Future-Proof Your API Strategy: Azure APIM migration to stv2

As we embrace the continuous evolution of cloud services, the must-have part is to stay updated with the latest infrastructure enhancements.

Azure API Management’s transition from stv1 to stv2 platforms is one such update that demands our attention.

I was working on this migration and thought it would be exciting news for all the Azure API Management enthusiasts. Azure has introduced a significant update with the release of stv2 in API Management services. In the article, I have captured the differences between stv1 and stv2, the necessity of migrating, and some key considerations for a seamless transition.

What’s Changing

The stv1 platform, the initial single-tenant compute infrastructure, is set to retire on August 31, 2024. Its successor, stv2, offers a more robust architecture with support for availability zones, private endpoints, and enhanced security features like Azure DDoS protection.

Differences between stv1 and stv2:

• Protocol Support: stv2 supports newer protocols such as OpenAPI 3.0 and gRPC, offering enhanced flexibility and adaptability.
• Developer Portal Experience: stv2 provides a revamped developer portal with improved customization options and a more intuitive user interface.
• Enhanced Policy Engine: stv2 introduces a more powerful policy engine, allowing for advanced customization and control over API behaviours.

Why migrate from stv1 to stv2:

• Security and Compliance: stv2 offers enhanced security features and compliance capabilities, ensuring a more robust and secure API management environment.
• Performance and Scalability: Migrating to stv2 can unlock performance improvements and better scalability, catering to evolving business needs.
• Future-Proofing: As stv1 reaches its end of support, migrating to stv2 ensures access to the latest features, updates, and support from Azure.

Known issues and recommendations for migration:

• Custom Policies: Review and update any custom policies to ensure compatibility with stv2's enhanced policy engine.
• Data Migration: Plan and execute a seamless data migration strategy to prevent any loss of configurations or data during the transition.
• Testing and Validation: Thoroughly test APIs and related functionalities post-migration to identify and address compatibility or performance issues.
