Sessions at PuppetConf about Apache Whirr on Friday 23rd September

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.

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 your cloud provider of choice, or even from a list of machines in a text file. This discussion will show how you can create support for a new service without writing code. We'll review the an interaction module based on JSON formatted node lists and Puppet modules, in context of a working Cassandra configuration. You'll understand pros and cons of this approach, and see where it makes sense to use master vs masterless Puppet mechanisms.
