Cloudera Director And AWS Spot Instances

David Han shows off some new features in Cloudera Director 2.5 to help when building Hadoop clusters on AWS spot price instances:

You can configure Spot instances in Cloudera Director’s instance templates. These instance templates contain a flag indicating whether Spot instances should be used, as well as a field specifying the bid price for those instances.

Each instance group in the cluster template includes a field that indicates the minimum number of instances required in that group for the cluster to be considered successful. Cloudera Director will continue with bootstrapping or growing a cluster if the minimum count for each instance group is satisfied. Spot instances should not be used for instance groups that are required for the normal operation of the cluster, such as HDFS DataNodes. Instance groups configured to use Spot instances should set their minimum number to zero with the expectation that the instances may not be provisioned due to the Spot bid price being lower than the Spot price.

If you’re able to take advantage of spot instances, you can end up saving a pretty good amount of money.
