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

Ahh. So Mulesoft is at the heart of what my senior leaders at my shop are calling “powerhub”.

So if anyone wants to revisit my original post, now knowing Mulesoft is really powerhub... I’d appreciate any opinions. Using Mulesoft (as a cheaper alternative) than doing web services (and basically all cross platform processing) rather than directly from our IBM i applications in native languages (and sql).

Let me get more info on exactly what they are doing and I’ll report back. I just know two buzzwords for certain “powerhub” and “Linux”.

I cheer when an IBM i solution wins a competitive battle and I'm blue when
it goes the other way. I wish I could help more. I found the
https://powerhub.com/ link too, but was unsure if you were competing
against that (a suite of applications). Also, it wasn't clear whether the
competition might be between building vs.buying a product.

Jay, can you post the powerhub software link.

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

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.

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?
