Using Elastic Load Balancers for Amazon Web Services
Elastic load balancers distribute incoming application traffic 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.
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 specific
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.
