Most web traffic should be available over HTTPS. AWS makes this easy with Elastic Load Balancers (ELBs). When configured with an SSL certificate, an ELB will perform SSL termination and forward the traffic onto our group of non-encrypted web server instances.

Using an ELB is advantageous to offload many responsibilities to Amazon:

Maintaining uptime for the primary service DNS name Balancing traffic to one or more instances Re-balancing traffic when instances are added, removed, or become unhealthy Storing and applying your mission-critical secret SSL certificate Configuring critical aspects of HTTP like what SSL protocols, cypher and options are available and permitted
