Automating with Azure Automation - Ahmed Uzejnović

In this lecture, Ahmed (also known as Arji) engages with members of the PowerShell user group Inn-Salzach, providing insights into PowerShell and Azure Automation, drawing on seven to eight years of experience in IT automation consulting. The session unfolds with a brief introduction to the speaker and the agenda, which outlines a deep dive into Azure Automation, including its pricing, service limits, and practical demonstrations.

The presentation begins with an explanation of Azure Automation as Microsoft's cloud automation framework. Ahmed outlines how it can be used to automate various tasks such as starting and stopping virtual machines, gathering data from SQL servers, and integrating with on-premises resources. He emphasizes the importance of understanding managed identities, which enhance security by allowing Azure resources to authenticate securely without needing credentials hardcoded in scripts.

The speaker then guides the audience through the setup of a demo environment involving the creation of an Azure Automation account and a hybrid worker connected through Azure Arc. Ahmed highlights how managed identities can streamline access to Azure services and discusses the role of automation in optimizing operations. He also demonstrates creating a hybrid worker group that allows for secure automations in an on-premises environment.

Pricing for Azure Automation is touched upon, where Ahmed notes that the first 500 minutes of code execution in a month are free and there are minimal costs beyond that, making it an attractive option for automators. He shares practical examples of runbooks that can automate repetitive tasks, like starting and stopping VMs based on schedules, emphasizing the need for performance optimization in scripting to keep costs down.

The lecture doesn't shy away from challenges; Ahmed draws attention to service limits within Azure Automation, illustrating real-world scenarios where users hit these limits, such as a case with a customer whose complex automation exceeded parameter limits. He advises prospective users to familiarize themselves with these limits to avoid complications during deployment.

As the session progresses, Ahmed moves into a live demo showcasing the Azure portal, demonstrating how to create runbooks, add modules, and utilize source control with GitHub. He shares insights on best practices for managing automation scripts and leveraging Azure Automation's capabilities while highlighting how to effectively troubleshoot potential errors encountered during execution.

In the latter sections, the topic of integrating Azure Key Vault with Azure Automation is introduced, which enhances security by providing access to secrets without hardcoding them into scripts. Ahmed emphasizes the flexibility this provides for developers needing to handle sensitive data securely, particularly in hybrid scenarios.

The presentation culminates with a robust Q&A session where audience members engage with Ahmed, clarifying aspects of managed identities and limitations of Azure Automation. Ahmed wraps up by thanking the participants for their engagement, reinforcing the community aspect of learning and collaboration within the PowerShell user group. This session serves as a comprehensive exploration of Azure Automation and best practices for integrating it into enterprise-level IT operations.
