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

If you are using an ESB like Mule it makes a certain amount of sense to
centralise and organise communications through it.
Have a large number of directly communicating systems can quickly become
very hard to unravel and manage when things change. Organising all data
exchanges through the one broker can help unravel this.

Take for example, a situation where system a is communicating directly with
system b.
If system b is replaced with system c, then both system a and system c
probably need to make changes.
With a broker then the changes should be confined to system c.
There's also the security aspect that if all external communications are
through the broker then (theoretically) it's easier to secure and manage.

I see it the same way.

Yes the rpg/sql devs write all the applications with related industry biz
logic to write the data to db2 database.

Why not let us handle the microservice end if it that simply serves the
data up to any off platform call!?

My guess is that before I came along the existing ibm i talent knew (and
still knows) very little if any at all in regards to cross platform
integration.

And decision was made upstream to not even bother training them.

Now they are heavily invested in Mulesoft, thinking that adding another
layer of NON ibm i architecture will help them better “extract” data from
the system.

Unfortunate

As I understand it, real RPG programmers are still going to write the

programs that touch the data on the i? So you are looking at spending
money for a utility and teaching your staff an entirely new paradigm as
compared to spending a couple of weeks bringing your current staff up to
speed with your-already-paid-for IWS wizard?

Why not take a week, maybe two, to try a few simple IWS web services

projects? All it'll cost you is some hours and it might save you tons of
money.

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).
