Self-hosted API Gateway
Sven Malvik · Apress eBooks · 2022
When you call an API in Azure API Management, the request is handled by the managed API gateway component of your instance, which then forwards the requests to a backend web service. In cases where a backend web service is hosted nearby and the traffic is going via the Azure backbone, this is fine because latency is kept to a minimum and security to a maximum. However, there are other cases where backend web services are hosted outside of your Azure tenant and where the traffic to backend web services goes via the public Internet and not via the Azure backbone. Those cases can not only be challenging security-wise as data is sent out of the network but might also break compliance policies of an organization where traffic must stay local.
