Based on customer feedback and usage, we are pleased to announce that as of December 1, 2017, we’ve updated Azure API Management pricing to reflect the following:
Basic tier – a new, entry-level, production tier for customers with externally facing and cloud-first API programs. The Basic tier has the same features as the old Standard tier and identical SLA. It provides an economical way for customers to start using API Management, while their traffic volume is relatively low and is still ramping up.
Azure Active Directory and Azure Active Directory B2C support in the Standard tier – this allows customers to offer their employee, partner, and public developers to sign in to the Developer portal using their existing work or personal accounts.
Hourly billing for all tiers – this makes API Management more economical for customers who need an extra bit of scale for a fraction of a day.
Last, but not least, there’s no need to worry about call quotas or extra bandwidth charges anymore. Customers are free to use provisioned capacity to its fullest extent. We offer estimated maximum per-unit throughput numbers for all tiers on the pricing page, obtained through load testing under a specific set of conditions (same conditions for all the tiers, so these numbers provide a good idea of relative capacity across the tiers). Since maximum throughput is affected by many factors such as the number and rate of concurrent client connections, the kind and number of configured policies, payload sizes and backend API performance, it will vary from customer to customer. We recommend performing a realistic load test to size up the service correctly before launching into production.
