This document discusses different options for deploying OpenStack including Packstack, TripleO, Fuel, and OpenStack Ansible.
Packstack provides an all-in-one installation but lacks support for high availability and complex configurations. TripleO uses OpenStack native projects like Ironic but has a very high learning curve and is mostly CLI-driven. Fuel provides a wizard-driven deployment but has a non-flexible architecture. OpenStack Ansible is flexible, container-based, and easy to customize but network and OS installation must be done manually with no vendor support. The document recommends OpenStack Ansible for development/proof-of-concept and Fuel or TripleO for production-ready deployments.
