If you are operating in a cloud environment, there is an extra step to switch a virtual IP address between nodes. The following topics explain the background information and general approaches for each cloud environment:

• AWS Route Table Scenario
• AWS Elastic IP Scenario
• AWS Route53 Scenario
• Azure Internal Load Balancer Scenario
• GCP Internal Load Balancer Scenario

The following sections explain the configuration steps required in each scenario:

• Creating an AWS EC2 Resource (RouteTable Scenario)
• Creating an AWS EC2 Resource (Elastic IP Scenario)
• Creating an AWS Route53 Resource
• Azure – Using an Internal Load Balancer
• GCP – Using an Internal Load Balancer

SIOS Protection Suite also provides a resource type which will respond to TCP health check probes from an internal load balancer in order to route traffic to the current application host:
