# Working with the AWS Cloud9 IDE
<a name="ide"></a>

An *integrated development environment (IDE)* provides a set of coding productivity tools such as a source code editor, a debugger, and build tools.

**Important**  
We recommend the following best practices for using your AWS Cloud9:   
Use **source control and backup** your environment frequently. AWS Cloud9 does not perform automatic backups. 
Perform regular **updates of software** on your environment. AWS Cloud9 does not perform automatic software updates. 
 **Turn on AWS CloudTrail** in your AWS account to track activity in your environment. For more information, see [Logging AWS Cloud9 API calls with AWS CloudTrail](cloudtrail.md) 
Only share your environments with **trusted users**. Sharing your environment may put your AWS access credentials at risk. For more information, see [Working with shared environment in AWS Cloud9](share-environment.md)
