Enabling real-time testing of on-demand infrastructure
View Patent ↗Provided are techniques for demonstrating the efficiency and effectiveness of a customer's information technology (IT) system and applications operating in a shared IT, or electronic business on-demand, environment. A test suite mimics hypothetical settings in an on-demand services environment ( 129 ) and then determines how the settings affect the allocation of resources in the on-demand services environment ( 129 ). The calculated allocation of resources is then compared to one or more service level agreements (SLAs) in order to determine compliance with a particular SLA.
1. A method for managing a service level agreement, the method comprising:
receiving specification of a resource profile, corresponding to a dynamically allocated subset of computing resources, based on a first specified service level agreement;
comparing, by one or more processors, a predetermined, projected demand profile to an actual demand profile;
simulating, by the one or more processors, based upon the comparing, processing of the projected demand profile using the resource profile to determine a service level result; and
determining that the service level result does not represent processing the predetermined, projected demand profile at an expected service level corresponding to the first specified service level agreement; and, in response to the determining,
increasing one or more resource allocations in the dynamically allocated subset of computing resources to produce a modified resource profile;
repeating the simulating and the determining using the modified resource profile; and
generating, by the one or more processors, a second service level agreement, wherein the second service level agreement is based upon the modified resource profile and processes the workload profile at the expected service level.
2. The method of claim 1 , wherein the projected demand profile includes scheduling information and the simulating incorporates the scheduling information in the processing.
3. The method of claim 1 , wherein the subset of computing resources is one or more of a resource list, the resource list comprising:
allocated processing resources;
memory resources; and
communication bandwidth.
4. The method of claim 1 , wherein the specified service level includes a base resource allocation, a maximum resource allocation, resource costs and rules for dynamically reallocating the resources based upon workload demand.
5. The method of claim 1 , further comprising determining a cost associated with meeting the service level demand.
6. An apparatus for managing a service level agreement, the apparatus comprising:
one or more processors;
a memory, coupled to the one or more processors; and
logic, stored on the memory and executed on the one or more processors, for:
receiving specification of a resource profile, corresponding to a dynamically allocated subset of computing resources, based on a first specified service level agreement;
comparing, by one or more processors, a predetermined, projected demand profile to an actual demand profile;
simulating, by the one or more processors, based upon the comparing, processing of the projected demand profile using the resource profile to determine a service level result; and
determining that the service level result does not represent processing the predetermined, projected demand profile at an expected service level corresponding to the first specified service level agreement; and, in response to the determining,
increasing one or more resource allocations in the dynamically allocated subset of computing resources to produce a modified resource profile;
repeating the simulating and the determining using the modified resource profile; and
generating, by the one or more processors, a second service level agreement wherein the second service level agreement is based upon the modified resource profile and processes the workload profile at the expected service level.
7. The apparatus of claim 6 , wherein the projected demand profile includes scheduling information and the simulating incorporates the scheduling information in the processing.
8. The apparatus of claim 6 , wherein the subset of computing resources is one or more of a resource list, the resource list comprising:
allocated processing resources;
memory resources; and
communication bandwidth.
9. The apparatus of claim 6 , wherein the specified service level includes a base resource allocation, a maximum resource allocation, resource costs and rules for dynamically reallocating the resources based upon workload demand.
10. The apparatus of claim 6 , the logic further comprising logic for determining a cost associated with meeting the service level demand.
11. A computer programming product for managing a service level agreement, comprising a non-transitory computer-readable storage medium having program code embodied therewith, the program code executable by a plurality of processors to perform a method comprising:
receiving specification of a resource profile, corresponding to a dynamically allocated subset of computing resources, based on a first specified service level agreement;
comparing, by one or more processors, a predetermined, projected demand profile to an actual demand profile;
simulating, by the one or more processors, based upon the comparing, processing of the projected demand profile using the resource profile to determine a service level result; and
determining that the service level result does not represent processing the predetermined, projected demand profile at an expected service level corresponding to the first specified service level agreement; and, in response to the determining,
increasing one or more resource allocations in the dynamically allocated subset of computing resources to produce a modified resource profile;
repeating the simulating and the determining using the modified resource profile; and
generating, by the one or more processors, a second service level agreement wherein the second service level agreement is based upon the modified resource profile and processes the workload profile at the expected service level.
12. The computer programming product of claim 11 , wherein the projected demand profile includes scheduling information and the simulating incorporates the scheduling information in the processing.
13. The computer programming product of claim 12 , wherein the subset of computing resources is one or more of a resource list, the resource list comprising:
allocated processing resources;
memory resources; and
communication bandwidth.
14. The computer programming product of claim 11 , wherein the specified service level includes a base resource allocation, a maximum resource allocation, resource costs and rules for dynamically reallocating the resources based upon workload demand.
15. The computer programming product of claim 11 , the logic further comprising logic for determining a cost associated with meeting the service level demand.
