Both are possible, data center and on-premise. There are no hardware requirements but we recommend a 3 nodes setup to see the benefits of parallelism. Start with 64-128 GB memory, 4 disks and quad-core per node.

Spark performance really scale out with multiple machines. If there are 3 splits is 3 times faster with 3 workers. etc.
