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

When you use Amazon Web Services for provisioning, the servers that host the DEM workers must meet the following 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.
