Generally Available: Azure API Management Premium v2 now supports multiple custom domains

Organizations often need to expose APIs, developer portals, and management endpoints under different branded or organizational domain names- — for example, api.contoso.com for external partners, apis.hrportal.contoso.com for an internal HR platform, and dev.europe.contoso.com for a regional developer portal. Until now, achieving this level of separation frequently required additional API Management instances, increasing operational complexity and cost. With this update, Azure API Management Premium v2 enables multiple custom domains within a single instance across gateway, developer portal, and management endpoints. This allows organizations to: * Configure distinct hostnames for different endpoints and audiences * Align API experiences with business units, products, or regional brands * Simplify domain-scoped networking and security policies * Reduce the need for separate APIM instances solely for domain separation For enterprises managing large and distributed API estates, this provides greater flexibility in how APIs and developer experiences are exposed while improving operational efficiency and maintaining centralized governance.
