AWS లో లోడ్ బ్యాలెన్సింగ్ ఎలా పనిచేస్తుంది?

A LOAD BALANCER sits in front of multiple backend targets and distributes requests:
  Client → LOAD BALANCER → ┬→ Instance 1
                           ├→ Instance 2
                           └→ Instance 3
  → spreads traffic across targets (scalability + no single instance overloaded)
  → HEALTH CHECKS: routes only to HEALTHY targets (an unhealthy one is bypassed)
  → if a target fails, traffic goes to the others → HIGH AVAILABILITY
  → single entry point (clients hit the LB, not individual instances)
