Cloud Computing is computing resources and access platforms which are stored, hosted and carried out in a foreign (3rd party) data server configuration.
Cluster computing is one subset of Cloud Computing.
Grid computing is another.
Virtualization is a core component of Cloud Computing which divides the available resources on a given hardware and/or software configuration into specific representations for specific users, organizations or communities.
