"API Mullet" has got to be my favorite description of this type of system. Well done.

I can't take credit for it, alas. It was from an Axway blog post. It's sort of backwards too, if you think about it - business in the back and party in front.

I don't know, the "front" is all business - ordered, structured, conforms to the standards. The back is a jumbled, messy, non conforming. It's a party back there.

API Tellum?

Out of interest SOAP services tend to be message/operation based, while REST is deliberately not this.

How do you go about proxying REST style requests to a SOAP backend?

Can't speak for the parent but having tackled similar efforts before I find that almost all APIs regardless of the implementation flavor (including SOAP and RPC) are readily understood as CRUD systems creating/reading/updating/deleting things), and the mapping from CRUD to REST is straightforward. In practice this generally means mapping from a SOAP call like `SetPostAuthor` to a REST call like `PUT /post/:post_id/author`. There are always some gnarly bits along the way, but the basic structure usually comes together pretty easily.

Yup, petty much. If you're willing to be a little flexible in your application of RESTful concepts and are okay with your abstractions leaking a bit, it's not especially tough.

That's the easy case.

A harder case is when you have a "service" layer which also has a large collection of queries at various levels of abstraction.

These map poorly into resources, where you want a single level of abstraction per resource. And they map badly to legacy consumers, who've grown comfortable to having a collection of special knobs and dials perfectly shaped for their exact needs.

Heh, I never thought I'd meet an Axway product user on HN. What are you using? Gateway? Integrator?

Gateway is pretty non-specific if you're talking Axway. It could mean XFB Gateway, Gateway Interchange or API Gateway... and I'm not even sure that's the whole list.

I meant XFB. It was the only product that was referred internally just as "Gateway". "Gateway Interchange" was "Interchange" and "API Gateway" was "API Gateway".

Gateway, under oracle branding.

me too! (not the oracle version though) :(

It does suck a bit, I've also sent Layer 7 into production which is just as bad as Axway. Typical Vendorware.

The AWS Gateway is pretty enticing. Solves lots of the API Gateway problem space very quickly and super cheap. We could run our production instance for about $2 a month I reckon, vs a 6 figure sum for the vendor tech.

May God have mercy on your soul :o)

;_;

Just curious, but why Oracle-branded rather than direct?

have you look at the open source KONG https://github.com/mashape/kong ?

do you have a website?

Not really, why do you ask?
