Top 10 Questions for Microsoft AZ-104 certification exam?

What is the difference between a virtual machine and a cloud service in Azure?

In Azure, a virtual machine (VM) is an emulation of a computer system, which allows you to run an operating system and associated applications in a virtual environment. You have full control over the VM, including the operating system, applications, and networking settings.

On the other hand, a cloud service in Azure provides a platform for deploying and managing web applications in the cloud. It is a fully managed platform that abstracts away the underlying infrastructure, allowing you to focus on your application code.

While a virtual machine gives you complete control over the operating system and applications, a cloud service is a more streamlined platform that is easier to manage and scale. Additionally, virtual machines can be used for a wider range of applications and scenarios, while cloud services are primarily designed for web applications.
