ELB scale-out/scale-up test

This test goal was to determine ELB is to scale out / scale-up at what time when a load is applied to the ELB. But results of the tests it was completely different from the behavior of ELB that I was assumed in advance. As there is a possibility that there was a problem in the test method, the test I do again. This test result is I keep a record for interesting.
