Once you purchase a Load Tester™ license, load up to the number of concurrent users specified by the license can be generated from outside your network using our Amazon EC2-based load engines. At the click of a button you can configure enough computers to generate hundreds of thousands of simulated users, all billed directly from your Amazon EC2 account.

| Amazon EC2 Rental | $10/computer/hour |
The number of virtual users that can be generated from a single cloud-based load engine, and hence the additional cost of generating load from the cloud depends on the test case and test case configuration. The average capacity of a cloud engine is in the 800VU to 1500VU range.The numbers below are meant to give you an idea of the typical cost.
| Simultaneous Virtual Users |
Avg Number of Load Engines | Total Engine Cost/Hour |
|---|---|---|
| 100 | 1 | $10 |
| 1,000 | 2 | $20 |
| 5,000 | 4 | $40 |
| 10,000 | 7 | $70 |
| 25,000 | 17 | $170 |
| 50,000 | 34 | $340 |
| 100,000 | 67 | $670 |
To get started generating load from outside of your network first signup for the Amazon EC2 service, and then follow this tutorial to configure Load Tester™.
* The number of virtual users that can be generated externally is the same as can be generated internally on a particular license. For example, a 100VU license can generate 100 concurrent virtual users regardless of where those users originate.
