# Server groups

> Organize backend instances behind a Nubis load balancer so traffic routing stays predictable.

## Group backends by service role

Server groups are the operational idea behind a clean load-balancer backend: the instances in the group should do the same job, expose the same ports, and be safe to route traffic to interchangeably.

## Good backend-group habits

* Keep one clear purpose per backend group.
* Avoid mixing unrelated applications in the same traffic pool.
* Make sure each server in the group is bootstrapped and monitored the same way.
* Pair backend membership changes with deployment and rollback steps.

## When your Console uses a different term

If Nubis exposes this concept as target pools, backend pools, or attached instance sets, the operating guidance stays the same.
