Learn about migrating proprietary cloud infrastructure to OpenStack-based cloud infrastructure with hundreds of baremetal machines for cybersecurity experimentation in this 26-minute presentation. Explore the challenges of understanding Emulab-based proprietary clouds, mapping functions to OpenStack implementations while maintaining the web interface, and selecting optimal Ironic deployment options. Discover the journey from DevStack testing to Kolla-ansible deployment for OpenStack cluster implementation, including solutions for hybrid implementations connecting baremetal nodes with virtual machine instances. Follow along as the speaker shares experiences navigating limited Ironic support, collaborating with Chameleon Cloud testbed, and successfully implementing docker-based networking, flavor selection, node enrollment with various IPMI driver versions, and parameter mapping for seamless user migration.
