Reference Architecture for on site deployment for internal and external use (own public and private cloud).

[#1]

Hi,

I am looking for building API integration layer to expose APIs to Internal and External Apps (Developers).

For this matter, as per company Security policy, External Access GW shall be on our Public cloud, (DMZ), whereas Internal GW shall be place on Internal Cloud (network) with no access from Internet.

However, back-end API integration layer shall be common, so integration to back-ends happens only once ( as well as throttling is done centrally towards back-en systems).

I'm attaching high level diagram to your reference.

Please suggest how Apigee Edge topology would look like.

Thanks,

Vaidotas
