Power consumption estimating device, power consumption estimation system, and power consumption estimation method

A power consumption estimation system in which a node cluster including a plurality of nodes, a cluster managing device that manages the node cluster, and a client terminal that requests the node cluster to execute an application are connected via a communication network, wherein

• the cluster managing device includes a power consumption estimating device including
• a metadata database that stores past application metadata related to each of past applications executed on the node cluster,
• a power consumption database including power consumption information representing power consumption of the past applications,
• a power consumption estimating section that estimates power consumption of an estimation target application, and
• an execution managing section that manages an application to be deployed on the node cluster,
• the power consumption estimating section
• acquires an application manifest including information about the estimation target application from the client terminal,
• extracts target application metadata which is metadata related to the estimation target application from the application manifest,
• calculates a degree of similarity of the target application metadata to the past application metadata stored in the metadata database,
• in a case where there is a similar application having a calculated degree of similarity which satisfies a predetermined degree-of-similarity criterion in the past applications, extracts, from the power consumption database, first power consumption information corresponding to the similar application, and
• generates the first power consumption information as a first power consumption estimation result representing a power consumption estimate of the estimation target application, and
• the execution managing section
• determines a deployment destination node to be a deployment destination of the estimation target application from the node cluster on a basis of the first power consumption estimation result, and
• deploys the estimation target application on the deployment destination node.

A power consumption estimation method for estimating power consumption of an estimation target application to be deployed on a node cluster including a plurality of nodes, the power consumption estimation method comprising:

• a step of acquiring an application manifest including information about the estimation target application;
• a step of extracting, from the application manifest, target application metadata which is metadata related to the estimation target application;
• a step of converting the target application metadata into a metadata vector in a vector format by using one-hot encoding means;
• a step of calculating a degree of similarity of the metadata vector to past application metadata related to each of past applications executed on the node cluster;
• a step of, in a case where there is a similar application having a calculated degree of similarity which satisfies a predetermined degree-of-similarity criterion in the past applications, specifying first power consumption information corresponding to the similar application;
• a step of generating the first power consumption information as a first power consumption estimation result representing a power consumption estimate of the estimation target application;
• a step of determining a deployment destination node to be a deployment destination of the estimation target application from the node cluster on a basis of the first power consumption estimation result;
• and
• a step of deploying the estimation target application on the deployment destination node.
