Continuous configuration automation (CCA) tools enable the description of configuration states, customization of settings, software binaries deployment, and configuration state reporting. These tools are a programmable framework on which configuration and provisioning tasks can be codified, versioned and managed like any other piece of application code — frequently known as 'infrastructure as code.' Many of the tools in the market provide a repository to store and manage configuration content but can be integrated with or use (code) revision control systems in use by application development teams. System administrators and application developers use CCA tools to programmatically manage the configurations of applications, servers, middleware, databases and other IT infrastructure for both on-premises and cloud data centre environments. Most CCA tools have both an open-source and commercial offering.
