Configuration management data

Configuration management refers to the process of systematically managing, maintaining, and controlling the configuration of software, hardware, and infrastructure systems to ensure consistency, reliability, and traceability throughout their lifecycle. It involves tracking and documenting changes to system settings, software versions, dependencies, and configurations, as well as automating the deployment and management of these configurations using specialized tools. Key concepts in configuration management include:

• Configuration items (CIs): These are the individual components (for example, servers, network devices, applications) whose configurations are managed
• Version control: The process of maintaining versioned records of configuration files, scripts, or settings
• Automation: Using tools to apply and enforce configurations across systems to ensure consistency
• Change management: Tracking and managing changes to configurations to minimize errors and downtime
• Configuration drift: When systems deviate from their intended configuration due to manual changes or updates

Configuration management ensures that systems are deployed and maintained in a known, consistent state, reduces configuration drift, and improves the efficiency of software development, deployment, and operations, including facilitating the quick restoration of systems to a known, working state after a failure. It also provides detailed logs and version histories of changes for auditing and compliance and enables rapid scaling of systems with consistent configurations in large infrastructures.

Configuration management data typically includes:

• Server configuration management: Managing and automating the configuration of web servers
• Network configuration management: Managing the configurations of routers, firewalls, and switches
• Infrastructure as Code (IaC): Using code to define and manage infrastructure configurations
• Application configuration management: Managing application-specific configurations (for example, environment variables, database connections)
• Database configuration management: Managing database settings and schema versions
• Cloud configuration management: Managing configurations for cloud services and resources
• Container configuration management: Managing configurations for containerized applications
• Endpoint device configuration: Managing configurations for endpoint devices like laptops, desktops, and mobile phones
• Monitoring and logging configuration: Managing configurations for monitoring and logging tools
• Backup and recovery configuration: Managing backup policies and configurations
