LoadBalancing
Distributing traffic across multiple instances — round robin, least connections, health checks.
Why we need this / what value this brings
Distributing traffic across multiple instances is what makes horizontal scaling and zero-downtime deploys possible.
When to use this
Once there's more than one backend instance running — not relevant at single-instance scale.
How to use or implement this
Use health checks so the load balancer stops routing to an unhealthy instance automatically.
Research questions
- Not yet relevant at single-instance scale, but worth knowing before Localz's backend needs a second instance.
