Creating an AWS EC2 Resource (Elastic IP Scenario)

Here we will discuss how to switch between nodes using an Elastic IP address by creating an entry that points to the active node.

Assign Permission to Update Route Table Entries to Instances

!To complete the steps below, the AWS CLI must be installed on each node.

• Install AWS CLI

• Assign Permission to Use EC2 Recovery Kit

You will also need to acquire an Elastic IP. In the example below the Elastic IP address is 107.20.190.240. Note that this IP address is an example value.
