Getting Started with Elastic Load Balancing

You do not install your ACM Certificate directly on the Amazon EC2 instances that contain your website or your application. Instead, you associate the ACM Certificate with an AWS service, such as Elastic Load Balancing. Elastic Load Balancing improves the availability of your website or application by automatically distributing incoming traffic across your Amazon EC2 instances. The load balancer serves as a single point of contact for clients. This is shown by the following illustration.

You must perform the following steps to use ACM with a load balancer.

  1. Install a website or application on one or more Amazon EC2 instances.

  2. Create an Elastic Load Balancing load balancer to route client traffic to the Amazon EC2 instances.

  3. Use the ACM console, API, or AWS Command Line Interface to request an ACM Certificate or import a certificate into ACM.

  4. Use the Elastic Load Balancing console, API, or AWS CLI to provision the ACM Certificate on the load balancer.

  5. Clients access the website through the load balancer.

  6. The load balancer distributes client traffic to the Amazon EC2 instances.
