Inferring application type based on input-output characteristics of application storage resources

A computer system for inferring a type of an application to which a storage volume is associated, the computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• and
• program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• program instructions to determine at least one characteristic of a plurality of characteristics of storage volume operational metrics for each storage volume of a storage volume group associated with an application, wherein the at least one characteristic includes a pattern of input-output (I/O) of a storage volume;
• program instructions to create a plurality of clusters of storage volumes by utilizing unsupervised machine learning techniques to the at least one characteristic of the plurality of characteristics of storage volume operational metrics, wherein a first cluster of the plurality of clusters includes storage volumes that have a similar attribute of the at least one characteristic that includes a pattern of input-output, and excludes storage volumes that lack the similar attribute of the at least one characteristic that includes the pattern of input-output;
• program instructions to generate a label for each of the storage volumes of the first cluster of the plurality of clusters, which corresponds to the similar attribute of the at least one characteristic of the plurality of characteristics of each storage volume of the first cluster, and generating a label for each of the storage volumes of each cluster of the plurality of clusters, such that a particular label corresponds to storage volumes of a particular cluster having an attribute of a particular characteristic of the at least one characteristic that includes a pattern of input-output;
• program instructions to assign one or more labels to each storage volume of the storage volume group associated with the application, wherein each label of the one or more labels corresponds to a cluster of the plurality of clusters, and each storage volume of the storage volume group is included in one or more clusters by the unsupervised machine learning determining that a storage volume has an attribute of the at least one characteristic corresponding to a cluster of the one or more clusters;
• program instructions to receive at least one template of storage volume characteristics of known application types, wherein each template includes a set of labels that are based on the storage volume characteristics associated with a known application type;
• and
• program instructions to infer a type of application associated with the storage volume group, based on a best-fit match of a combination of the one or more labels of each storage volume of the storage volume group to a set of labels that are associated with the at least one template of storage volume characteristics of known application types.
