![]() However, until now EC2 Instance Connect required a public IP address on your instance when connecting over the Internet. First is EC2 Instance Connect, which provides a mechanism that uses IAM credentials to push ephemeral SSH keys to an instance, making long-lived keys unnecessary. Prior to the launch of EIC Endpoints, AWS offered two key services to help manage access from public address space into a VPC more carefully. And finally, IAM and Security Groups can be used to control access, which we discuss in more detail in the next section. ![]() Third, they preserve existing workflows, enabling you to continue using your preferred client software on your local workstation to connect and manage your resources. Second, no agent is needed on the resource you wish to connect to, allowing for easy remote administration of resources which may not support agents, like third-party appliances. First, they don’t require your VPC to have direct Internet connectivity using an IGW or NAT Gateway. ![]() User connecting to private EC2 instances through an EIC EndpointĮIC Endpoints provide a high degree of flexibility. The following figure shows an illustration of a user connecting via an EIC Endpoint:įigure 1. Authentication and authorization is evaluated before traffic reaches the VPC. Second, when not using the AWS CLI, the Console gives you secure and seamless access to resources inside your VPC. 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. 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. EIC Endpoint product overviewĮIC Endpoint is an identity-aware TCP proxy. In this post, we provide an overview of how the EIC Endpoint works and its security controls, guide you through your first EIC Endpoint creation, and demonstrate how to SSH to an instance from the Internet over the EIC Endpoint. Furthermore, it gives you the flexibility to continue using your favorite tools, such as PuTTY and OpenSSH. EIC Endpoint works with the AWS Management Console and AWS Command Line Interface (AWS CLI). As a bonus, your organization administrator is also relieved of the operational overhead of maintaining and patching bastion hosts for connectivity. EIC Endpoint combines identity-based and network-based access controls, providing the isolation, control, and logging needed to meet your organization’s security requirements. 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. Today we launched 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. Typically, you’d first have to connect to a bastion host with a public IP address that your administrator set up over an Internet Gateway (IGW) in your VPC, and then use port forwarding to reach your destination. Imagine trying to connect to an Amazon Elastic Compute Cloud (Amazon EC2 ) instance within your Amazon Virtual Private Cloud (Amazon VPC) over the Internet.
