The use case is the TPC-C benchmark but executed not on a high-end server but on a lower-spec virtual machine that is I/O limited like for example, with AWS EBS volumes.

Auto-scaling is often presented as a panacea for performance problems, but, even if it is properly implemented (which is, of course, better to be tested), it just assigns a price tag for performance. The answer to this challenge is service virtualization, which allows simulating real services during testing without actual access.
