Currently, `LoadBalancer` is the only supported kind of HTTP `Service` (see below).
However, since Traefik is an ever evolving project, other kind of HTTP Services will be available in the future,

### Weighted Round Robin (service)
The WRR is able to load balance the requests between multiple services based on weights.
This strategy is only available to load balance between [services](./index.md) and not between [servers](./index.md#servers).
This strategy can be defined only with [File](../../providers/file.md).
