All rights reserved.  OpenStack, at least today, is targeted at hosting modern day distributed applications written for the cloud – This isn’t your grandpa’s server virtualization platform built for individual VM HA/Mobility  Sandbox environments  A place to research, learn and test CI/CD processes  PoC web applications along with ‘practicing’ the new DevOps methodology  A place to learn the whole cloud deployment framework, document, train, move to production  Development environments  Using the lessons learned in the sandbox phase: ‒ Build Dev, QA and production environments ‒ Apply CI/CD processes ‒ Slow-role Web application deployment either on ‘standard’ OpenStack or in conjunction with a PaaS deployment  Data Processing environments – Big Data clusters, etc..  Training systems – Cheap and fast to build and tear down for each class  Revenue generating applications – Vertical applications
