application and network orchestration using heat & tosca
DESCRIPTION
The buzzwords Neutron, Heat, and TOSCA are spoken about quite often when it comes to the OpenStack - and many of us are still trying to make sense of the terminology and its place in the OpenStack world. Where OpenStack Neutron provides APIs for creating network elements, OpenStack Heat provides an orchestration engine for automating the setup and configuration of OpenStack infrastructure, while TOSCA is a standard for templating and defining application topology and policies (that form the basis for Heat). In this context, it really makes sense to put these all together to achieve application and network automation for OpenStack on steroids. In this session we will learn how we can use the robust combination of Heat and TOSCA to configure and control resources on Nova and Neutron in order to automate the network configuration as part of the application deployment. The session will include a demo and code examples that show how you can configure virtual networks, attach public IPs, set up security groups, set up load balancing and automatically scale up/down and more. You will leave this session understanding where Neutron meets Heat and TOSCA. This talk was delivered as part of OpenStack Paris summit - 2014 - http://openstacksummitnovember2014paris.sched.org/event/2b85b682ccaf3a5961e463b61e2403f8#.VFeuG_TF8mcTRANSCRIPT
