Amazon EC2 Instance Connect (EIC) Endpoint, a new feature that allows you to connect securely to your instances and other VPC resources from the Internet. With EIC Endpoint, you no longer need an IGW in your VPC, a public IP address on your resource, a bastion host, or any agent to connect to your resources. EIC Endpoint combines identity-based and network-based access controls, providing the isolation, control, and logging needed to meet your organization’s security requirements.
EIC Endpoint is an identity-aware TCP proxy. It has two modes: first, AWS CLI client is used to create a secure, WebSocket tunnel from your workstation to the endpoint with your AWS Identity and Access Management (IAM) credentials. Once you’ve established a tunnel, you point your preferred client at your loopback address (127.0.0.1 or localhost) and connect as usual. Second, when not using the AWS CLI, the Console gives you secure and seamless access to resources inside your VPC. Authentication and authorization is evaluated before traffic reaches the VPC.
