## Choose a learning path

Select the data source that matches your environment.

> **Note:** A [Grafana Cloud account](/signup/cloud/connect-account) is helpful for hands-on practice, but completely optional. You can read through any learning path to understand the configuration process without configuring yourself.

## Looking for a different data source?

We have learning paths for the data sources above. For InfluxDB, Loki, Elasticsearch, CloudWatch, PostgreSQL, Google Sheets, or any of the 150+ other data sources, use the [data source documentation](https://grafana.com/docs/grafana/latest/datasources/). The docs include setup instructions, query examples, and troubleshooting tips.
