title: How to use Azure HDInsight getting charged less
body: <p>I am using Azure with Pay-as-you-go subscription. I had experience in creating Spark cluster via HDInsight for myself, and got charged more than expected. After that, I searched how to use it in an economical manner and found people normally delete their clusters to save cost. I wonder if there are any other ways for individual users to use Spark cluster with small expenses. Is there other subscriptions that I can use to save cost? Thanks in advance.</p>
