ProActive OW2 features management of heterogeneous private Clouds, with burst capacity on Data Center and Public clouds. Offering full accounting and security, ProActive handles multi-tenant Cloud, and a smooth path for application migration to the Cloud thanks to comprehensive interfaces (Web Graphical Studio, CLI, Java and REST, User and Admin Portals). This presentation demonstrates the ProActive Cloud Automation product, especially in the framework of Open Stack. With OW2 ProActive Cloud Automation you can automate the deployment of your complex multi-VMs applications. You simplify self-service deployment, as well as automate the delivery of in production services. You set and control application elasticity with automated scaling-up and down, horizontally and vertically. Once you define the service deployment, you are able to deploy anywhere with workflow reversibility. With unified cloud management, applications execute on multi-vendor private, public and hybrid clouds. Industrial use cases are reported and showcased. Unique characteristics of ProActive are the capacity to manage both Virtual and Physical machines, to orchestrate native and virtualized applications, together with Workflow automation.
