Abstract: A method for controlling the use of a computing resource by multiple tenants in database as a service (DBaaS), includes: intercepting 410 a task that is to access a computer resource, the task being an operating system process or thread; identifying 420 a tenant that is in association with the task from the multiple tenants; determining 430 other tasks of the tenant that access the computing resource; and. Controlling 440 the use of the computing resource by the task. so that the total amount of usage of the computing resource by the task and. the other tasks will not exceed the limit of usage of the computing resource for the tenant. The computing resource may be central processing unit (CPU) and its usage may be controlled by calculating available time slices of CPU scheduling, and allocating time slices for execution to the task. The computing resource may be memory, its usage being controlled by allocating memory for the task from memory space reserved for the tenant.
