F5 CloudFormation templates on Github
-------------------------------------

Open a new tab in the web browser. Click on the "PC101 AS3 Template" URL bookmark in the bookmark toolbar. An AS3 Declaration is a single JSON-formatted file that defines your virtual server(s) and all accompanying configuration objects. Some interesting configuration objects are highlighted in the screenshot below:

  - You use AWS tags to lookup the application pool members dynamically. You do not hardcode the IP addresses of pool members.
  - An HTTP/2 profile is enabled.
  - The Virtual Server Address is a "catch-all" wildcard address: 0.0.0.0/0.
