. [...]
