The IaaS Windows server communicates with and collects data from an Amazon EC2 account.

When you use Amazon Web Services for provisioning, DEM workers must meet these configuration requirements.

  • Hosts on which DEMs are installed must have access to the Internet.

    If there is a firewall, HTTPS traffic must be allowed to and from aws.amazon.com, as well as the URLs representing all the EC2 regions your AWS accounts have access to, for example ec2.us-east-1.amazonaws.com for the US East region. Each URL resolves to a range of IP addresses, so you may need to use a tool, such as the one available from the Network Solutions Web site, to list and configure these IP addresses.

  • Internet access from the DEM host is through a proxy server, the DEM service must be running under credentials that can authenticate to the proxy server.
