Treating infrastructure configuration as code is a fundamental DevOps principle, and it starts with placing all configuration files under version control. Subversion (SVN) provides a centralized repository for tracking changes to server configurations, scripts, and deployment artifacts with full audit history.
Organizing Your Configuration Repository
Create a structured SVN repository with directories for each server role or service. A common layout includes top-level directories for web servers, database servers, monitoring, and shared libraries. Each configuration file is checked in with a meaningful commit message explaining why the change was made, creating an audit trail that is invaluable during incident investigation.
Use SVN hooks to trigger automated validation when configurations are committed. A pre-commit hook can run syntax checks on Apache configs, validate JSON or YAML files, and enforce naming conventions. Post-commit hooks can trigger deployment scripts that automatically push updated configurations to the relevant servers.
While newer distributed version control systems like Git are gaining popularity, SVN's centralized model has advantages for configuration management. There is a single source of truth, access controls are straightforward, and the linear revision numbering makes it easy to reference specific configuration states. Integrate SVN with your change management process so that every configuration change is linked to an approved change request.
