In some embodiments, method 300 is a method of determining qualified server clusters of a plurality of server clusters based on resource requirements of an application, selecting a working set of server clusters by calculating scores of the qualified server clusters, calculating a statistical metric of two or more subsets of the resource requirements, ranking the working set of server clusters by mapping the statistical metric to infrastructure resources of each server cluster of the working set of server clusters, and outputting a list of the ranked server clusters to a user. In some embodiments, at least portions of method 300 are performed by resource manager 215 and/or orchestrator 211.
In some embodiments,
Method 300 includes exemplary operations, but the operations are not necessarily performed in the order shown. Operations may be added, replaced, changed order, and/or eliminated as appropriate, in accordance with the spirit and scope of disclosed embodiments.
In operation S301 of method 300, cumulative resource requirements 212 of application 260 including plurality of pods Pod-1, Pod-2, . . . Pod-r are received. In some embodiments, cumulative resource requirements 212 are received from service catalog 213 by resource manager 215.
In some embodiments, receiving cumulative resource requirements 212 of application 260 includes receiving cumulative resource requirements 212 in response to receiving a user instruction from user 250 by orchestrator 211, the user instruction including an identifier of application 260.
In operation S302 of method 300, a subset of server clusters of plurality of server clusters 220, 230, . . . 240 is determined based on cumulative resource requirements 212. Each server cluster of plurality of server clusters 220, 230, . . . 240 includes nodes, each node includes a set of infrastructure resources represented in server cluster database 217, and determining the qualified server clusters includes comparing an aggregate of the sets of infrastructure resources of each server cluster to cumulative resource requirements 212. Determining that a server cluster is a qualified server cluster includes concluding that the corresponding aggregate of the sets of infrastructure resources is greater than or equal to cumulative resource requirements 212.
In some embodiments, determining the subset of server clusters includes, prior to determining the qualified server clusters, filtering server clusters 220, 230, . . . 240 by matching one or more application-related elements, e.g., tags, location indicators, data center types, or the like, with one or more corresponding server cluster features represented in server cluster database 217. In some embodiments, matching the one or more elements includes receiving at least one element from user 250. In some embodiments, matching the one or more elements includes receiving at least one element from service catalog 213.
In operation S303 of method 300, a working set of server clusters is selected by calculating scores of the server clusters of the subset of server clusters 220, 230, . . . 240. In some embodiments, selecting the working set of server clusters is referred to as a worst-fit operation.
Calculating the score includes summing differences between server cluster capacity and cumulative resource requirements 212 for each requirement of a plurality of requirements of cumulative resource requirements 212. In some embodiments, summing the differences includes calculating a score as
Score=Σd∈D(Cd−Rd)/Cd (1)
where C=allocatable cumulative (aggregate) capacity of the cluster, R=requested cumulative resources for the application, and D={vCPU, GPU, RAM, STORAGE_SSD, STORAGE_HDD}. In this non-limiting example, vCPU corresponds to a processor requirement/capability, GPU corresponds to a graphical processor requirement/capability, RAM corresponds to a memory requirement/capability, STORAGE_SSD corresponds to an SSD storage requirement/capability, and STORAGE_HDD corresponds to an HDD storage requirement/capability.
The scores for each sever cluster of the subset of server clusters are sorted in descending order and normalized to a score of 100 in some embodiments. Selecting the working set of a number W of server clusters of the subset of server clusters is performed by selecting W server clusters having the highest scores.
In some embodiments, the number W is predetermined, e.g., stored by resource manager 215. In some embodiments, the number W is determined during execution of operation S303, e.g., based on available resources. In some embodiments, the number W is received from user 250 by resource manager 215. As the number W increases, both execution time and accuracy of various operations of method 300, e.g. operations S304 and S305, increase.
In operation S304 of method 300, a statistical metric of two or more subsets of resource requirements corresponding to pods of the plurality of pods Pod-1, Pod-2, . . . Pod-r is calculated. In some embodiments, calculating the statistical metric of two or more subsets of resource requirements corresponding to pods is referred to as a window operation.
Calculating the statistical metric includes dividing the plurality of pods Pod-1, Pod-2, . . . Pod-r into the two or more subsets (also referred to as groups or windows), each group including a number K of pods. In some embodiments, the number K is predetermined, e.g., stored by resource manager 215. In some embodiments, the number K is determined during execution of operation S304, e.g., based on available resources. In some embodiments, the number K is received from user 250 by resource manager 215. As the number K increases, execution time of various operations of method 300, e.g., operation S304, decreases and accuracy decreases.
For each group of pods of application 260, calculating the statistical metric includes calculating a normalized score based on the cumulative requirements of the pods of each group for each of two or more resource requirements of the cumulative resource requirements, e.g., cumulative resource requirements 212. Normalization of the scores is based on maximum resource requirements.
