Are you still arguing that I said Amazon sharded their database? Because I've re-read what I said, and what you said like 4 times and I can't see where I said they shard.

Actually, Amazon is kind of sharding their database: They encapsulate every kind of data into a program that manages it:

>What I mean by that is that within Amazon, all small pieces of business functionality are run as a separate service. For example, this availability of a particular item is a service that is a piece of software running somewhere that encapsulates data, that manages that data.
