If you want to run DBpedia queries against your own cloud instance, I suggest you try
https://aws.amazon.com/marketplace/pp/B00KQPGYYA/ This has the data pre-loaded and you can be doing queries in ten minutes. There are other AMIs out there, but with perfectly matched hardware and software, this is the only one to meet the requirements for the AWS marketplace.
