When you run code on DataCamp Workspace, you run this code in an isolated environment on one of DataCamp-managed cloud servers that you share with other users. Typically, 8 to 16 users are using the same physical server. To ensure every user gets a fair share of the processing power available on the server, every user gets a type of 'budget', which is expressed as a number of vCPUs, short for virtual CPUs. If every user gets 0.5 vCPU and the CPU resources of the server are contended (because everyone is doing heavy computations), every user gets a fair share of the CPU resources. If one of the user has a paying subscription, they get 4x more 'budget' on the CPU resources. In that case, if CPU resources are contended, the code of the paying user will finish 4x faster.
