AWS Cloud9
User Guide

What Is AWS Cloud9?

AWS Cloud9 contains a collection of tools that you use to code, build, run, test, debug, and release software in the cloud. To work with these tools, you use the AWS Cloud9 integrated development environment, or IDE.

You access the AWS Cloud9 IDE through a web browser. The IDE offers a rich code-editing experience with support for several programming languages and runtime debuggers, as well as a built-in terminal.

You can configure the IDE to your preferences. You can switch color themes, bind shortcut keys, enable programming language-specific syntax coloring and code formatting, and more.

How Does AWS Cloud9 Work?

The following diagram shows a high-level overview of how AWS Cloud9 works.


            Diagram that provides an overview of how AWS Cloud9 works

You use the AWS Cloud9 IDE, running in a web browser on your local computer, to interact with your environment. A cloud compute instance (for example an Amazon EC2 instance) or your own server connects to the environment. An environment is a place where you store your project's files and where you run the tools to develop your apps.

You use the AWS Cloud9 IDE to work with files in the environment. You can:

  • Store these files locally on the instance or server.

  • Clone a remote code repository—such as a repo in AWS CodeCommit—into your environment.

  • Work with a combination of local and cloned files in the environment.

In the background, you can instruct AWS Cloud9 to have Amazon EC2 create an Amazon EC2 instance and then connect the environment to the newly-created instance. We call this type of setup an EC2 environment. You can also instruct AWS Cloud9 to connect an environment to an existing cloud compute instance or your own server. We call this type of setup an SSH environment.

Here are the key similarities and differences between EC2 environments and SSH environments.

EC2 environments SSH environments

AWS Cloud9 creates an associated Amazon EC2 instance and manages that instance's lifecycle (for example, start, stop, and terminate).

You use an existing cloud compute instance or your own server. You manage that instance's or server's lifecycle.

The instance runs on Amazon Linux.

You can use any cloud compute instance that runs Linux, or your own server running Linux.

AWS Cloud9 automatically sets up the instance to start working with AWS Cloud9.

You must manually configure the instance or your own server to work with AWS Cloud9.

AWS Cloud9 automatically sets up the AWS Command Line Interface (AWS CLI) on the instance for you to start using.

If you want to use the AWS CLI on the instance or your own server, you must set it up yourself.

The instance has access to hundreds of useful packages, with some common packages already installed and configured, such as Git, Docker, Node.js, and Python.

You might need to download, install, and configure additional packages to complete common tasks.

You maintain the instance, for example by periodically applying system updates.

You maintain the instance or your own server.

When you delete the environment, AWS Cloud9 automatically terminates the associated instance.

When you delete the environment, the instance or your own server remains.

You can create and switch between multiple environments, with each environment set up for a specific development project. By storing the environment in the cloud, your projects no longer need to be tied to a single computer or server setup. This enables you to do things such as easily switch between computers and more quickly onboard developers to your team.

About Cloud9 Versions

There are currently two versions of Cloud9 available: c9.io and AWS Cloud9. This AWS Cloud9 User Guide only covers AWS Cloud9.

c9.io is available only to existing c9.io users. For more information, see Cloud9 now runs on and integrates with AWS on the c9.io website.

c9.io and AWS Cloud9 are not interoperable. You can't use an account or workspace in c9.io with an account or environment in AWS Cloud9.
