In communications or computer systems, a configuration of a system refers to the arrangement of each of its functional units, according to their nature, number and chief characteristics. Often, configuration pertains to the choice of hardware, software, firmware , and documentation.
The Promise theory of configuration maintenance was developed by Mark Burgess, [16] [17] [18] with a practical implementation on present day computer systems in the software CFEngine able to perform real time repair as well as preventive maintenance.
The following tables describe attributes of notable version control and software configuration management (SCM) systems that can be used to compare and contrast the various systems. For SCM software not suitable for source code , see Comparison of open-source configuration management software .
Uses YAML to express reusable descriptions of systems. Bcfg2 Software to manage the configuration of a large number of computers using a central configuration model and the client–server paradigm. The system enables reconciliation between clients' state and the central configuration specification.

A soft or digital copy of the piece of software (program) is needed to install it.
The term configuration item (CI) refers to the fundamental structural unit of a configuration management system. [1] Examples of CIs include individual hardware or software components. The configuration-management system oversees the life of the CIs through a combination of processes and tools by implementing and enabling the fundamental ...
In complex continuous delivery environments and/or software as a service system, differently-configured versions of the system might even exist simultaneously in the production environment for different internal or external customers (this is known as a multi-tenant architecture), or even be gradually rolled out in parallel to different groups ...
