Azure Cloud Shell vs. FastScript vs. PowerShell vs. Shells Comparison Chart

Connect to Azure using an authenticated, browser-based shell experience that’s hosted in the cloud and accessible from virtually anywhere. Azure Cloud Shell is assigned per unique user account and automatically authenticated with each session. Azure Cloud Shell gives you the flexibility of choosing the shell experience that best suits the way you work. Both Bash and PowerShell experiences are available. Microsoft routinely maintains and updates Cloud Shell, which comes equipped with commonly used CLI tools including Linux shell interpreters, PowerShell modules, Azure tools, text editors, source control, build tools, container tools, database tools, and more. Cloud Shell also includes language support for several popular programming languages such as Node.js, .NET, and Python. Use common tools and programming languages in a shell that's updated and maintained by Microsoft.

PowerShell is a cross-platform task automation and configuration management framework, consisting of a command-line shell and scripting language. Unlike most shells, which accept and return text, PowerShell is built on top of the .NET Common Language Runtime (CLR), and accepts and returns .NET objects. This fundamental change brings entirely new tools and methods for automation. Unlike traditional command-line interfaces, PowerShell cmdlets are designed to deal with objects. An object is structured information that is more than just the string of characters appearing on the screen. Command output always carries extra information that you can use if you need it. If you've used text-processing tools to process data in the past, you'll find that they behave differently when used in PowerShell. In most cases, you don't need text-processing tools to extract specific information. You directly access portions of the data using standard PowerShell object syntax.
