To scale the control and networking nodes, you will need to install and configure control and networking services on additional nodes. In our installation example in Chapter 2, RDO Installation, Packstack was used to do the installation. In a production environment, a more complex configuration management setup should be used; Packstack is intended for demonstration and proof-of-concept installs and is incapable of maintaining an OpenStack installation long term. Foreman, Staypuft, and Triple-O are all more robust options that can handle a longer-term installation. There are also other open source projects and commercial products that have these long-term management capabilities.

Packstack does not include direct functionality to duplicate control and networking services. Although requiring some manual intervention, it can help get plenty of the heavy lifting done for us. Let's take a quick, high-level overview of what it will take to shoehorn Packstack...
