Aaron One use case is that tenant would like to put all the servers in a single broadcast domain (thus single IP/subnet domain). The servers can include the 3 tier servers (web database and application server). Why would he do that - Because it is simpler.
Then the tenant would like to put security appliance firewalls between them. Lets say a database firewall appliance before the database tier or only app servers can access database servers. This is done in physical world but one needs to add switches and wire them from one broadcast domain to other. It is a pain. But in the virtual world this is lot simpler and convenient. prasadv On Wed, Apr 16, 2014 at 5:50 PM, Aaron Rosen <[email protected]> wrote: > This is true.
