AWS Setup

The server is an EC2 instance with ELB at AWS. Essential setup is listed as below:

• EC2 instance with Ubuntu 14.04 LTS. EBS drive is mount to /dev/sda1.
• Use the following Security Groups: HTTP & SSH (opens port 80 and port 22), HTTPS (opens port 443).
• Submit SSL Certificate through aws iam. See here. Use the SSL Certificate for 443 forwarding protocol.
• Add instance to ELB, configure with port forwarding 80 to 80, 443 to 443. Use same Security Groups as EC2.
• Set ELB Health Check to address HTTPS:443/ping_test/, with interval 180 s and timeout 15 s.

Once done, you can access the server via ssh. Use the server's Public IP address, instead of Private IP. AWS EC2 are configured to use a certificate for authentication, not password (In fact, user ubuntu has no password). Use -i to supply the certificate.
