State data collection occurs automatically every 15 minutes by default. It gathers information about the state
of managed instances, which are instances that vRealize Automation creates. The following are examples of
state data:
n
Windows passwords
n
State of machines in load balancers
n
Elastic IP addresses
A fabric administrator can initiate inventory and state data collection and disable or change the frequency of
inventory and state data collection.
Using Amazon Virtual Private Cloud
Amazon Virtual Private Cloud allows you to provision Amazon machine instances in a private section of the
Amazon Web Services cloud.
Amazon Web Services users can use Amazon VPC to design a virtual network topology according to your
specications. You can assign an Amazon VPC in vRealize Automation. However, vRealize Automation
does not track the cost of using the Amazon VPC.
When you provision using Amazon VPC, vRealize Automation expects there to be a VPC subnet from
which Amazon obtains a primary IP address. This address is static until the instance is terminated. You can
also use the elastic IP pool to also aach an elastic IP address to an instance in vRealize Automation. That
would allow the user to keep the same IP if they are continually provisioning and tearing down an instance
in Amazon Web Services.
Use the AWS Management Console to create the following elements:
n
An Amazon VPC, which includes Internet gateways, routing table, security groups and subnets, and
available IP addresses.
n
An Amazon Virtual Private Network if users need to log in to Amazon machines instances outside of
the AWS Management Console.
vRealize Automation users can perform the following tasks when working with an Amazon VPC:
n
A fabric administrator can assign an Amazon VPC to a cloud reservation. See “Create an Amazon
Reservation,” on page 194.
n
A machine owner can assign an Amazon machine instance to an Amazon VPC.
For more information about creating an Amazon VPC, see Amazon Web Services documentation.
Using Elastic Load Balancers for Amazon Web Services
Elastic load balancers distribute incoming application trac across Amazon Web Services instances.
Amazon load balancing enables improved fault tolerance and performance.
Amazon makes elastic load balancing available for machines provisioned using Amazon EC2 blueprints.
The elastic load balancer must be available in the Amazon Web Services, Amazon Virtual Private Network
and at the provisioning location. For example, if a load balancer is available in us-east1c and a machine
location is us-east1b, the machine cannot use the available load balancer.
vRealize Automation does not create, manage, or monitor the elastic load balancers.
For information about creating Amazon elastic load balancers by using the
Amazon Web Services Management Console, see Amazon Web Services documentation.
