Abstract

Disclosed aspects manage a shared pool of configurable computing resources. A set of scaling factor data is monitored. The set of scaling factor data is related to a workload on a configuration of the shared pool of configurable computing resources. A set of workload resource data associated with the workload is ascertained. Using the set of scaling factor data and the set of workload resource data, a triggering event is detected. In response to detecting the triggering event, a configuration action (with respect to the configuration of the shared pool of configurable computing resources) is performed.

Claims

1. A system of managing a shared pool of configurable computing resources, the system comprising:

a memory having a set of computer readable computer instructions, and

a processor for executing the set of computer readable instructions, the set of computer readable instructions including;

collecting a set of scaling factor data related to an active workload on a configuration of the shared pool of configurable computing resources, wherein the set of scaling factor data includes an actual number of transactions per time period being processed;

ascertaining a set of workload resource data associated with the active workload, wherein the set of workload resource data includes a hardware configuration template specifying a processor requirement and a memory requirement for an expected number of transactions per time period to be processed;

computing, by subtracting the actual number of transactions per time period from the expected number of transactions per time period, a transaction per time period difference value;

comparing the transaction per time period difference value to a transaction per time period difference threshold to determine whether the transaction per time period difference value exceeds the transaction per time period difference threshold;

detecting, in response to a determination that the transaction per time period difference value exceeds the transaction per time period difference threshold, a triggering event; and

performing, in response to detecting the triggering event, a configuration action with respect to the configuration of the shared pool of configurable computing resources, wherein the configuration action includes;

reconfiguring the configuration of the shared pool of configurable computing resources.

2. The system of claim 1, further comprising:

waiting, in response to collecting the set of scaling factor data related to the active workload, for a temporal period; and

collecting, in response to waiting for the temporal period, the set of scaling factor data related to the active workload.

3. The system of claim 1, wherein the set of scaling factor data related to the active workload is collected in response to a usage event.

4. The system of claim 3, wherein the usage event includes a usage change exceeding a threshold with respect to the set of scaling factor data related to the active workload on the configuration of the shared pool of configurable computing resources.

5. The system of claim 1, wherein the set of scaling factor data is selected from a group consisting of:

a set of transaction processing scaling factor data, a set of user access scaling factor data,

a set of entity storage scaling factor data,

a set of product usage scaling factor data, and

a set of provider-defined scaling factor data which indicates one or more target scaling goals for the active workload.

6. The system of claim 1, wherein the configuration is selected from a group consisting of:

a configuration of a set of processing resources,

a configuration of a set of memory resources,

a configuration of a set of disk resources, and

a configuration of a set of virtual machines.

7. The system of claim 1, wherein detecting, using the set of scaling factor data and the set of workload resource data, the triggering event includes:

identifying a trend in the set of scaling factor data.

8. The system of claim 1, wherein ascertaining the set of workload resource data associated with the active workload includes:

retrieving, from a registry, the set of workload resource data indicated by a workload provider, wherein the set of workload resource data includes a configuration template for resource configurations.

9. The system of claim 8, further comprising:

storing the configuration template as a flavor having a processing component and a memory component;

storing, a first mapping of the flavor to a range of expected users;

storing, a second mapping of the flavor to a range of expected transactions; and

coupling the flavor mapped with the range of expected users and range of expected transactions with a workload identifier.

10. The system of claim 9, wherein the workload identifier indicates:

a required storage attachment technology,

a number of paths to storage for redundancy and throughput, and

a number of Input/Output Operations Per Second (IOPS).

11. The system of claim 1, wherein the configuration action includes:

waiting for a temporal period; and

reconfiguring, in response to waiting for the temporal period, the configuration of the shared pool of configurable computing resources.

12. The system of claim 1, further comprising:

resizing, to reconfigure the configuration of the shared pool of configurable computing resources, one or more virtual machines.
