n
No rewalls between DEM host and the Windows server, or ports opened as described in “vRealize
Automation Port Requirements,” on page 26.
Servers that host DEM Worker instances might have additional requirements depending on the provisioning
resources that they interact with.
Amazon Web Services EC2 Requirements
A vRealize Automation IaaS Windows server communicates with and collects data from an Amazon EC2
account.
When you use Amazon Web Services (AWS) for provisioning, the IaaS Windows servers that host the DEM
workers must meet the following requirements.
n
DEM worker hosts must have Internet access.
n
If the DEM worker hosts are behind a rewall, HTTPS trac must be allowed to and from
aws.amazon.com as well as the URLs for EC2 regions that your AWS accounts have access to, such as
ec2.us-east-1.amazonaws.com for the US East region.
Each URL resolves to a range of IP addresses, so you might need to use a tool, such as the one available
from the Network Solutions Web site, to list and congure these IP addresses.
n
If the DEM worker hosts reach the Internet through a proxy server, the DEM service must be running
under credentials that can authenticate to the proxy server.
