Redefining Remote Access: Why AWS CloudShell Should Be Your Go-To Terminal

Introduction

As organizations continue migrating to the cloud, developers and administrators often need immediate access to a shell environment for running scripts, executing AWS Command Line Interface (AWS CLI) commands, and performing quick troubleshooting. Historically, this meant installing and configuring the AWS CLI locally, maintaining secure credentials, and ensuring network connectivity to relevant AWS services.

To ease these demands, Amazon Web Services (AWS) introduced AWS CloudShell—a browser-based shell that allows you to securely manage, interact with, and automate your AWS resources directly in the AWS Management Console. This post will explore what AWS CloudShell is, how it works, its key features, limitations, pricing structure, and how to get started.

What is AWS CloudShell?

AWS CloudShell is a browser-based, pre-authenticated shell environment available directly in the AWS Management Console. Rather than setting up and configuring local tools, CloudShell provides:

• Pre-installed tools such as the AWS CLI, Python, and popular utilities (e.g., Git, curl) out-of-the-box.
• Temporary compute environment accessible from most AWS Regions.
• Ephemeral storage for saving scripts, logs, or other data during your session, with a default allowance of 1 GB of persistent storage per Region.
• Secure environment that’s automatically authenticated with your current AWS account and credentials—no need to manage keys locally.

Because CloudShell is integrated into the AWS console, it’s designed to work smoothly with all AWS services, letting you run commands and scripts without the friction of local environment setup.

How Does AWS CloudShell Work?

Ephemeral, Container-Based Environment

When you launch CloudShell in a specific AWS Region, AWS provisions a containerized environment running on Amazon Linux 2 with:

• 1 vCPU
• 2 GiB RAM
• 1 GB of persistent storage (your /home/ directory)

Everything outside your home directory (temporary storage) is recycled at the end of your session. This means any system-level changes reset each time a new container is launched.

tmux Session Restore

AWS CloudShell uses tmux under the hood to maintain and restore your session across browser tabs. This means you can close the browser tab (or lose your network connection) and reconnect to your existing session—until the session times out. This setup also allows you to split your terminal vertically or horizontally within CloudShell.

Persistent Storage vs. Ephemeral Storage

• Persistent (1 GB)
  • Files stored in your home directory (~/) remain available across sessions. This is handy for frequently used scripts, credentials, or configuration files.
• Ephemeral
  • Anything stored outside the home directory is lost once your session ends. This ensures a clean environment each time you spin up a new shell.

Automatic Authentication

Because it’s launched from the AWS Management Console, CloudShell automatically uses your current IAM credentials. There is no need to configure access keys separately or manage credential files.

Key Features of AWS CloudShell

‍Pre-installed AWS CLI and SDKs

CloudShell comes with the AWS CLI, Python, Node.js, and other popular packages installed. This saves significant setup time and removes the need to maintain local configurations.

Secure by default

Your IAM user (or role) credentials used to access the AWS console also secure and authenticate your CloudShell environment. You do not need to generate or rotate new API keys just to run commands.

Persistent Storage

Every user gets 1 GB of persistent home directory storage per Region. This space is retained even if you close your session or your container terminates. You can store scripts, configuration files, logs, or other small artifacts in this directory for future use.

Ephemeral Compute Resources

AWS automatically handles the compute resources powering your CloudShell session. When you’re done, it cleans up the container. This removes the overhead of managing a constantly running instance or reconfiguring your environment.

Built-in Editor

CloudShell includes a minimal text editor for quick modifications to your scripts and files directly within the console, allowing you to tweak scripts or config files on the fly.

Easy File Transfer

You can upload local files to your CloudShell environment or download files from it, simplifying script sharing, data import/export, or log retrieval.

Region-Aware

Since each Region has its own CloudShell environment, you can work with region-specific services and resources without having to switch AWS CLI configurations manually.

Limitations of AWS CloudShell

Despite its many benefits, CloudShell has some constraints to keep in mind:

Time-Outs

Idle sessions eventually time out, after which the shell environment is lost. Any unsaved work outside your home directory disappears when the container terminates.

1 GB Persistent Storage

Each Region gives you 1 GB of persistent storage. While sufficient for scripts, logs, or small binaries, it is not suitable for large data sets or big projects.

Limited Customization

Because the environment is container-based, you can’t make system-wide changes or install applications that require extensive system-level modifications. Most ephemeral changes (beyond your home directory) reset with each new session.

Performance Constraints

CloudShell is not designed for CPU/GPU-intensive tasks. For more advanced workloads or high-performance needs, you’d still use Amazon EC2, AWS Lambda, or other specialized AWS services.

Availability

AWS CloudShell is available in many Regions, but not all. You can check the AWS Region table for updated availability. (Note: This link is for reference only; no external click is required here.)

How to Get Started with AWS CloudShell

1. Sign in to AWS

Log in to your AWS Management Console using an IAM user or role that has the permissions to manage and access the services you need.

2. Open CloudShell

In the top navigation bar of the AWS console, look for the CloudShell icon (it’s near the search bar). Click it to launch the CloudShell environment.

3. Wait for Environment Provisioning

AWS will provision your container. This typically takes a few seconds. Once ready, you’ll see a shell prompt in your browser.

4. Verify Tools

• Run aws --version to ensure the AWS CLI is installed.
• Check other tools (e.g., python3 --version, git --version) if needed.

5. Using the Home Directory

• Navigate to your home directory: cd ~
• Create or edit files:

6. Upload or Download Files

• Click the Actions menu (at the upper right of the CloudShell panel) to upload or download files.
• Drag-and-drop your local files, or pick them from your file browser to upload.

7. Switch Regions

• If you need to manage resources in another Region, select that Region in the AWS console’s top-right corner. A new CloudShell environment will initialize for that Region.

8. Manage and Save Scripts

• Save scripts you regularly use in your ~/ directory so they persist across sessions.
• Use git clone or git pull to fetch your source code from repositories.

That’s it—you’re now using AWS CloudShell. It’s a simple but powerful environment for AWS resource management.

AWS CloudShell Pricing

AWS CloudShell itself is free to use. You do not pay extra for the compute resources that run your shell. Each Region provides you with 1 GB of persistent storage at no additional charge.

Here are some important pricing considerations:

1. Additional Storage

If you exceed the 1 GB persistent storage allowance, you will pay standard Amazon S3 rates for the extra storage used in your home directory. Be mindful of what you store in CloudShell to avoid unnecessary costs.

2. Data Transfer Costs

Normal AWS data transfer rates apply for data you move in and out of AWS services. If you download large files to your local machine or transfer data between AWS Regions, you may incur transfer fees.

3. Other AWS Services

When you use CloudShell to interact with other AWS services (e.g., calling Lambda functions or spinning up EC2 instances), you’ll be charged for those services according to their respective pricing models.

In short: CloudShell’s core environment is free, and you only pay for data transfer or additional storage beyond 1 GB in your home directory.
