vCloud Director Competition

Hi,

We are pursuing a private cloud initiative and are a big VMware shop looking for conducting some due dilligence and PoC's in the vCloud Director space (vCloud suite). Our Hypervisor platform is majorly VMware, Networking is all going to be Nexus 1000v pretty soon and we also concluded and might be moving ahead with vShield App (VCNS standard) pretty soon.

There are 2 main questions i have for this community -

1. Who are the top 3/4 competitors for vCloud Director in the resource aggregation space?

2. Who are the top 3/4 competitors for vCloud Automation center in the Orchectration space?

Thanks,

AB
