1. With a provisioned iops the performance is almost identical to SSD, but yes probably I haven't done a side-to-side technical comparison. I only wanted to point out that I replaced one with the other and I had a good cut in cost.
2. Maybe it is just me, but I really think that some services like mongodb/redis does not require a big amount of system administration work to setup, I have actually wrote many python scripts to automate most of these tasks. but again maybe this depends on the country and the IT culture.
I see what you're getting at, but I'd like to point out that "not a big amount of system administration work" isn't worth money. Have you actually figured out how much it costs you to write many python scripts?
