The practice of keeping computer systems, servers, and software in a desired, consistent state is an example of configuration management. Configuration management is all about preventing problems so that you don’t have to deal with them later. You may, for example, ensure that your test and production settings are identical. You’ll have less issues with applications once they’ve been deployed this way than you would if the environments weren’t identical. Because you know what exists in the original environment, configuration management allows you to correctly recreate an environment with the necessary configurations and applications.
