AWS Advocates Eventual Consistency, and I believe offers less than 3 nines guaranteed uptime on many products.
We've been taught to build distributed system with unreliable componens and temporaral JIT eventual consistency.
Of course we can run production cloud-scale operations on unreliable systems. And single power supplies without ECC or RAID is pretty low on my list of things that cause outages. Most big hadoop/cassandra shops are running without raid and without redundant power.

- late2part 9y agoI suspect your and my definition of regular setups is different. My regular setups are stateless and automatically installed and configured.
