load balancer
A load balancer routes requests among service instances.
Use this when A service runs on multiple instances that must share traffic safely.

“We're running two copies of the server now. Some users get logged out randomly and some requests hit a server that's still starting up. How should traffic be split?”
with the term · How do you ask a model for load balancer?
Verify this service behind its load balancer. Remove one instance during traffic and check session behavior, readiness, and in-flight requests.
What is load balancer?
A load balancer distributes incoming traffic across configured targets. Routing and health-check settings determine which targets receive work; application readiness and failure behavior need separate verification.
Why does load balancer matter when vibe coding?
Adding instances may expose state or connection assumptions hidden in one process.
How do you do load balancer?
Define readiness and state ownership, then test routing when an instance fails.
What goes wrong with load balancer?
Sending traffic to a process that has started but is not ready.
