| 13 | +# stv1 platform retirement (August 2024) |
| 14 | + |
| 15 | +As a cloud platform-as-a-service (PaaS), Azure API Management abstracts many details of the infrastructure used to host and run your service. **The infrastructure associated with the API Management `stv1` compute platform version will be retired effective 31 August 2024.** A more current compute platform version (`stv2`) is already available, and provides enhanced service capabilities. |
| 16 | + |
| 17 | +The following table summarizes the compute platforms currently used for instances in the different API Management service tiers. |
| 18 | + |
| 19 | +| Version | Description | Architecture | Tiers | |
| 20 | +| -------| ----------| ----------- | ---- | |
| 21 | +| `stv2` | Single-tenant v2 | Azure-allocated compute infrastructure that supports availability zones, private endpoints | Developer, Basic, Standard, Premium<sup>1</sup> | |
| 22 | +| `stv1` | Single-tenant v1 | Azure-allocated compute infrastructure | Developer, Basic, Standard, Premium | |
| 23 | +| `mtv1` | Multi-tenant v1 | Shared infrastructure that supports native autoscaling and scaling down to zero in times of no traffic | Consumption | |
| 24 | + |
| 25 | +To take advantage of upcoming features, we're recommending that customers migrate their Azure API Management instances from the `stv1` compute platform to the `stv2` compute platform. The `stv2` compute platform comes with additional features and improvements such as support for Azure Private Link and other networking features. |
| 26 | + |
| 27 | +New instances created in service tiers other than the Consumption tier are mostly hosted on the `stv2` platform already. Existing instances on the `stv1` compute platform will continue to work normally until the retirement date, but those instances won’t receive the latest features available to the `stv2` platform. Support for `stv1` instances will be retired by 31 August 2024. |
| 28 | + |
| 29 | +## Is my service affected by this? |
| 30 | + |
| 31 | +If the value of the `platformVersion` property of your service is `stv1`, it is hosted on the `stv1` platform. See [How do I know which platform hosts my API Management instance?](../compute-infrastructure.md#how-do-i-know-which-platform-hosts-my-api-management-instance) |
| 32 | + |
| 33 | +## What is the deadline for the change? |
| 34 | + |
| 35 | +Support for API Management instances hosted on the `stv1` platform will be retired by 31 August 2024. |
| 36 | + |
| 37 | +After 31 August 2024, any instance hosted on the `stv1` platform won't be supported, and could experience system outages. |
| 38 | + |
| 39 | +## What do I need to do? |
| 40 | + |
| 41 | +**Migrate all your existing instances hosted on the `stv1` compute platform to the `stv2` compute platform by 31 August 2024.** |
| 42 | + |
| 43 | +If you have existing instances hosted on the `stv1` platform, you can follow our [migration guide](../compute-infrastructure.md#how-do-i-migrate-to-the-stv2-platform) which provides all the details to ensure a successful migration. |
