> You should be able to deploy end to end to Production in less than a minute.
When I was at AWS (RDS) our end-to-end production deployment process was 7 days. We were also pulling $25million/day or so in profit. I'm sure that number is much higher now.
There's a large difference between what the theoretical "right" thing is from a textbook perspective, and what successful engineering teams do in reality.
edit: besides, it doesn't even make sense in this context. I have 100 servers talking to the database. I need to create an index, ok, add it to the code. Deploy to server 1. Server 1 adds the index as part of the migration process, and let's say it's instant-ish (not realistic but whatever). Do the other 99 servers now panic because there's an unexpected index on the table?
