Autoscale for Azure HDInsight is now in preview

The auto-scale capability for Azure HDInsight is now available in preview. Autoscale automatically scales your Spark, Hive or MapReduce HDInsight clusters up or down based on load or a pre-defined schedule. * **Load-based auto-scale** uses several workload-specific metrics, such as CPU and memory usage, to intelligently scale your cluster between user-configurable minimum and maximum sizes based on the load. * **Schedule-based auto-scale** allows you to set your own custom schedule for cluster scaling. For example, you can set your cluster to scale up to 10 nodes starting at 9:00 AM and scale back down to 3 nodes at 9:00 PM on work days. * HDInsight * Features * Open Source * [ HDInsight](https://azure.microsoft.com/en-gb/products/hdinsight/)
