# Manage Lifecycle

## Service States
Your Thanos service can be in the following states:

| State | Description |
|-------|-------------|
| **Building** | Service is being provisioned |
| **Running** | Service is operational and accepting connections |
| **Rebuilding** | Service is being updated or scaled |
| **Poweroff** | Service is stopped |

## Scaling
Change your Thanos plan to scale resources up or down:

1. **Via [Portal](https://portal.exoscale.com/)**: DBaaS > Your Service > Change Plan
2. **Via [API]({{< ref "reference/api/dbaas/dbaas-thanos/" >}})**: `PUT /dbaas-thanos/{name}` with new `plan` value
3. **Via CLI**

Available plans range from `startup-4` to `business-64`. See [Overview]({{< relref "../../overview/_index.md" >}}) for plan details.

> [!NOTE]
> Scaling may cause brief service interruptions. Plan changes on Business plans benefit from high availability to minimize downtime.
