The final bullet point is super weird to me:

>Systems like CockroachDB must be tested in a real world setting. However, there is significant overhead to debugging a cluster on AWS. The cycle to develop, deploy, and debug using the cloud is very slow. An incredibly helpful intermediate step is to deploy clusters locally as part of every engineer’s normal development cycle (use multiple processes on different ports). See the allocsim and zerosum tools.

I'd like to know more details about why for this use case, AWS deployment is slower; bandwidth?
