Platform vs. equipment?

alistair harris

I am trying to model the link between systems and the underlying, increasingly physical layers they depend upon.

 

I started by defining platforms comprised of technologies (e.g.. web farm, comprised of web server, o/s, hardware, etc.) with the aim of linking them to the already defined systems. However, there is no modeler which allows systems and platforms to be linked in this way.

 

The communication and systems interaction modeler allows systems, databases and equipment, but not platform.

 

The platform modeler allows only platform & technology

 

I can create an association between a platform and a system, and thus create a navigator model, but this suggest to me that I am doing something wrong - or do not understand the difference between platform/technology and equipment/database.

 

Help and advice welcomed please

I'm dealing with a similar problem now, and am sorry to see you didn't get any responses here. 

 

I don't have access to provision right now, but I'm wondering if it's possible to change the laws of the system integration model to use platforms.  I'll probably try this tomorrow.

Hello to both of you.
Off the shelf, this is what you need to do to link systems to platforms & technology
In a system interaction modeler, you place your system on top of an equipment (which can represent a logical server).
From that equipment object you drill down into a platform model to elaborate the technologies.

2 option : create a custom object which you are going to use in the system interaction model (could name it logical server or anything relevant to your methdology) to link a system to. Then authorize that custom object to be the subject of the platform model to futher detail the platform.
Hope this helps,;
THanks,
Thierry.

Sorry, instead of 2 option, please read 2nd option.

Hi

You can always use a navigator model which can show any and all assocations / links etc, and objects.  From a platform object use the System utlization association.

 

As technologies can be associated with multiple platforms it is an effective way of creating re-usable paterns that can be associated with systems in the above manner.
