Cluster Workflows Overview

Cluster Workflows Overview

You can use a workflow to create a cluster that runs Mapping and other tasks on a cloud platform cluster.
A cluster workflow contains a Create Cluster task that you configure with information about the cluster to create. The cluster workflow uses other elements that enable communication between the Data Integration Service and the cloud platform, such as a cloud provisioning configuration and a Hadoop connection.
If you want to create an ephemeral cluster, you can include a Delete Cluster task. An ephemeral cluster is a cloud platform cluster that you create and use for running mappings and other tasks, then terminate when tasks are complete to save cloud platform resources.
You can use a cluster workflow with the Amazon EMR or Microsoft Azure HDInsight cloud platforms.
To create a cluster on Cloudera Altus, you create a workflow with Command tasks that perform the tasks that a cluster workflow automates. For more information about creating a cluster on Cloudera Altus, see the article "Implementing Informatica Big Data Management with Ephemeral Clusters on a Cloudera Altus Cluster" on the Informatica Network.
