Which process is an example of elastic load balancing?

What is elastic load balancer?
Elastic Load Balancing scales traffic to an application as demand changes over time. … As elastic load balancing uses request routing algorithms to distribute incoming application traffic across multiple instances or scale them as necessary, it increases the fault tolerance of your applications.
Does ALB strip headers?
But the ALB seems to strip the header and replace it with its own (which becomes X-Forwarded-Proto: http ), and then the backend application on the ECS servers sees http and writes all it’s links/resource paths as http, causing an insecure mixed content warning in Safari, Chrome, etc.

What are the three types of load balancers that ELB offers?
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use these types of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic.
Is Elastic Beanstalk like Kubernetes?
