Experiments

The experiments I was included in took place under the umbrela of Web 2.0 engineering. Here is a list of experiments with short info about them.


API Call Limit in Cloud Infrastructures

Along with the rise of the popularity of the Cloud Infrastructures rise the popularity of using/accessing Web APIs from these new "fancy" infrastructures. Accessing the Web APIs from these infrastructures is more or less trivial job but unexpectedly it brings new challanges that have to be overcome.

For more details about the experiment read the following article: Cloud Computing May Decrease Your API Call Limit.
The experiment was led by Tomas Vitvar and supported by me and Jaroslav Kuchar.
