'''Virtual resource partitioning''' ('''VRP''') is an [[operating system-level virtualization]] technology that allocates computing resources (such as [[CPU]] & [[I/O]]) to transactions. Conventional virtualization technologies allocate resources on an [[operating system]] ([[Windows]], [[Linux]]...) wide basis. VRP works 2 levels deeper by allowing regulation and control of the resources used by specific transactions within an application.<ref>{{

In many computerized environments, a single user, application, or transaction can appropriate all server resources and by that, affect the quality of service & user experience of other active users, applications or transactions. For example, a single report in a [[data warehouse]] environment can monopolize data access by demanding large amounts of data. Similarly, a CPU-bound application may consume all server processing power and starve other activities.
