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 [...]

WAN symptoms within Cloud type Data Centers – Why would we test something like this?

Monday, January 25, 2010

WAN symptoms in question are latency, packet loss, disconnects, bit errors, etc. usually exist on Wide Area Networks and as a result cause applications performance degradation. But our WAN’s essentially are LAN’s connected with each other and those connections impose geographical distance between those LANs, thus creating “WAN behavior”. Inside individual LANs those issues happen [...]

Impact of Latency on Cloud Computing

Tuesday, December 8, 2009

0 Comments

The new buzzword around the IT block is “Cloud Computing”, the ability to avoid deploying costly infrastructure on each location by contracting a “virtual” infrastructure environment from dedicated vendors. Need to expand? Just call your provider and double your server capacity and triple your storage. However, we may need to apply a sobriety test, where [...]

Building Applications for a Remote Datacenter Part 2 Application Efficiency Metrics

Thursday, November 5, 2009

1 Comment

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 [...]

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, [...]

Building Applications for a Remote Datacenter Part 1. The network impact

Tuesday, October 13, 2009

1 Comment

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. [...]
