Telnet to a cloud instance from outside

Question

I have a cloud MS window instance on EC2. I want to telnet this instance from my own machine (outside).

What I did: 1- turned off the MS firewall 2- turned on the telnet client and telnet service in the instance..

Now from my machine, if the public ip address for the cloud instance is 80.8.8.9. then, on the the cmd terminal from outside. I wrote telnet 80.8.8.9 where It said that the connection is failed.

What I am missing, what is the wrong thing I did..

确保您转到AWS management console/EC2/Security Groups/[Your Security Group]/Inbound然后打开到您自己的计算机网络的telnet端口（23）。
