3 Tier application - how to ?

Hi guys,

I need to create a 3 tier application for study purpose and I was wondering is there is any preconfigured vApp for this?

Alternatively, I would have to create it from scratch and to do so I was thinking to use 3 Linux VMs, problem is I'm not either a DB expert nor an application developer. I could probably set the Web server but I still need the other 2 tiers.

Any idea or suggestion is well accepted.

Thanks.
