What do you mean? The dollar cost for HRD is the same as MS. >I know we could save > some CPU hours by using Python 2.7 concurrency feature if we move over to > HRD. There is loss and there is gain.

We do have a fix - the HRD :-) Seriously, to make MS more consistent and reliable, you'd need to synchronously replicate the data across machines and data centers and that is exactly what MRD.
