SAP PI Architecture (3 or 2 Tier) ?

288 Views

Hi all,

at the moment I am collection (dis)advanteages for a 2 tier or 3 tier architecture.

Maybe you have some additional points

2 tier

-


Pro:

Less Costs

Contra:

Quality tests can only be done with high effort

System has to be connected to several systems (at least development and quality ECC)

3 tier

-


Pro:

Fits to ECC Architecture where you have normally a 3tier architecture

Development can be done in parallel to tests

Mass tests can be done easier

Possibility to use Q as backup system in case of Problems with Productive system

Contra:

Additional effort to keep system in synch (service package etc.)

Or would you already go to a 4 resp. 5 tier architecture?

Thanks for any input

cheers,

Stefan
