3.3.4 Set up a Load Balancer

In order to provide scalability and fault tolerance, you will deploy your web front end behind a Lightsail load balancer. Lightsail load balancers handle both HTTP and HTTPS traffic on ports 80 and 443, respectively. For HTTPS, you can request a free certificate from AWS Certificate Manager (ACM) — however, configuring HTTPS connections is out of scope for this lab.

1. From the horizontal menu, click on ‘Networking’.
2. Click on ‘Create load balancer’; then configure:
   • Set ‘Identify your load balancer’ to ‘todo-lb’;
   • Click on ‘Create load balancer’.

Those are the Lightsail resources. Later will migrate from the Lightsail database into an RDS database.
