Key pairs are used to securely connect to EC2 instances: A key pair consists of a public key that AWS stores, and a private key file that you store. Create a file in Bastion and paste the copy content there. Don't over-complicate it. This method allows you to securely connect to Linux instances in private Amazon VPC subnets via a bastion host (aka jump host) that is located in a public subnet. For more information, see Launch an instance in the Amazon EC2 User Guide for Linux Instances. Choose Review and Launch.On the Review Instance Launch page, choose Launch. Secure RDP to EC2 Private Instance Using AWS SSM 1- Prerequisites. A VPN-only subnet with a size /24 CIDR (example: 10.0.0.0/24).

You can SSH into EC2 instances in a private subnet using SSH agent forwarding. Choose an instance type, and then choose Next: Configure Instance Details. Click on SSH and then click on Auth and tick the option allow agent forwarding: Step 6: Connecting an EC2 instance present in the private subnet using a bastion host. Then click the Inbound rules, Click Edit to allow a new inbound rule for EC2 instance.

An EC2 instance with internet connectivity (via NAT gateway) or in a subnet that has VPC endpoints 2- AWS Systems Manager (SSM). Please note that communication using the OS bypass functionality is limited to instances within a single subnet of a Virtual Private Cloud (VPC). These days, a common way of accessing instances in both private and public subnets is through SSM Session Manager. Priority, performance, geographic, weighted round-robin, subnet, and multi-value.
