Multiple SSL certificates can indeed be associated with an Elastic Load Balancer (ELB), specifically with Application Load Balancers (ALBs) and Network Load Balancers (NLBs) when using the TLS termination feature. This capability is essential for environments requiring secure connections to multiple domains or subdomains under the same load balancer. By supporting multiple certificates, ELBs can manage secure traffic efficiently and provide a seamless experience for users accessing different services or applications that may require different SSL certificates.

This feature is especially useful for applications hosted on the same platform that require distinct domains, allowing the ELB to dynamically select the appropriate SSL certificate based on the incoming request's hostname. Additionally, the use of Server Name Indication (SNI) enables this functionality by allowing the server to present multiple certificates on the same IP address and port number.

In summary, the ability to associate multiple SSL certificates with an Elastic Load Balancer enhances the flexibility and security of web applications, making it possible to serve different secure domains efficiently from a single load balancer.
