#2Goad was our entry in this year's Gopher Gala and was built in under 48 hours by a team of 4.

#3Any plans to include a way to "script" the urls, types of requests, etc?
Load testing is more than hammering a single URL thousands of times.

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.

Definitely! Not something we could have done properly in 48 hours though :)

Actually not that bad... Great.
Why it is limited to 100,000 concurrent request ?

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...

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

Lambdas might be easier to launch and coordinate.
