This may be a naive question so please bear with me. :)

In the below diagram, there is a load balancer in front of 3 instances...

Is it possible to configure the load balancer (ELB/Google Load Balancer/Azure load balancer...basically any) to forward/broadcast every request to all instances... If not load balancer, what component natively provided by IaaS providers can broadcast such requests to all instances?

enter image description here

I saw a similar question, but it was from 2016 and was hoping if anything changed?

Nothing has changed. The purpose of a Load Balancer is to distribute traffic, not to broadcast traffic.

The closest AWS service that matches your diagram is Amazon Simple Notification Service (Amazon SNS).

It uses a public/subscribe model:

  • An Amazon SNS Topic is created
  • Various subscriptions can be attached to the topic (Email, SMS, AWS Lambda, HTTP endpoint, Amazon SQS queue)
  • A message is sent to the topic and it is forwarded to all subscribers
