An Application Load Balancer (ALB) is specifically designed to handle HTTP/HTTPS applications and offers advanced request routing capabilities, making it capable of distributing traffic based on the content of the request (such as URL path or host field). This would effectively manage the sudden spikes in traffic by distributing it across multiple EC2 instances, ensuring high availability and elasticity. Network Load Balancer is typically used for TCP, UDP, and TLS traffic where extreme performance and static IP is necessary for the load balancer. Classic Load Balancer is a legacy option that provides basic load balancing across multiple EC2 instances but with less advanced routing capabilities than ALB. A Global Accelerator primarily improves global application availability and performance by directing traffic to optimal endpoints over the AWS global network.
