We are trying to evaluate HDP on Azure and HDInsights for relatively a simple use-case (Mostly based on Map Reduce as of now). Apart from cost I would like to know what all things should we know before concluding one is better fit than other?
difference for your use case would only be in cluster size. We recommend for clusters < 50 nodes to go with HDInsight, for anything above that, go with HDP. It also changes support structure, with HDInsight you call Microsoft for first level support, they escalate to us if necessary. With HDP on Azure, you call us directly. @Smart Solutions
