Using AWS CloudShell: A Handy Alternative to the Terminal

AWS CloudShell is a browser-based terminal available within the AWS Management Console that provides an alternative to using a local terminal for running AWS CLI commands.

What Is AWS CloudShell?

AWS CloudShell is a terminal in the cloud that enables you to run AWS CLI commands directly from your browser. It comes pre-installed with the AWS CLI and other useful tools, allowing you to interact with AWS services seamlessly without additional setup.

Key Characteristics of AWS CloudShell:

1. Pre-Installed AWS CLI:
   • AWS CLI is already set up in CloudShell.
   • Example command: aws --version confirms the installed CLI version (e.g., version 2.1 in the lecture).
2. No Additional Costs: The service is free to use.
3. Automatic Authentication:
   • When you run commands in CloudShell, it uses your AWS account credentials automatically.
   • Default region matches the one you’re logged into via the AWS Management Console.

CloudShell Availability

• Limited to Specific Regions: CloudShell is not available in all AWS regions.
  • To check availability, refer to the CloudShell FAQ in AWS documentation.
  • Choose a supported region for CloudShell if you plan to follow along with hands-on exercises.

Features and Functionalities

1. Persistent File Storage

• CloudShell includes a small amount of persistent storage for your files.
• Example:

The file demo.txt will remain available even if you restart CloudShell.

```bash
echo "test" > demo.txt
```

2. Customizations

• Adjust font size (e.g., small, medium, large).
• Switch between light and dark themes.
