All we are trying to do here is to minimize the cost because of APIM premium instances. we are having 3 different APIM Premium instances for different regions ( Europe and north America).
I am exploring some options and see if we could use Azure Front door to route the traffic the different geographic location (based on the latency) and it should also provide WAF and we can keep one external API domain to accept the traffic for our external APIs.
Questions around are -
1) Would Front door with Basic APIM would work in above use case or what am in missing for not having the premium APIM.
2) What if i decide to have traffic manager along with Basic APIM instances - would that also work or what is preferred ?
Thank you for looking at the question and appreciate if anyone have any experience around this approach,
