Vespa charges by the machine resources allocated to your applications in three dimensions:
|Per vcpu hour:||$0.12|
|Per memory Gb hour:||$0.012|
|Per disk Gb hour:||$0.0004|
In production zones, the resources you allocate are precisely what you specify in services.xml for the duration the application is deployed.
In dev, and test zones, applications will by default be downscaled and you will be charged for the capacity actually used. In test zones, applications will only allocate resources while tests are running.
In addition to machine resource costs, network costs incurred by your application are passed on to you at standard AWS prices. These depends only on how you use your applications.
