Isn't the answer to "what do you do if a storm hits the bay area" simply "go back to sleep because all our servers are hosted in us-east-1"?

- simonebrunozzi 4y agoNah. Part of the narrative was that various Availability Zones (AZ) in a single region would be on "different flood plains", and be attached to different power grids. The essence of this design is that a single event, affecting either the ground (floods) or electricity (a grid), would not be able to single-handedly kill all AZs in an AWS region. Source: I used to share this stuff a lot, in public, representing AWS.
- cperciva 4y agoYeah, and nobody ever puts everything into a single AZ, right?
- simonebrunozzi 4y agoAh, good point. (hi Colin!)
- progman32 4y agoFor us the answer was just "get you and your loved ones to high ground, forget about the dang servers, let them go down, it's just computers". Refreshing. In any case the correct investment is in automated recovery systems and a business plan/partnerships that don't demand unrealistic SLAs.
