A company must manage Amazon EC2 instances for both Linux and Windows hosts using command line interfaces in an environment without internet access. They need to implement role-based access control for instance management and operate within a standalone on-premises setup. Which solution meets these requirements with the minimal maintenance effort?
A
Set up an AWS Direct Connect connection between the on-premises environment and the VPC where the instances are deployed. Configure routing, security groups, and ACLs. Connect to the instances by using the Direct Connect connection.
B
Deploy and configure AWS Systems Manager Agent (SSM Agent) on each instance. Deploy VPC endpoints for Systems Manager Session Manager. Connect to the instances by using Session Manager.
C
Establish an AWS Site-to-Site VPN connection between the on-premises environment and the VPC where the instances are deployed. Configure routing, security groups, and ACLs. Connect to the instances by using the Site-to-Site VPN connection.
D
Deploy an appliance to the VPC where the instances are deployed. Assign a public IP address to the appliance. Configure security groups and ACLs. Connect to the instances by using the appliance as an intermediary.
