API Management stv1 platform retirement - Global Azure cloud (August 2024)
APPLIES TO: Developer | Basic | Standard | Premium
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 in the global Microsoft Azure cloud. A more current compute platform version (stv2) is already available, and provides enhanced service capabilities.
Note
For API Management instances deployed in Microsoft Azure Government cloud or Microsoft Azure operated by 21Vianet cloud (Azure in China), the retirement date for the stv1 platform is 24 February 2025. Learn more
The following table summarizes the compute platforms currently used for instances in the different API Management service tiers.
| Version | Description | Architecture | Tiers |
|---|---|---|---|
stv2 |
Single-tenant v2 | Azure-allocated compute infrastructure that supports availability zones, private endpoints | Developer, Basic, Standard, Premium |
stv1 |
Single-tenant v1 | Azure-allocated compute infrastructure | Developer, Basic, Standard, Premium |
mtv1 |
Multitenant v1 | Shared infrastructure that supports native autoscaling and scaling down to zero in times of no traffic | Consumption |
For continued support and to take advantage of upcoming features, customers must 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.
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.
Is my service affected by this?
If the value of the platformVersion property of your service is stv1, it's hosted on the stv1 platform. See How do I know which platform hosts my API Management instance?
What is the deadline for the change?
Support for API Management instances hosted on the stv1 platform will be retired by 31 August 2024.
What do I need to do?
Migrate all your existing instances hosted on the stv1 compute platform to the stv2 compute platform.
If you have existing instances hosted on the stv1 platform, follow our migration guide to ensure a successful migration.
What happens after 31 August 2024?
Your stv1 instance will not be shut down, deactivated, or deleted. However, the SLA commitment for the instance ends, and any stv1 instance after the retirement date will be scheduled for automatic migration to the stv2 platform.
End of SLA commitment for stv1 instances
As of 1 September 2024, API Management will no longer provide any service level guarantees, and by extension service credits, for performance or availability issues related to the Developer, Basic, Standard, and Premium service instances running on the stv1 compute platform. Also, no new security and compliance investments will be made in the API Management stv1 platform.
Through continued use of an instance hosted on the stv1 platform beyond the retirement date, you acknowledge that Azure does not commit to the SLA of 99.95% for the retired instances.
Automatic migration
Starting 1 September 2024, we'll automatically migrate remaining stv1 service instances to the stv2 compute platform. All affected customers will be notified of the upcoming automatic migration a week in advance. Automatic migration might cause downtime for your upstream API consumers. You may still migrate your own instances before automatic migration takes place.
