| Who runs Grafana | Grafana Labs runs the stack, including managed metrics, logs and traces backends. | AWS runs the Grafana workspace. You manage users, data sources and content. | Microsoft runs it as an Azure service. | AceMQ engineers run Grafana OSS or Enterprise in your cloud account, cluster or data centre (Tier 3), or on infrastructure we run (Tier 4). |
|---|
| Where telemetry and credentials live | In Grafana Cloud's backends, or in data sources you connect to it. | In your AWS data sources, such as CloudWatch and Amazon Managed Service for Prometheus. | In Azure data sources such as Azure Monitor, and others you connect. | Wherever your data sources are. Credentials and dashboards stay inside your boundary at Tier 3. |
|---|
| Which versions you get | Grafana Cloud follows a different release cadence from Grafana OSS and Enterprise. | AWS decides which Grafana versions a new workspace can use. | Microsoft decides which versions the service offers. | The version you choose. Self-managed minors are supported for nine months, and the last minor of a major for 15 months. |
|---|
| Licence | A Grafana Labs subscription. | Grafana Enterprise is offered on the service; AWS and Grafana Labs set the terms. | Grafana Enterprise is offered on the service; Microsoft and Grafana Labs set the terms. | Grafana OSS is AGPLv3.
