They're both marketing buzz words so definitions may vary. In my
experience, subtle differences exist.
Grid: Fixed resource pool consisting of multiple nodes for running
batched (not realtime) computing tasks. Facilities generally used by
single entity.
Cloud: anonymous resource pool that will scale near-real time per
demand. Physical facilities are shared between multiple users. Details
of
infrastructure (most notable: geographical location) are hidden
from end users
Cancer research is generally run on a grid.
Seti@home is a hybrid.
Amazon EC2 is (by definition ;-)) a cloud service.
