System limits and maximums
By design, Pega Platform is highly scalable. You can support one user or thousands of users. You can operate the system on an inexpensive Windows laptop or on a collection of enterprise servers, each with multiple processors.
Similarly, there are no inherent restrictions on the size or number of work items, assignments, history instances, data instances, and so on. Expanding your investment in disk space and database management facilities automatically expands the capacity of your applications.
The following maximums and limitations apply to this version. Contact your Pegasystems Global Services representative if these affect your operation.
