BEFORE PROCEEDING with a instance:
  • The administrator of your domain (usually someone in your IT department) will need to create a DNS record that maps to the public hostname you previously selected to the elastic IP address you just created.
  • Make sure that your public hostname resolves to the elastic IP address created above. You can use an online service to check, for example:
  1. Go to your EC2 Dashboard
  2. In the left navigation bar, open the Network and Security section
  3. Select Elastic IPs
  4. Select the desired IP address from the list
  5. Click on the Actions button and select Associate Address
  6. Select the desired running instance for the Instance field
  7. Click on the Associate button
