Thread limits for Azure Load Testing

Question

Azure Load Testing (Preview) has a limit of 250 threads per Engine Instance. Each test can only run up to 45 Engines, so the theoretical maximum number of concurrent sessions that can be run is 11,250.

I need to simulate 120k concurrent users. Is there a suitable workaround to do this with ALT?

Answer 1

I think it's better to contact Azure Support for the details.

In the mean time be informed that you don't need 3rd-party providers to run a JMeter test without any limits, given you have a subscription you can

• kick off several virtual machines
• install JMeter on these machines
• run your test in distributed mode

which is pretty much what Azure Load Testing is doing under the hood
