Sure you can. In fact, almost every eventually consistent database is built on a collection of strongly consistent single systems. Eventually consistent systems are even frequently built on top of consistent distributed systems, and some of the largest infrastructure on the planet works just like that.
- marknadal 12y agoI'm not quite sure where you get that. A strongly consistent system requires other database peers to lock on writes, which isn't needed for eventual consistency. See http://aphyr.com/posts/313-strong-consistency-models http://aphyr.com/posts/313-strong-consistency-models for some great descriptions of how it works, he is quite the expert at testing these things.
