The AZ-900 introduces you to Azure’s pricing models and the tools available for cost management and optimisation. You’ll learn about using Azure Monitor to track resource performance and gain insights that can lead to significant savings. Understanding how to govern resources with tools like Azure Arc, which extends Azure management to hybrid environments, is also a key skill for controlling expenditure.

What is my security responsibility when using Azure?

Under Azure's Shared Responsibility Model, Microsoft manages the security *of* the cloud (physical data centres, network, hosts), while you are responsible for security *in* the cloud. This includes managing who has access to your resources, configuring network security rules, and encrypting your data.

Are virtual machines the only way to run applications in Azure?

No, virtual machines are just one option. Azure provides a spectrum of compute services, including Azure App Service for web apps and serverless options like Azure Functions. These alternatives can be more cost-effective and require less management, as you don't need to maintain the underlying operating system.
