Assuming you have multiple CPUs (non-virtual) running FDS for the same application, in all of those scenarios you still need a license per-CPU.
The only scenario where you do not need a license is where FDS is running on one CPU (and it can support as many applications as you like). If you were to have separate applications (and application here means business purpose application, not necessarily Flex application) you could even have one FDS CPU per application. However, I consider this scenario unlikely for a business, but more possible for personal use.

Hi All, We need to install an application where a number of screens are developed using FLEX. We could have different environment-setups in which the application may be deployed and need to know in what scenarios we will have to get separate licences of FLEX DATA SERVICES for application deployment and maintenance (Would be of great help if someone could explain the difference in all the four environment settings) : 1. Non-Clustered CPU environment 2. Clustered Environment 3. Distributed Environment 4. Mirroring Environment All help would be appreciated. Thanks Sanjay
