General Availability: Azure API Management Premium tier
The Premium tier of Azure API Management simplifies high availability and massive scale. (Each unit includes 1 billion API calls per month.) Geodistribution provides a turnkey way for you to host an API Management instance in multiple Azure datacenters with configuration automatically synchronized around the world. Added virtual private network (VPN) connectivity means you can connect the API Management proxy to your Azure Virtual Network (including ExpressRoute) to help achieve maximum security and performance when tackling hybrid scenarios. Integration with Azure Active Directory provides better support for internal and business-to-business API programs, and allows developers to sign-in to the Azure Management Portal with their corporate credentials. Premium-tier pricing goes into effect May 1, 2015. Review the new pricing information on the API Management Pricing webpage. For more information, please visit the API Management webpage.
