Clustered Services With Apache Whirr: From Dev Up
Email
The DevOps Zone is
presented by DZone with partners including ThoughtWorks Studios and UrbanCode to bring you the most interesting and
relevant content on the DevOps movement. See today's top DevOps content and be sure to check out ThoughtWorks Studio's Continuous Delivery Whitepapers and UrbanCode's Webinars.
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.
