Using Elastic IP Addresses for Amazon Web Services
Using an elastic IP address allows you to rapidly fail over to another machine in a dynamic
Amazon Web Services cloud environment. In vRealize Automation, the elastic IP address is available to all
business groups that have rights to the region.
An administrator can allocate elastic IP addresses to your Amazon Web Services account by using the
AWS Management Console. There are two groups of elastic IP addresses in any given a region, one range is
allocated for non-Amazon VPC instances and another range is for Amazon VPCs. If you allocate addresses
in a non-Amazon VPC region only, the addresses are not available in an Amazon VPC. The reverse is also
true. If you allocate addresses in an Amazon VPC only, the addresses are not available in a non-
Amazon VPC region.
The elastic IP address is associated with your Amazon Web Services account, not a particular machine, but
only one machine at a time can use the address. The address remains associated with your
Amazon Web Services account until you choose to release it. You can release it to map it to a specic
machine instance.
An IaaS architect can add a custom property to a blueprint to assign an elastic IP address to machines
during provisioning. Machine owners and administrators can view the elastic IP addresses assigned to
machines, and machine owners or administrators with rights to edit machines can assign an elastic IP
addresses after provisioning. However, if the address is already associated to a machine instance, and the
instance is part of the Amazon Virtual Private Cloud deployment, Amazon does not assign the address.
For more information about creating and using Amazon elastic IP addresses, see Amazon Web Services
documentation.
Using Elastic Block Storage for Amazon Web Services
Amazon elastic block storage provides block level storage volumes to use with an Amazon machine instance
and Amazon Virtual Private Cloud. The storage volume can persist past the life of its associated Amazon
machine instance in the Amazon Web Services cloud environment.
When you use an Amazon elastic block storage volume in conjunction with vRealize Automation, the
following caveats apply:
n
You cannot aach 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 aached 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 aached 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 aach 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.
