The concept of logical and physical gateways
The API platform supports the idea of logical gateways and physical gateways. This concept is important as it has implications on the operational costs. Unlike a number of other products which charge based on the number of CPUs being used, the API platform is priced based on the number of logical gateways and API call volume in blocks.
As the following diagram shows, it is possible to have as many physical gateways deployed as desired within a logical gateway, where a physical gateway represents a single physical deployment of the gateway component. Not only that, the gateways can span as many hosting locations as desired:

The logical gateway, as its name suggests, is an abstract idea (as in there is no software deployed specifically for a logical gateway), which allows us to group collection(s) of APIs that we would want to manage in a similar way. For example, we might wish to manage...
