Options
- ADeploy EC2 instances in multiple AWS Regions behind a Network Load Balancer (NLB).
- BDeploy EC2 instances in multiple Availability Zones behind a Network Load Balancer (NLB).
- CDeploy EC2 instances in multiple Availability Zones behind an Application Load Balancer (ALB).
- DDeploy EC2 instances in multiple AWS Regions behind an Application Load Balancer (ALB).

Explanation
A Network Load Balancer (NLB) supports TCP traffic, which is required for the custom protocol. Deploying EC2 instances across multiple Availability Zones behind the NLB with health checks ensures high availability and automatic failover within the same Region. Application Load Balancers do not support raw TCP traffic.
