Introduction to Load Balancing

Load balancing is a crucial component of System Design, as it helps distribute incoming requests and traffic evenly across multiple servers. The main goal of load balancing is to ensure high availability, reliability, and performance by avoiding overloading a single server and avoiding downtime.

Typically a load balancer sits between the client and the server accepting incoming network and application traffic and distributing the traffic across multiple backend servers using various algorithms

I am wondering why do we need the Load Balancer separately and in many configurations API gateway is also doing the Load balancing, so what's the reason and the good practice to follow?'

Hi, I am curious to understand that the entry level webserver/load balancer that accepts traffic from all over the globe handles soo many request on a given port ? I understand we can vertically scale it or horizontally. Even if we horizontally scale it there has to be some sever that accepts clients connections and distributes that request to the underline services.

Thus whichever software/hardware is sitting at the front gate handles Millions of requests on a SINGLE port ?

Are load balancers 2-way ? If so how are they set up to handle incoming requests and outgoing responses or are there multiple 1-way balancers for each?

We began with Load Balancer, however without the context of vertical scaling, this concept can suddenly become a black box. Would suggest to have some pre-requisite knowledge in the introduction so that people know what homework to do before we dive in.
