A test that would use 100 lambda functions in parallel from each of the 4 regions and run for 5 minutes would cost about 3 USD. That should achieve a concurrency level of 100,000. That would be the most expensive test possible at the moment. Smaller tests are basically free.

Not to rain on anyone's parade but you could generate A LOT more load using regular old EC2 instances if all you had was $3...

Lambdas might be easier to launch and coordinate.

Actually not that bad... Great.

Why it is limited to 100,000 concurrent request ?

The default Lambda limit is 100 concurrently running Lambdas. AWS will raise this if you ask, I believe.
