Azure Automation State Configuration is an Azure-hosted service that allows you to write, manage and compile Powershell Desired State Configuration (DSC) configurations, import DSC Resources, and assign configurations to target nodes, all in the cloud.
Azure Automation State Configuration is highly scalable and adaptable, and it’s capable of managing and monitoring 1000s of nodes. It allows for the automation of deployment, configuration, management, and monitoring across both physical and virtual machines, irrespective of where they are located: on-premises, Azure, or with another cloud provider.
Key Features
- Platform-agnostic: Azure Automation DSC doesn’t only manage Windows environments. It also supports any platform that can run PowerShell 4.0 or newer, which includes a variety of Linux distributions.
- Continuous Monitoring: The reporting capabilities of Azure Automation DSC enable you to track changes across your environment and detect drifts from a desired state.
- Integration with Azure and Third-Party Services: Use Azure Monitor, Azure Security Center, and Azure Update Management for a comprehensive configuration management solution.
Using Azure Automation State Configuration
To utilize Azure Automation State Configuration, a DSC configuration file is created and compiled into a MOF file (Managed Object Format). These MOF files are then assigned to the target nodes by Azure Automation DSC.
Below is a basic example of a configuration script that could be used to install IIS on a server:
Configuration InstallIIS
{
Import-DscResource –ModuleName PSDesiredStateConfiguration
Node “localhost”
{
WindowsFeature IIS
{
Ensure = “Present”
Name = “Web-Server”
}
}
}
This script uses the WindowsFeature DSC Resource to ensure that the Web-Server feature (which is IIS) is present on the server.
Conclusion
When implementing Microsoft DevOps solutions, Azure Automation State Configuration provides a comprehensive configuration management system to ensure your environments are maintained at the desired state and streamlined across multiple platforms.
In preparing for the AZ-400 Designing and Implementing Microsoft DevOps Solutions exam, it is crucial to understand how Azure Automation State Configuration fits in the broader DevOps strategy. This includes how it integrates with other Azure services and how to create and assign DSC configurations. This hands-on interaction will provide the confidence and knowledge to answer any related questions on the exam.
Just remember: The goal of DevOps, and thus configuration management, is to streamline operations and reduce errors. With Azure Automation State Configuration, you have a tool that can help you accomplish this goal.
