create a public internet-facing load balancer and attach backend Amazon EC2 instances that are not publicly reachable

Question

I want to create a public internet-facing load balancer and attach backend Amazon EC2 instances that are not publicly reachable.

Answer 1

Follow these steps:

1. List the Availability Zones that have the instances you want to attach to the load balancer.
2. Create an equal number of public subnets in the same Availability Zones where your private instances exist.
3. From the Amazon EC2 console, create a load balancer and associate the newly created public subnets with it. For instructions, see Step 1: Select a Load Balancer Type and Step 2: Define your Load Balancer.
4. Add the private instances to the load balancer; for instructions, see Step 5: Register EC2 Instances with Your Load Balancer.
