For an application requiring TCP communication and high availability:

Network Load Balancer (NLB)is the best choice for load balancing TCP traffic because it is designed for handling high-throughput, low-latency connections.

Auto Scaling groupensures that the application can automatically scale based on demand, adding or removing EC2 instances as needed, which is crucial for handling user growth.

Option C (Application Load Balancer): ALB is primarily for HTTP/HTTPS traffic, not ideal for TCP.

Option D (Manual scaling): Manually adding instances does not provide the automation or scalability required.

Option E (Gateway Load Balancer): GLB is used for third-party virtual appliances, not for direct application load balancing.

With AWS Shield Advanced, you can add multiple protected resources (like ALBs) to a protection group and choose an aggregation type for mitigation and billing.

Sum aggregation provides combined protection for all resources in the group during blue/green deployment.

This ensures the new ALB inherits protection and avoids additional configuration during deployment.
