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.

If there are 3 splits is 3 times faster with 3 workers. etc. --- [Visit Topic](https://discourse.ros.org/t/slice-and-dice-large-ros-bag-files-on-hadoop-and-spark/2314/3) or reply to this email to respond.
