API Management max concurrent sessions

Question

Hi, i need API Management to connect with app service APIs, but it's not supporting the demand of +20 000 concurrent sessions. I combined API Management with Azure Service Bus but the problem is API Management is not supporting the demand. Any idea which service can i use?? Api Management is already in Premium Tier.

Answer 1

@David Gonzalez D Thank you for reaching out to Microsoft Q&A. Based on my understanding, you are looking to establish +20,000 concurrent connections to backend API(s) (here: App Service) and observed some issues with API Management.

As per APIM limits docs, for premium tier the limit is 2,048 per unit and you can add up to maximum of 12 per region. Can you let me know how many units you have tested with? With 10 scale units, you can handle 20,000 concurrent connections. Please note, Connections are pooled and reused unless explicitly closed by the back end.

Also check Pricing page for more info regarding this and if you have a demand to increase more, our Azure Support can further help you with that. Feel free to let me know if you want me to connect you with them.

Do we have a way to see the Concurrent connections in APIM?
