The App Project Manager only wants Ping, HTTP between
Tiers. ACL ?
What will happen when a third subnet will be used ? A new
ESX will be added ?

Complete visibility on VMs locations. Ease of troubleshooting.
If desired, VMs are gathered by affinity not by subnets nor vlans (*)
Contracts are built without IP addresses dependencies
1 subnet is created in only one click and immediately available for the whole
infrastructure
APIC configuration effort is the same independently of the number of Leaves, ESX,
VMs, …
Use of APIC Open Northbound interface to ease automation, used as a Cloud
connector, for tailor made operational jobs, …
Ease of monitoring by breaking the current Vlan/Subnet paradigm
Networking attributes are automatically pushed from APIC to Vcenter. VM admin has
just to assign the right PortGroup to the VM.
(*) If needed, ACI can stick to a classical network centric approach where 1 BD = 1 subnet & 1 EPG = 1 Vlan
