Re: opinions - utilizing more of what the i has to offer

Thanks Steve.

That is one thing that crossed my mind is the security aspect but that hasn’t been mentioned. Only cost.

The way I see it is they are adding an unnecessary layer of complexity over the i to compensate for their lack of knowledge with what all the i can do.

And at this point probably won’t divert a different way even if the argument is strong enough.

Another thing I found odd they are doing...
A year ago I was tasked with developing an “inbound file monitor application” on the i to process incoming files. Powerhub side would be developed to support a custom MFT process to exchange files via sftp between our clients and vendor on our hosted system.
A year later I ended up designing, architecting, developing the entire MFT process on the i. Something I am proud of. It is now in production serving our clients nicely.
But now that same “leadership” is probing me for info on how I did things because they are developing the same thing on powerhub now.
My system is in its infancy and working fantastic.
I just don’t understand their motives sometimes.

an advantage of powerHub on a separate system is to limit your hacker
footprint. powerHub might copy a few IBM i tables back and forth between
the two system. customers who access powerHub only get access to that set
of data.

compare to an IWS or PHP. IBM i libraries tend to be very large. AP, AR
and warehouse tables in the same library. Using PHP you use db2_connect to
connect to the database - library. Once that connection is made the PHP
code typically has access to every table in that library.

Maybe they are referring to the costs of me (and my skillset as an ibm i
developer)??? Vs outsourced java programming on powerhub?

so our shop is an old traditional rpg shop supporting a fairly large

mostly green screen product.

it has a crappy screen scraping GUI on it I won't get into.

though we do have a hosted version in a SAAS model.

Our "senior IT leadership" is not of a mainframe/midrange background.

Our company recently started doing webservices for our clients, using

powerhub (and I'm not sure what else), but I do THINK it could be more
efficiently integrated right into our IBM i applications and database with
the use of say IWS (or a http web server) and using RPG/yAJL. I've done it
before at other shops.

So when I presented them (senior leadership) with this link...

https://www.ibmsystemsmag.com/Power-Systems/01/2020/rest-and-sql?utm_content=112727421&utm_medium=social&utm_source=linkedin&hss_channel=lcp-6225

and a comment from me saying...
"I know powerhub is all the rage but the i and your existing IBM i

talent can do it all."

they responded with...

"Yep, but the cost is much more than a cheap Linux OS running it on a PC

with a 10 year-old processor and low memory! Also this way it works with
ProductABC too! ;-) "

and

"while i truly am an i advocate in this case I have to agree with him

... heck I'm running Linux on a 15 year old Pc with no problems ... using
linux makes it easy to add additional virtual or physical servers and do
load balancing across the server pool ... "

I replied with...
"You guys certainly know your hardware better than I... but I don't see

where hardware even comes into the picture.

You simply configure a web services server on the current hosted IBM i.

Now our IBM i apps and IBM ilocal webservices (written in RPGLE or SQL) can
be invoked via http, directly on the i with programming by i developers who
know the database and programming already. I've proofed this out before
and had a working model on our DEV server once upon a time.

What cost? And... this way works with anything able to consume or

provide a REST webservice. We can return any modern data-interchange
format (xml, json)."

so, i'd like to hear the opinions on this board. I know what the i can

do, but I'm not sure what exactly they are talking about. Can anyone weigh
in on what they seem to be dead set on and what cost they are referring to?
