Confusion with PI 7.1 with integration scenario

Hi, expert,

I read a lot of documents before I have physically logged on to PI 7.1, I thought I had a very good idea about the new version. However when I am physically in PI 7.1, I found I get a little confused.

I know ES is a big thing in 7.1, but I will be working on integration (integration scenario), I thought this part is not changed from 7.0 to 7.1. Basically in 7.0, you defined message type and message interface, message mapping and interface mapping, then you go to ID to configure the integration scenario. However in 7.1, you do not have message interface anymore, instead, we have service interface under which you define operations, which is fine from ES perspective. But if I am only interested in integration, what I need is like PI 7.0: outbound interface, mapping, inbound interface, NOT the operation. Now how can I define 7.0 message interface in PI 7.1? (I know operation mapping is 7.0 interface mapping).

Can I make following understanding?

1) Operation in 7.1 is like messag interface in 7.0

2) Service Interface is a tool to group multiple related operations under one roof.

3) To define integration scenario, I do NOT need the modeling. Modeling is only relevant to model ES, NOT for integration scenario.

So if I am only interested in integration scenario, what is changed from PI 7.0 to PI 7.1?

Thanks for advice

Jayson
