So you have your cloud running, what now? Extend the devops agility from infrastructure to applications by learning how to use Brooklyn, the Apache-incubating project for application management. Create blueprints for applications to enable one-click deployment into Cloudstack, Docker, localhost, or other targets. Leverage your favourite server management tools, from Bash to Chef. Automatically change the deployment after it's deployed. Attach policies to support scaling, failover, and alerting in the way your application needs. In this session we'll show how with just a few lines of YAML, you can build powerful application blueprints by composing pre-existing components, from polyglot web stacks to big data tools such as Riak. We'll also cover defining new blueprints using custom scripts, configuring machine selection and runtime policies, and managing new locations such as Clocker -- the cloud of docker. About Alex Henevald Alex brings twenty years experience designing software solutions in the enterprise, start-up, and academic sectors.
