Clustered Services With Apache Whirr: From Dev Up

Apache Whirr is an incubator project focused on simplifying management of distributed services such as Hadoop, ElasticSearch, and Cassandra. Using Whirr, you can in a single line startup a cluster from scratch in the cloud provider of choice, or even from a list of machines in a text file. This discussion will unveil how Whirr works from an internals perspective. We'll discuss how Whirr interacts with the jclouds multi-cloud library to provision sets of nodes, and the layers on top that handle configuration and orchestration. You'll see the java code needed to write support for new services, and see how Whirr can hook into external configuration management tools such as Puppet.
