By using DS cloud servers you avoid having to configure and maintain the network and server infrastructure required for 3DOrchestrate and the other 3DEXPERIENCE platform servers (3DSpace, DSLS license server, etc.).
The graphic below describes the various combinations of hardware and software infrastructure needed for on-premises vs. on-cloud solutions.

- Token simulation licensing
In the token licensing scheme, your company has purchased a certain number of simulation tokens which are available from a pool. When a user executes a simulation, a particular number of tokens are checked out from the pool. The number of tokens required depends on the complexity of the simulation model, the step types, and the requested performance. When the simulation completes, the tokens are returned to the pool for use by other simulation jobs. If sufficient tokens are not available at any time for a new simulation, the job will wait for more tokens to be freed.
Tokens are suitable for sustained simulation workloads over the license term.
Token licensing is available when you are connected to a Dassault Systèmes cloud server or when a system administrator has configured simulation tokens on your company's on-premise DS license server.
- Credit simulation licensing
This scheme uses one-time consumable licensing credits to execute a simulation. Using credits is more efficient for peak computing workloads when larger, more complex simulations are being run occasionally. The number of credits consumed depends on the complexity of the simulation model, the step types, and the execution performance requested. When a credit is consumed, it is deducted from the total count available.
Credit licensing is available only when your company has purchased cloud roles and you are connected to a Dassault Systèmes cloud server.
