It is very easy. You just should be aware of each of these elastic load balancers. There are three load balancers. Here's an extract from AWS documentation
"You can select the appropriate load balancer based on your application needs. If you need flexible application management then we recommend you to use Application Load Balancer. If extreme performance and static IP is needed for your application then we recommend you to use Network Load Balancer. If your application is built within the EC2 Classic network then you should use Classic Load Balancer."
Hope this helped!
