It's a very good start to a complete minefield of competing solutions.

My first thought would be to differentiate between clustering and
replication, which will bring out many differences.

My second thought would be to differentiate between load balancing,
multi-threading, parallel query, high availability and recoverability,
which would probably sort out the true differences in the above mix. But
that wouldn't help most people and almost everybody would find fault.

IMHO most people I've spoken to take "replication" to mean an HA
solution, so perhaps we should cover it in those terms.
