Running OpenStack on Amazon AWS, Alex Fishman
The document discusses deploying OpenStack on Amazon AWS, highlighting the benefits of using public clouds for development and testing environments due to their flexibility and cost-effectiveness. It addresses challenges like complicated network configuration and dedicated hardware requirements but introduces solutions like nested virtualization and overlay networks to bridge the gap. Use cases include multi-node system testing for developers and evaluation of OpenStack vendors for enterprises.

Editor's Notes
- #3 This talk is specifically geared toward developers, enterprise users that wish to try out different openstack versions and test features and configurations
- #5 What would you do if you’re An OpenStack developer Or a first time user that wants to evaluate OpenStack vendor propositions Or an enterprise user that just wishes to test specific features without modifying production environment
- #6 That’s why, it seems, that installing dev/test OpenStack environments in a public cloud can be a very desirable alternative
