Using isolated regions to separate groups of usersWithin a system, it is often desirable to maintain separate work areas for specific groups of users. For example, it may be desirable to separate a production environment from the area where developers are working on new or modified workflow definitions. You can achieve this separation by defining an isolated region for each area. There is no limit to the number of isolated regions you can define; however, performance considerations impose a limit on the number of isolated regions running concurrently because:
While the target maximum number of isolated regions running is five, if you have memory allocated to processes other than to Process Service or if you do not have the physical memory necessary on the server, performance degradation can result with fewer than five isolated regions running. The amount of memory needed per isolated region is dependent on many factors, including work item BLOb size and workflow complexity. To create an isolated region
NOTE Isolated region 0 exists in every VWService; it contains system data and is reserved for system software use.
