What is AWS CloudShell?
AWS CloudShell is a browser-based, pre-authenticated shell that you can launch directly from the AWS Management Console. You can run AWS CLI commands against AWS services using your preferred shell, such as Bash, PowerShell, or Z shell. And, you can do this without needing to download or install command line tools.
When you launch AWS CloudShell, a compute environment that's based on Amazon Linux 2 is created. Within this environment, you can access an extensive range of pre-installed development tools, options for uploading and downloading files, and file storage that persists between sessions.

AWS CloudShell features
AWS Command Line Interface
You can launch AWS CloudShell from the AWS Management Console, and the AWS credentials that you used to sign in to the console are automatically available in a new shell session. This pre-authentication of AWS CloudShell users allows you to skip configuring credentials when interacting with AWS services using AWS CLI version 2. The AWS CLI is pre-installed on the shell's compute environment.
For more information on interacting with AWS services using the command-line interface, see Working with AWS services in AWS CloudShell.
Shells and development tools
With the shell that's created for AWS CloudShell sessions, you can switch seamlessly between your preferred command-line shells. More specifically, you can switch between Bash, PowerShell, and Z shell. You also have access to pre-installed tools and utilities. These include git, make, pip, sudo, tar, tmux, vim, wget, and zip.
The shell environment is pre-configured with support for leading software languages. For example, you can run Node.js and Python projects without needing to first perform runtime installations. PowerShell users can use the .NET Core runtime.
Files that are created in or uploaded to AWS CloudShell can also be committed to a local repository before they're pushed to a remote repository that's managed by AWS CodeCommit.
For more information, see AWS CloudShell compute environment: specifications and software.
Persistent storage
With AWS CloudShell, you can use up to 1 GB of persistent storage for each AWS Region at no
additional cost. Persistent storage is located in your home directory
($HOME) and is private to you. Unlike ephemeral environment resources that
are recycled after each shell session ends, data in your home directory persists between
sessions.
For more information about the retention of data in persistent storage, see Persistent storage.
Security
The AWS CloudShell environment and its users are protected by specific security features such as IAM permissions management, shell session restrictions, and Safe Paste for text input.
Permissions management with IAM
Administrators can grant and deny permissions to AWS CloudShell users using IAM policies. Administrators can also create policies that specify at a granular level the particular actions that those users can perform with the shell environment. For more information, see Managing AWS CloudShell access and usage with IAM policies.
Shell session management
Inactive and long-running sessions are automatically stopped and recycled. For more information, see Shell sessions.
Safe Paste for text input
Enabled by default, Safe Paste is a security feature that asks you to verify that multiline text that you're about to paste into the shell doesn't contain malicious scripts. For more information, see Using Safe Paste for multiline text.
Customization options
You can customize your AWS CloudShell experience by changing screen layouts (multiple tabs), text sizes, and light/dark interface themes. For more information, see Customizing your AWS CloudShell experience.
You can also extend your shell environment by installing your own software and modifying start-up shell scripts.
Session restore
The session restore functionality restores sessions that you were running across single or multiple browser tabs in the CloudShell terminal. If you refresh or reopen recently closed browser tabs, this functionality resumes the session until the shell is stopped because of inactive session. To continue using your CloudShell session, press any key within the terminal window. For more information about Shell sessions, see Shell sessions.
Session restore also restores the latest terminal output and running processes in each terminal tabs.
Session restore isn't available in mobile applications.
Pricing
AWS CloudShell is an AWS service that's available at no additional charge. However, you pay for
other AWS resources that you run with AWS CloudShell. Moreover, standard data transfer rates
