The three execution paths in simple scalable mode are each activated by appending the following arguments to Loki on startup:

- `-target=write` - The write target is stateful and is controlled by a Kubernetes StatefulSet. It contains the following components:
-- Distributor
-- Ingester
* Distributor
* Ingester
- `-target=read` - The read target is stateless and can be run as a Kubernetes Deployment that can be scaled automatically (Note that in the official helm chart it is currently deployed as a stateful set). It contains the following components:
-- Query front end
-- Queriers
* Query Frontend
* Querier
- `-target=backend` - The backend target is stateful, and is controlled by a Kubernetes StatefulSet. Contains the following components:
-- Compactor
-- Index gateways
-- Query scheduler
-- Ruler
- Compactor
- Index Gateway
- Query Scheduler
- Ruler
- Bloom Planner (experimental)
- Bloom Builder (experimental)
- Bloom Gateway (experimental)

The simple scalable deployment mode requires a reverse proxy to be deployed in front of Loki, to direct client API requests to either the read or write nodes. The Loki Helm chart includes a default reverse proxy configuration, using Nginx.

Query parallelization is limited by the number of instances and the setting `max_query_parallelism` which is defined in the `loki.yaml` file.

{{% admonition type="tip" %}}
You can see the complete list of targets for your version of Loki by running Loki with the flag `-list-targets`, for example:

```bash
docker run docker.io/grafana/loki:2.9.2 -config.file=/etc/loki/local-config.yaml -list-targets
docker run docker.io/grafana/loki:3.2.1 -config.file=/etc/loki/local-config.yaml -list-targets
```
