Isolating resources and performance in a database management system

A computer-implemented method for determining whether a tenant is allocated a reserved amount of server resources comprising:

• providing a reservation of a reserved amount of a server resource for a tenant in a multi-tenant environment, the server resource including each of a central processing unit (CPU) utilization allocation, a minimum guaranteed amount of working memory, a minimum guaranteed amount of input/output (I/O) throughput, a minimum network bandwidth;
• receiving, from the tenant, a request to utilize the server resource;
• determining, based at least in part on the request, that the tenant has sufficient demand to consume the reserved amount of the server resource;
• determining an actual amount of the server resource actually allocated to the tenant while servicing the request to utilize the server resource;
• comparing the actual amount and the reserved amount of the server resource;
• and
• determining that the tenant is not allocated the reserved amount of the server resource.

A device configured to determine whether a tenant is allocated a reserved amount of server resources and provide for accountability of the server, the device comprising:

• one or more processors;
• and
• one or more computer-readable media storing instructions that, when executed by
• the one or more processors, cause the computing device to:
• provide a reservation of a reserved amount of a server resource to a tenant, the reserved amount of a server resource including at least a minimum guaranteed central processing unit (CPU) utilization allocation, a minimum guaranteed amount of working memory, and a minimum guaranteed amount of input/output (I/O) throughput;
• receive a request to utilize the server resource;
• determine, based at least in part on the request, a workload for the tenant;
• determine that the workload of the tenant has a sufficient demand to consume the guaranteed CPU utilization;
• determine, based at least in part on receiving the request, that a server does not allocate the reserved amount of the server resource to the tenant;
• and
• establish an accountability of the server for the tenant.
