Creating ELB target groups

In this recipe, we will learn how to create an Elastic Load Balancer (ELB) target group. The application load balancer and network load balancer route traffic to ELB target groups, unlike classic load balancers, which route traffic to individual EC2 instances.

Getting ready

To follow this recipe, we need the following:

• A working AWS account, awsseccb-sandbox-1, and a user awsseccbadmin1, as described in the Technical requirements section.
• A VPC, awsseccb-vpc, following the Setting up VPC plus VPC resources with minimal efforts recipe from Chapter 5.
• Two EC2 instances in the aforementioned awsseccb-vpc VPC, following the Launching an EC2 instance with a web server using user data recipe in Chapter 5, with the following exceptions. Give names as Cloudericks Web Server and Cloudericks Web Server 2, respectively, while creation.

Tip

Name is internally represented using a tag with key set to Name.

• Subnets should be public...