In a non-limiting example of a group including pods A, B, and C, pod A has a requirement of 4 vCPU cores and 10 GB RAM, pod B has a requirement of 6 vCPU cores and 5 GB RAM, and pod C has a requirement of 3 vCPU cores and 8 GB RAM. In this example, normalization is thereby based on a maximum vCPU requirement=6 and a maximum RAM requirement=10, with the scores given by
Normalized score of Pod A=4/6+10/10=1.6667 (2)
Normalized score of Pod B=6/6+5/10=1.5 (3)
Normalized score of Pod C=3/6+8/10=1.3 (4)
In some embodiments, the pods are sorted in ascending score order, e.g., for the purpose of computational efficiency. In this example, the pods would be sorted in the order of Pod C, Pod B, and Pod A.
Calculating the statistical metric includes, for each group of pods, calculating one of a minimum, a maximum, a mean, or an average of each requirement of the plurality of requirements of cumulative resource requirements 212. The multi-dimensional metric is then used for comparisons to the available resources on the nodes of the working set of server clusters as discussed below with respect to operation S305.
In some embodiments, the choice of minimum, maximum, mean, or average is a predetermined choice. In some embodiments, the choice of minimum, maximum, mean, or average is determined during execution of operation S304, e.g., based on available resources. In some embodiments, the choice of minimum, maximum, mean, or average is received from user 250 by resource manager 215. In some embodiments, the choice of minimum or average corresponds to a best effort check. In some embodiments, the choice of maximum or mean corresponds to a higher quality computation requiring more time than the choice of minimum or average.
In operation S305 of method 300, the working set of server clusters is ranked by mapping the statistical metric to the plurality of nodes of each server cluster of the working set of server clusters 220, 230, . . . 240.
Mapping the statistical metric to the plurality of nodes of each server cluster of the working set of server clusters includes evaluating the server clusters of the working set of server clusters in the ascending score order discussed above. For each server cluster, the evaluation includes sequentially performing an evaluation for each group of pods based on the statistical metric discussed above. At a first node, the statistical metric of a first group of pods is compared to the available resources and, if the available resources are greater or equal to those of the statistical metric, the first group of pods is determined to be capable of being assigned to the first node. If not, the evaluation continues to each additional node until available resources are identified or the server cluster is determined to be unusable for receiving application 260.
In some embodiments, the nodes of a given server cluster are first filtered by comparing the resource availability to the statistical metric to each node and passing only those nodes that have available resources greater than or equal to the statistical metric.
In some embodiments, the filtered (in some embodiments) nodes are sorted according to a worst fit or best fit hierarchy. In some embodiments, the groups of pods are assigned to nodes using a first fit operation in which a first match between a given group of pods and a given node is sufficient for the group of pods to be assigned to the node.
After a group of pods is assigned to a node, the node is flagged as unavailable, and the evaluation continues until all groups of pods have been assigned to a node in the corresponding server cluster or the server cluster is determined to be unusable. A non-limiting example of a node-level mapping operation is provided below: Initialize a evaluated_node_set=null,
For each window:
In the example above, mapping the statistical metric to the plurality of nodes of each server cluster of the working set of server clusters includes calculating Num_Pods_Estimate (Cnode/M) all dimension of resources {vCPU, GPU, RAM, STORAGE_SSD, STORAGE_HDD} and using the minimum integer value. For example, M=(4 vCPU, 10 GB RAM), C=(38 vCPU, 150 GB RAM), C/M=(9.5, 15), and Cnodei/M=floor(Min(C/M))=9.
In the example above, adding the node to evaluated_node_set ensures that the same node is not repeated for multiple groups.
Mapping the statistical metric to the plurality of nodes of each server cluster of the working set of server clusters continues by repeating the node-level mappings for each server cluster of the working set of server clusters. Each usable server cluster is retained in the working set and, the working set retains the server cluster order established in operation S303.
In operation S306 of method 300, list 219 of ranked server clusters of server clusters 220, 230, . . . 240 is output by orchestrator 211 to user 250. Outputting the list of ranked server clusters includes outputting the list having the number of server clusters discussed above.
Outputting the list of ranked server clusters includes the list including the highest ordered server clusters in the working set of server clusters corresponding to the number of server clusters.
In operation S307 of method 300, application 260 is deployed by orchestrator 211 on a server cluster selected from list 219 by user 250.
In operation S308 of method 300, server cluster database 217 is updated by resource manager 215 based on deployment of application 260 on the selected server cluster of server clusters 220, 230, . . . 240.
In some embodiments, one or more of operations S310-S308 are repeated, e.g., corresponding to various operations being performed over a span of time during which data in server cluster database 217 is repeatedly updated such that results of performing operations S302-S306 are potentially affected.
By executing some or all of the operations of method 300, a device, e.g., device 210 including orchestrator 211, is capable of automatically determining qualified server clusters of a plurality of server clusters based on resource requirements of an application, selecting a working set of server clusters by calculating scores of the qualified server clusters, calculating a statistical metric of two or more subsets of the resource requirements, ranking the working set of server clusters by mapping the statistical metric to infrastructure resources of each server cluster of the working set of server clusters, and outputting a list of the ranked server clusters to a user, the list being usable for deploying the application on a selected server cluster. A system including the device, e.g., system 200 including device 210, is thereby capable of functioning to host and execute multiple software applications more efficiently than systems that function based on other approaches.
