Konfigurointienhallinta, also known as configuration management, is a systems engineering process for maintaining computer systems, servers, and software in a desired, consistent state. It is crucial in IT operations and DevOps practices, ensuring that systems are reliable, secure, and efficient. Configuration management tools automate the process of configuring and maintaining systems, reducing the risk of human error and ensuring consistency across environments.

Key components of configuration management include version control, which tracks changes to configuration files; idempotence, ensuring that applying a configuration multiple times results in the same state; and automation, which uses scripts or code to apply configurations. Popular configuration management tools include Ansible, Puppet, Chef, and SaltStack. These tools often use declarative languages, where administrators define the desired state of a system, and the tool ensures that the system matches this state.

Configuration management is essential for scaling IT infrastructure, as it allows for the consistent deployment of systems across multiple environments. It also facilitates disaster recovery and compliance, as it ensures that systems can be quickly restored to a known good state. By automating the configuration process, organizations can improve efficiency, reduce costs, and enhance the overall reliability of their IT systems.
