Azure Automation + Runbooks


Intro

Azure Automation delivers a cloud-based automation and configuration service that supports consistent management across your Azure and non-Azure environments. It comprises process automation, configuration management, update management, shared capabilities, and heterogeneous features.

Tips and Tidbits

 

  • You need to create an automation account first.

    • Automation account names are unique per region and resource group.

    • Names for Automation accounts that have been deleted might not be immediately available.

    • The name can contain only letters, numbers, and hyphens. The name must start with a letter, and it must end with a letter or a number. The account name length must be from 6 to 50 characters

  • When you start Azure Automation for the first time, you must create at least one Automation account.

    • Automation accounts allow you to isolate your Automation resources, runbooks, assets, and configurations from the resources of other accounts

  • Azure Automation allows you to automate frequent, time-consuming, and error-prone cloud management tasks by using PowerShell, PowerShell Workflow, and graphical runbooks

  • Automation executes your runbooks based on the logic defined inside them.

  • If a runbook is interrupted, it restarts at the beginning. This behavior requires you to write runbooks that support being restarted if transient issues occur.

  • Each job accesses Azure resources by making a connection to your Azure subscription.

  • The job can only access resources in your data center if those resources are accessible from the public cloud.

  • You can't convert runbooks from graphical to text type, or the other way around

 

 

  • Run As accounts in Azure Automation provide authentication for managing resources using Automation runbooks and other Automation features. 

  • When you create a Run As account, it performs the following tasks:

    • Creates an Azure AD application with a self-signed certificate, creates a service principal account for the application in Azure AD, and assigns the Contributor role for the account in your current subscription

Where to run runbooks

  • Runbooks in Azure Automation can run on either an Azure sandbox or a Hybrid Runbook Worker.

  • When runbooks are designed to authenticate and run against resources in Azure, they run in an Azure sandbox, which is a shared environment that multiple jobs can use.

  • Jobs using the same sandbox are bound by the resource limitations of the sandbox.

  • You can use a Hybrid Runbook Worker to run runbooks directly on the computer that hosts the role and against local resources in the environment. 

  • Automation sandboxes support .NET Framework 4.7.2, and upgrading to a different version is not supported.

  • The Azure sandbox environment does not support interactive operations.

    • It prevents access to all out-of-process COM servers, and it does not support making WMI calls to the Win32 provider in your runbook. 

  • If you need to create temporary files as part of your runbook logic, you can use the Temp folder (that is, $env:TEMP) in the Azure sandbox for runbooks running in Azure. The only limitation is you cannot use more than 1 GB of disk space, which is the quota for each sandbox
