AWS Cloud9 releases enhanced VPC support

[AWS Cloud9](/cloud9/) is a cloud-based integrated development environment (IDE) that lets you write, run, and debug your code with just a browser. Cloud9 is excited to offer enhanced VPC support for customers using the Cloud9 IDE. This release adds support for creating Cloud9 environments in a private subnet with no ingress and optionally no egress. Prior to this release, Cloud9 environments had to have a public IP address and the SSH port configured to be accessible from AWS Cloud9\. Today we have reinforced our security posture by no longer requiring inbound connections to Cloud9 environments. This new feature leverages [AWS Systems Manager](/systems-manager/) (SSM) to eliminate the need for SSH connections. Customers can enable Cloud9 private subnet support using the AWS Management Console, AWS CloudFormation, or the AWS SDK. To get started, please see the [full documentation here](https://docs.aws.amazon.com/cloud9/latest/user-guide/ec2-ssm.html).
