Summary
This module described Desired State Configuration (DSC) and its components for implementation with Azure Automation. You learned how to manage configuration drift, create DSC configurations, implement DSC for Linux environments, and plan for hybrid management.
Learning objectives summary
You learned how to:
- Understand configuration drift: Identify how infrastructure configurations change over time, the concept of snowflake configurations, and the security implications of configuration drift.
- Implement Desired State Configuration (DSC): Use PowerShell DSC with configurations, resources, and Local Configuration Manager (LCM) to define and enforce desired states.
- Describe Azure Automation State Configuration: Use Azure Automation as a centralized DSC pull server with built-in management, compilation, and monitoring capabilities.
- Create DSC configuration files: Write PowerShell scripts with configuration blocks, node blocks, and resource blocks to define infrastructure state.
- Implement DSC for Linux: Apply DSC to Linux environments on Azure using DSC for Linux resources and Azure Automation State Configuration.
- Plan for hybrid management: Manage both Azure and on-premises resources with DSC for consistent configuration across hybrid environments.
