Is it possible to integrate APIGEE Edge with IBM Data Power Gateway.
Will the APIGEE edge can function without its own gateways ?
If not whether the APIGEE edge should be put in front layer of the IBM data power Gateway ?
Apigee Edge cannot "integrate" with a Datapower Gateway. Apigee Edge cannot function without the Apigee Edge gateways. From the perspective of Apigee Edge, the endpoints available in the Datapower gateway are just endpoints.
In that case, Apigee Edge sits in front of the Datapower gateway.
