This will cause Azure to set up a cluster of machines preloaded with all the necessary OS, Hadoop and Storm components within minutes.
The components of a topology are called spouts and bolts.
Topologies don’t finish like other queries—they continue to execute until they’re suspended or killed.
In the Azure management portal, you can create a new HDInsight cluster and choose Storm as the type.
This could mean collecting and aggregating Web log data, user clicks from an application, telemetry from Internet of Things (Io T) devices or a host of other human- or machine-generated data.
I covered the case of doing basic Web log analysis using Hive on HDInsight in an article a year ago (msdn.com/magazine/dn890370).
