In the basic tier of APIM, how many concurrent api requests can be processed comfortably without affecting the performance?

Question

Hi,

I would like to know the limitations of APIM (basic tier). How many concurrent requests it can handle without performance degradation. I don't see any official document providing any such information.

Thanks.

@Smruti Ranjan Nayak Thanks for reaching out.

It would not be possible to estimate the concurrent requests that can be processed for the basic tier.

The reason is that the number of concurrent requests that an Azure API Management instance can handle without performance degradation depends on various factors such as the number and rate of concurrent connections, the kind and number of configured policies, request and response sizes, and backend latency and you need to perform the load testing to find what would be the ideal limit for under a normal scenario.

The practical upper limit depends on service configuration including pricing tier, service capacity, number of scale units, policy configuration, API definitions and types, number of concurrent requests, and other factors.

The limits of APIM are documented here.

Let me know if you have any queries or concerns.
