Does ELB support SSL termination?

You can now create a highly scalable, load-balanced web site using multiple Amazon EC2 instances, and you can easily arrange for the entire HTTPS encryption and decryption process (generally known as SSL termination) to be handled by an Elastic Load Balancer.

What is SSL termination in ELB?

SSL termination is the term pointing to proxy servers or load balancers which accepts SSL/TLS connections however do not use the same while connecting to the back end servers. E.g. A load balancer exposed to the internet might accept HTTPS at port 443 but connects to backend servers via HTTP only.

Where can I terminate SSL?

SSL termination is the process of decrypting traffic before its passed on another server such as Access Gateway. When used with a load balancer, SSL can be terminated at the load balancer or encrypted traffic can be passed directly to Access Gateway and SSL terminated there.

What is the difference between classic and application load balancer in AWS?

The Classic Load Balancer operates on both the request and connection levels. A Classic Load Balancer is recommended only for EC2 Classic instances. The Application Load Balancer operates at the request level only. If you’re dealing with HTTP requests, which you are for your web application, you can use this.

How does SSL termination work?

How Does SSL Termination Work? SSL termination works by intercepting the encrypted traffic before it hits your servers, then decrypting and analyzing that traffic on an Application Delivery Controller (ADC) or dedicated SSL termination device instead of the app server.

Does Classic load balancer supports SNI?

You can create a load balancer that uses the SSL/TLS protocol for encrypted connections (also known as SSL offload). Classic Load Balancer does not support Server Name Indication (SNI) on your load balancer.

Does ALB support SNI?

Today we’re launching support for multiple TLS/SSL certificates on Application Load Balancers (ALB) using Server Name Indication (SNI). In order to use SNI, all you need to do is bind multiple certificates to the same secure listener on your load balancer.
