Very big article that basically buried the core difference: zero trust or some "trusted transaction manager". Moving from the second to the first is very trivial - just make it based on distributed consensus of nodes that are run by separate entities, may be even several different cloud vendors. AWS also doesn't have some interesting things from crypto-world - smart contracts, that are just like lambda functions that couldn't be altered in any way and could be trusted by third-party. They have Nitro Enclaves, this is close, but quite hard to use.
