AWS CLI vs. AWS CloudShell: Choosing the Right Command-Line Interface

AWS CLI vs. AWS CloudShell: Amazon Web Services (AWS) provides developers and administrators with a variety of tools to interact with and manage their cloud resources. Two popular choices are the AWS Command-Line Interface (CLI) and AWS CloudShell. In this article, we’ll compare AWS CLI and AWS CloudShell, providing a comprehensive comparison table, exploring their features, use cases, best practices, frequently asked questions, and sharing external resources to help you make an informed decision on the right command-line interface for your AWS management needs.

Understanding AWS CLI and AWS CloudShell

Before we dive into the comparison, let’s clarify what AWS CLI and AWS CloudShell are:

  • AWS CLI: The AWS Command-Line Interface is a set of open-source tools that allow you to interact with AWS services using commands in your terminal. It provides powerful and flexible control over your AWS resources and services.
  • AWS CloudShell: AWS CloudShell is a browser-based, interactive shell environment provided within the AWS Management Console. It includes a preconfigured AWS CLI and additional tools for managing AWS resources directly from your web browser.


Comparison Table: AWS CLI vs. AWS CloudShell

To help you understand the differences between AWS CLI and AWS CloudShell, we’ll provide a comparison table that highlights their key attributes:

Parameter AWS CLI AWS CloudShell
Accessibility Requires installation on your local machine. Available directly in the AWS Management Console, accessible from a web browser.
Platform Compatibility Works on Windows, macOS, and Linux. Works on any platform with a modern web browser.
Setup and Configuration Requires installation and credential configuration. No installation or configuration required; uses IAM role.
Usage Flexibility Offers a wide range of command-line options and scripting capabilities. Supports AWS CLI commands with some limitations.
Storage and Data Transfer Uses local storage for scripts and data. Data and scripts are stored in an S3 bucket.
Integration with Other Tools Integrates easily with local scripts and third-party tools. Limited integration capabilities compared to local CLI.
Resource Management Requires explicit AWS configuration and credentials management. Seamlessly manages AWS resources using IAM roles.
Cost Management Users must manage and monitor costs manually. Simplifies cost management with no additional cost.
Resource Isolation Resource isolation is determined by local configuration. Users operate in a managed, isolated environment.

Key Features


  1. Local Installation: AWS CLI can be installed locally, allowing you to work offline and utilize custom scripts.
  2. Extensive Configuration: It offers advanced configuration options for managing credentials and profiles.
  3. Powerful Scripting: Ideal for creating and automating complex scripts for AWS resource management.
  4. Integration: Supports integration with third-party tools and local applications.

AWS CloudShell:

  1. Web-Based: Accessible directly from the AWS Management Console, eliminating the need for local installation.
  2. Seamless Authentication: Utilizes AWS Identity and Access Management (IAM) roles for authentication.
  3. Persistent Storage: Stores data and scripts in an S3 bucket, ensuring continuity between sessions.
  4. Resource Isolation: Provides a managed, isolated environment for secure operations.

Use Cases


  1. Advanced scripting and automation.
  2. Resource management on local machines.
  3. Custom integration with local tools and applications.

AWS CloudShell:

  1. Quick and convenient resource management from the AWS Management Console.
  2. Training and learning AWS CLI without local installation.
  3. Isolated, controlled environment for secure operations.


Best Practices


  1. Keep credentials secure and rotate them regularly.
  2. Implement a proper IAM policy for the AWS CLI user.
  3. Utilize AWS CLI profiles for multiple AWS accounts.

AWS CloudShell:

  1. Leverage IAM roles for seamless authentication.
  2. Use S3 buckets for data and script storage.
  3. Monitor S3 storage to avoid unnecessary costs.

Frequently Asked Questions (FAQs)

Q1: Can I use AWS CLI and AWS CloudShell simultaneously?

Yes, you can use both AWS CLI and AWS CloudShell based on your specific needs. They can complement each other for different scenarios.

Q2: Are there any additional costs associated with AWS CloudShell?

No, AWS CloudShell is available at no extra cost, but standard AWS service charges may apply for the use of AWS resources.

Q3: Can I access my local AWS CLI configuration from AWS CloudShell?

No, AWS CloudShell operates in an isolated environment, separate from your local AWS CLI configuration.

Q4: How do I manage IAM roles in AWS CloudShell?

You can assign IAM roles to your AWS CloudShell session, and the environment will inherit the permissions associated with those roles.

Q5: Does AWS CloudShell support custom scripts and tools?

AWS CloudShell primarily supports AWS CLI commands and scripting. While it offers some storage, it may not support all the custom scripts and tools you use locally with AWS CLI.

Q6: Can I use AWS CloudShell for production-level operations?

AWS CloudShell is designed for resource management and learning, but it may not be suitable for production-level operations, which often require custom scripts and extensive tool integrations.
