A virtual appliance is a generic term for an application delivered as a prebuilt unit.
vApp is a VMware specific term for an application encapsulated within a vApp pool (which works on both hosted and hypervisors). The vApp can define a number of specific things about the appliance, such as performance/resource pools, IP address allocation policies, firewall requirements, etc.
I'm a newbie to vApps and I have a similar doubt.
1. I have a windows VM installed/running and I converted it to OVA format. Can I call this OVA file a vApp ? (Or simply a virtual appliance?)
On which vmware products/platforms can I play this OVA file ? (among ESX/ESXi, Workstation, Player etc.)
2. Now, using VMware Studio, I built a vApp by importing an already existing VM (in OVA format). Now, I have a vApp containing a single VM.
On which products/platforms can I play this vApp ?(among ESX/ESXi, Workstation, Player etc.)
thanks in advance.
1. It's a virtual appliance and it can be used in ESX(i), Workstation and Player.
2. vApps can only be used in a vSphere enviroment with DRS enabled.
The information is available in the administration docs.
