Re: SOAP vs. REST

Why not IWS? The following is my personal opinion and one that I have shared with IBM on many occasions.

1) The inner workings are "hidden" behind a Java App Server. It is wonderful when it is working and a nightmare to debug (unless they've made major changes recently that I am not aware of) when it isn't. For a long time redeploying a service was a pain - I believe they are supposed to have fixed that now but I haven't played with the current version.

2) When things change in the REST world and you need some new authentication method or whatever you are stuck until IBM updates the wizard and off course you have to be on a release that the update is supported on.

3) One of my biggest peeves - the documentation is in "unixese" and while some of the guides are more helpful I have encountered problems with them not being updated to match the software. Not a problem if the docs were in English but ...

4) When I ran some performance tests a while back a regular simple RPG/Apache/JSON combination handled between 3 and 10 X the number of transactions in a given time frame.

5) There are a lot more people on the lists who can offer advice on how to make RPG drive a REST web service than there are who are familiar with IWS. When it comes to node/Python/PHP that number climbs from "lots" to "masses".

As I noted in my original response i have used IWS for a proof of concept, and one client continued to use it in production because the transaction volume was relatively low and the simplicity worked for them in those circumstances.

REST for sure. And personally I would not use IWS for a multitude of
reasons. I love it for proof of concept stuff but I'd rather "roll my own"
using PHP, node, Python or RPG.

Folks:



I'm about to do an incredibly scary thing, start to develop my own

software

that includes the use of IWS. To suggest I'm starting from the

beginning is

at best charitable. I can architect the software, that's easy. Actually
doing the development, my RPG credentials were revoked a long time ago,

so

there's that learning curve. Then there are some decisions to be made in

the

architecture. To that end:



So as part of the software planning process the question comes up SOAP

vs.

REST. I'll assume based on the threads I've seen lately that most folks
would prefer to use JSON, therefore REST as opposed to SOAP which would

use

XML.



This will be entirely IBM i based software with both traditional
languages/objects and some open source components as well. DB2 will be

the

database of record.



Thoughts?
