When you use an Amazon elastic block storage volume in conjunction with vRealize Automation, the
following caveats apply:
n
You cannot attach an existing elastic block storage volume when you provision a machine instance.
However, if you create a new volume and request more than one machine at a time, the volume is
created and attached to each instance. For example, if you create one volume named volume_1 and
request three machines, a volume is created for each machine. Three volumes named volume_1 are
created and attached to each machine. Each volume has a unique volume ID. Each volume is the
same size and in the same location.
n
The volume must be of the same operating system and in the same location as the machine to which
you attach it.
n
vRealize Automation does not manage the primary volume of an elastic block storage-backed
instance.
For more information about Amazon elastic block storage, and details on how to enable it by using
Amazon Web Services Management Console, see Amazon Web Services documentation.
Scenario: Configure Network-to-Amazon VPC Connectivity for a Proof of
Concept Environment
As the IT professional setting up a proof of concept environment to evaluate vRealize Automation, you
want to temporarily configure network-to-Amazon VPC connectivity to support the vRealize Automation
Software feature.
Network-to-Amazon VPC connectivity is only required if you want to use the guest agent to customize
provisioned machines, or if you want to include Software components in your blueprints. For a production
environment, you would configure this connectivity officially through Amazon Web Services, but because
you are working in a proof of concept environment, you want to create temporary network-to-Amazon
VPC connectivity. You establish the SSH tunnel and then configure an Amazon reservation in
vRealize Automation to route through your tunnel.
Prerequisites
n
Install and fully configure vRealize Automation. See Installing and Configuring vRealize Automation
for the Rainpole Scenario.
n
Create an Amazon AWS security group called TunnelGroup and configure it to allow access on port
22.
n
Create or identify a CentOS machine in your Amazon AWS TunnelGroup security group and note the
following configurations:
n
Administrative user credentials, for example root.
n
Public IP address.
n
Private IP address.
n
Create or identify a CentOS machine on the same local network as your vRealize Automation
installation.
