Adds the specified instances to the specified load balancer.
The instance must be a running instance in the same network as the load balancer (EC2-Classic or the same VPC). If you have EC2-Classic instances and a load balancer in a VPC with ClassicLink enabled, you can link the EC2-Classic instances to that VPC and then register the linked EC2-Classic instances with the load balancer in the VPC.
Note that RegisterInstanceWithLoadBalancer
completes when the request has been
registered. Instance registration takes a little time to complete. To check the state
of the registered instances, use DescribeLoadBalancers or DescribeInstanceHealth.
After the instance is registered, it starts receiving traffic and requests from the
load balancer. Any instance that is not in one of the Availability Zones registered
for the load balancer is moved to the OutOfService
state. If an Availability
Zone is added to the load balancer later, any instances registered with the load balancer
move to the InService
state.
To deregister instances from a load balancer, use DeregisterInstancesFromLoadBalancer.
For more information, see Register or De-Register EC2 Instances in the Classic Load Balancers Guide.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginRegisterInstancesWithLoadBalancer and EndRegisterInstancesWithLoadBalancer.
