Accessing the EC2 instance

For an EC2 instance that we have created earlier, the public IP is 54.209.21.209. To ease the connectivity demonstration, I spun up the EC2 server in the public subnet. You should follow the appropriate practice in your environment to get connected to your EC2 instance. Whether to use the bastion server, build IPsec VPN, or use direct connect is something you need to think about, considering your network infrastructure requirement. In order to access the EC2 instance, ensure that you have the OpenSSH module installed in your PowerShell environment. Microsoft announced OpenSSH support on PowerShell in 2015. You can download the OpenSSH from https://github.com/PowerShell/Win32-OpenSSH/releases, and follow the instructions posted on https://github.com/PowerShell/Win32-OpenSSH/wiki/Install-Win32-OpenSSH. This is not the only way that you can get connected...
