Separating configuration from code solves these issues. It allows a single build of an application to run seamlessly across distinct environments—development, testing, staging, and production—simply by swapping the underlying config file. 2. Common Configuration File Formats config
Extremely human-readable and widely used for DevOps tools (like Docker and Kubernetes) due to its clean syntax and support for hierarchical data.

When you manage hundreds or thousands of servers, editing config files manually via SSH is impossible. This gave birth to tools. These systems use declarative config files (usually YAML) to define the "desired state" of your infrastructure.
Configures project dependencies, metadata, and scripts for Node.js and Python projects.
