Load Balancers

What?

• Devices responsible for distributing network (Layer 4) or application traffic (Layer 7).
  • Layer 4: distributes requests of transport and network layer protocols ie UDP, TCP, IP FTP
  • Layer 7: distributes requests of application layer protocols ie HTTP
• abstracts the fleet of servers as one big server to the outside world (in other words, POC is the load balancer instead of the server itself) or "service virtualisation"

Problem

As mentioned in #1558, users don't want be restricted by a specific project directory structure. Removing config.yaml will enable us in doing that.

Context

Purpose of config.yaml:

1. Provide configuration key values.
2. Get execution directory location (by validating project directory and which in return, enables us to run commands from anywhere inside the hasura project directory tree.)
