| Grid | Cluster |
| A Grid uses software to auto-gen the APT file to use a subset of resources based on compute node use. | A Cluster is a group of Datastage servers where The admin/designer designs the APT file to use the compute node resources available |
| Under the GRID software, it will look at the utilisation of the compute nodes on the grid and pick which machines are underused and dispatch the job to these nodes. | If you have a group of 25 compute nodes, the designer would write his APT file to use 4 compute nodes. If those nodes are busy, Datastage would still try and use those nodes |
