* Most orgs take a sprint to write load tests in a separate tool/language (Jmeter, for example).
* Re-using integration and end-to-end tests or even Postman requests for load lets you release fully tested software sooner
* Let your teams use the language and tool they know to write the tests, then we containerize and scale that in your EC2 account, because by-the-minute hardware is cheap, dev-hours spent in Jmeter are expensive.
* The dev teams/QA folk can do testing rather than waiting for the "Jmeter" specialist
Let me know if you would like a demo
Unfortunately, haven't used it beyond demo. Yet.
