Class LoadBalancer

java.lang.Object
  org.jclouds.elb.domain.LoadBalancer

public class LoadBalancer
extends Object

A load balancer is represented by a DNS name and a set of ports. The load balancer is the destination to which all requests intended for your application should be directed. Each load balancer can distribute requests to multiple EC2 instances. Load Balancers can span multiple Availability Zones within an EC2 region, but they cannot span multiple regions.

note

Elastic Load Balancing automatically generates a DNS name for each load balancer. You can map any other domain name (such as www.example.com) to the automatically generated DNS name using CNAME. Or you can use an Amazon Route 53 alias for the load balancer's DNS name. Amazon Route 53 provides secure and reliable routing to the infrastructure that uses AWS products, such as Amazon EC2, Amazon Simple Storage Service (Amazon S3), or Elastic Load Balancing. For more information on using Amazon Route 53 for your load balancer, see Using Domain Names with Elastic Load Balancing. For information about CNAME records, see the CNAME Record Wikipedia article.
