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.

You use the IDE to interact with an AWS Cloud9 development environment. An environment is a place where you store your project's files and where you run the tools to develop your apps. In the background, you can instruct AWS Cloud9 to have Amazon EC2 launch an Amazon EC2 instance and then connect the environment to the newly-launched instance. We call this type of setup an EC2 environment. You can also instruct AWS Cloud9 to connect an environment to an existing Amazon EC2 instance or your own server. We call this type of setup an SSH environment.

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.

            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. 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.
