Enable AWS Systems Manager for all EC2 instances in an account

Recently, on Feb 17, 2023 AWS have released new feature which will enable customers to on-board all EC2 instances in account with AWS System Manager, that too with minimum configuration. Isn’t it great!!

Did you Know?

Any instance/ node which is configured for AWS System Manager is called as Managed Instance/ Managed Node. Whether it is AWS EC2 instance, Azure VM (Hybrid Environment) or On-Premise Server.

Earlier if any EC2 instance was require to be configured as Managed Instance then an IAM instance profile/ custom role was needed to be attached with every EC2 Instance manually. This could get cumbersome if there are EC2 instances to be managed at the scale.

This scalability is possible with new feature called as Default Host Management Configuration (DHMC) agent. DHMC simplifies the experience of managing EC2 instances by attaching permissions at the account level

You can begin utilizing the benefits of DHMC in just a few clicks from the Fleet Manager console. This feature ensure Patch Manager, Session Manager, and Inventory are available for all new and existing instances in an account.



  1. In order to leverage benefit of Default Host Management Configuration feature, you need to ensure all instances with Instance Metadata Service Version 2 (IMDSv2) in your account  should have SSM Agent version 3.2.582.0 or later.
  2. Default Host Management Configuration doesn’t support Instance Metadata Service Version 1.
  3. You need to attach IAM instance role at System Manager level, System Manager assume role by calling EC2 services.
  4. You must turn ON the Default Host Management Configuration setting in each Region you wish to automatically manage your Amazon EC2 instances.

In this short video I will demonstrate how to use this new feature.

Azure Automation Visual Studio Code Extension

During January 2023 Microsoft had launched Preview of Visual Studio Code Extension for Azure Automation. Azure Automation is one of the commonly used Azure service, which is used to automate mundane activities by IT Professional.

Azure Automation provides a new extension from VS Code to create and manage runbooks. Using this extension, you can perform all runbook management operations such as, creating and editing runbooks, triggering a job, tracking recent jobs output, linking a schedule, asset management, and local debugging.


  • No need to go to Azure Portal for Managing Runbook
  • Improve overall E2E time for support
  • Local Debugging – Yes you can debug your runbook locally, this was headache for Support Engineers since there was no provision for debugging script from Azure Portal (Except relying on output stream). Though this is feature is still in preview but will definitely be helpful in future.
Limitations as of writing this blog (Feb 2023)
  • Creation of new schedules.
  • Adding new Certificates in Assets.
  • Upload Modules (PowerShell and Python) packages from the extension.
  • Auto-sync of local runbooks to Azure Automation account. You will have to perform the operation to Fetch or Publish runbook.
  • Management of Hybrid worker groups.
  • Graphical runbook and workflows.
  • For Python, we don’t provide any debug options. We recommend that you install any debugger extension in your Python script.
  • Currently, we support only the unencrypted assets in local run.
