You don&#x27;t have to think about running or scaling a cluster -- it&#x27;s a service that you dump data into and supports a pretty decent set of SQL.<p>Cost is probably cheaper as well, but I don&#x27;t have apples to apples numbers to compare.<p>But the main point being, if you get your data in the cloud as .json.gz, you can use them all fairly easily.  Maybe one solution fits 90% of your needs, and another one the other 10%.  That&#x27;s what I&#x27;m finding at least.
