The instance I choose was the following:
Basic 64-bit Microsoft Windows Server 2008 (AMI Id: ami-d9e40db0) Microsoft Windows 2008 R1 SP2 Datacenter edition and 64-bit architecture.
I have installed Tomcat + an application and AM able to see the website when I access the local IP thru IE (in the EC2 instance).
However, when I try accessing it as:
* the assigned Elastic IP * the ec2-999-999-999-999.compute-1.amazonaws.com
from the EC2 instance itself or from outside, it doesn't work. IE says: Internet Explorer cannot display the webpage
* disabling the Firewall -> no luck * waiting for a bit -> no luck
I can't ping the machine assigned Elastic IP either.
The allowed connections (as seen in Amazon's Management Console) is as:
Connection Method Protocol From Port To Port Source (IP or group) SSH tcp 22 22 0.0.0.0/0 RDP tcp 3389 3389 0.0.0.0/0 DNS tcp 53 53 0.0.0.0/0 DNS udp 53 53 0.0.0.0/0 HTTP tcp 80 80 0.0.0.0/0
