This curriculum spans the design and operationalisation of configuration management practices across the software release lifecycle, comparable in scope to a multi-workshop program aligning DevOps, security, and IT operations teams on standardised, auditable configuration workflows.
Module 1: Configuration Management Strategy and Scope Definition
- Define configuration item (CI) ownership across development, operations, and security teams to prevent accountability gaps during audits.
- Select which environments (development, staging, production) require full configuration tracking based on compliance exposure and change frequency.
- Determine whether to track configuration as code or through runtime discovery, weighing consistency against operational overhead.
- Establish naming conventions and tagging standards for CIs to ensure cross-team interoperability in incident and change management.
- Decide whether to include transient infrastructure (e.g., ephemeral containers) in the configuration management database (CMDB), considering monitoring needs versus data bloat.
- Integrate configuration scope decisions with existing ITIL processes, particularly change and incident management, to maintain process alignment.
Module 2: Configuration as Code Implementation
- Choose between declarative (e.g., YAML-based) and imperative (e.g., script-based) configuration models based on team expertise and rollback requirements.
- Implement version control branching strategies for configuration files that mirror application release cycles to prevent configuration drift.
- Enforce code reviews and automated linting for configuration changes to reduce syntax errors and enforce security baselines.
- Embed secrets management (e.g., HashiCorp Vault, AWS Secrets Manager) into configuration templates to avoid hardcoded credentials.
- Design reusable configuration modules with parameterization to support environment-specific deployments without duplication.
- Validate configuration syntax and dependency resolution in pre-commit hooks to catch errors before deployment.
Module 3: Environment Parity and Promotion
- Standardize environment provisioning scripts to ensure consistent middleware versions, network policies, and dependency versions across tiers.
- Implement configuration baselines per environment that allow necessary deviations (e.g., logging verbosity) while minimizing divergence.
- Automate environment comparison reports to detect configuration drift between staging and production after manual fixes.
- Define promotion gates that verify configuration compliance before allowing artifact deployment to higher environments.
- Manage environment-specific overrides through externalized configuration stores (e.g., Spring Cloud Config, Consul) rather than code branching.
- Coordinate configuration freeze periods during release windows to prevent unintended changes from disrupting deployment stability.
Module 4: Integration with CI/CD Pipelines
- Embed configuration validation steps in CI pipelines to reject builds that reference undefined or deprecated CIs.
- Synchronize configuration deployment with application deployment in the pipeline to prevent version mismatches.
- Use pipeline triggers based on configuration changes to initiate dependent service redeployments in microservices architectures.
- Log all configuration changes executed through pipelines in audit-compliant storage with immutable records.
- Implement conditional pipeline stages that skip configuration updates when no relevant changes are detected.
- Isolate configuration deployment failures from application deployment failures to enable targeted remediation.
Module 5: Configuration Drift Detection and Remediation
- Deploy periodic configuration scanning tools (e.g., Puppet, Ansible) to detect unauthorized changes in production systems.
- Classify drift severity based on impact (e.g., security, performance) to prioritize automated versus manual remediation.
- Configure automated remediation jobs with approval workflows for critical systems to prevent unintended outages.
- Integrate drift detection alerts with incident management systems to initiate response protocols.
- Document approved exceptions to baseline configurations to prevent false-positive alerts during audits.
- Balance remediation frequency against system stability, avoiding aggressive auto-correction during peak traffic periods.
Module 6: Security and Compliance Governance
- Map configuration controls to regulatory frameworks (e.g., PCI DSS, HIPAA) to automate compliance reporting.
- Enforce least-privilege access to configuration management tools using role-based access control (RBAC).
- Implement cryptographic signing of configuration artifacts to prevent tampering during transit.
- Conduct regular configuration audits to verify alignment with corporate security baselines and patch policies.
- Integrate vulnerability scanners with configuration data to identify systems running outdated or insecure software versions.
- Restrict direct production configuration changes by requiring all modifications to flow through version-controlled pipelines.
Module 7: Monitoring, Auditing, and Rollback
- Correlate configuration change timestamps with monitoring alerts to identify root causes of performance degradation.
- Store historical configuration states to enable point-in-time restoration during incident investigations.
- Implement rollback procedures that revert both application and configuration changes simultaneously to maintain consistency.
- Tag configuration changes with associated change request IDs for audit trail traceability.
- Use immutable configuration snapshots in production to prevent runtime overrides during troubleshooting.
- Generate monthly configuration audit reports for review by security and compliance stakeholders.
Module 8: Cross-Team Collaboration and Tool Integration
- Align configuration management tooling with incident response workflows to accelerate root cause analysis.
- Integrate CMDB with service catalog systems to ensure accurate service dependency mapping.
- Establish shared SLAs between DevOps and platform teams for configuration change implementation and validation.
- Standardize API contracts between configuration tools and monitoring systems to enable automated health checks.
- Facilitate joint change advisory board (CAB) reviews for high-risk configuration updates involving multiple teams.
- Develop cross-functional playbooks for configuration-related incidents to reduce mean time to resolution (MTTR).
