Cluster, Cloud, & Grid

Question

Choking on the following concepts and need confirmation or clarification: a cluster is an architectural pattern of server nodes being grouped together, and two competing instances of the cluster pattern are cloud and grid solutions.

Either way, what are the pros/cons of using clusters, clouds and grids (in relation to each other), and what criteria does one use to figure out which solution is best?

Thanks for any help!

Answer 1

Cloud and grid are just marketing term for the same thing and both are just clusters owned by somebody else.

You can only answer the question if you pick a definition of each - and that will answer your question!
