Abstract

A method for determining a deployment configuration of multiple micro services that interact with each other is provided. The method includes the steps of determining a metric describing an amount of communication traffic between at least two of the micro services. Based on the metric, an execution environment may be determined for at least one of the micro services. Deployment information specifying that the at least one micro service shall be deployed on the determined execution environment may be generated.

First claim

What is claimed is:

1. A method for determining a deployment configuration of a plurality of micro services that interact with each other, the method comprising:
determining, by a processor of a computing system, a metric describing an amount of communication traffic between at least two of the plurality of micro services;
determining, by the processor, based on the metric, an execution environment for at least one of the plurality of micro services, wherein determining the execution environment for the plurality of micro services includes: (i) determining one or more pairs of the plurality of micro services whose metric is higher than a predefined threshold, (ii) grouping the one or more pairs into at least one group, and (iii) assigning each group of the at least one group to a respective execution environment, and each of a non-grouped micro services to a respective execution environment;
generating, by the processor, deployment information specifying that the at least one micro service of the plurality of micro services shall be deployed on the determined execution environment; and
deploying one or more new micro services on the execution environment specified by the deployment information.

2. The method of claim 1 , wherein determining the metric comprises executing the at least two micro services, analyzing log data generated by the plurality of micro services and calculating the metric based on the analyzing.

3. The method of claim 1 , wherein determining the execution environment is further based on an amount of available communication resources for data exchange between candidate execution environments on which the plurality of micro services could be deployed.

4. The method of claim 1 , wherein the at least one group comprises one or more micro services.

5. The method of claim 1 , wherein the execution environment is selected from the group consisting of: a computing node, a virtual machine instantiated on a computing node, a software container instantiated on a computing node, a cluster of multiple computing nodes, and a data center.

6. The method of claim 1 , further comprising modifying the deployment of an already instantiated micro service based on the deployment information, the modifying including migrating the already instantiated micro service from an original execution environment, on which the already instantiated micro service is currently running, to a target execution environment specified by the deployment information.

7. The method of claim 1 , wherein the at least one micro service is a new micro service to be added to remaining micro services of the plurality of micro services, the remaining micro services having respective execution environments.

8. The method of claim 1 , wherein the plurality of micro services interact with each other through a network, further wherein the metric is selected from the group consisting of: a network bandwidth capability, a network congestion, a delay, a delay jitter, and a loss rate.

9. A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method for determining a deployment configuration of a plurality of micro services that interact with each other, the method comprising:
determining, by a processor of a computing system, a metric describing an amount of communication traffic between at least two of the plurality of micro services;
determining, by the processor, based on the metric, an execution environment for at least one of the plurality of micro services, wherein determining the execution environment for the plurality of micro services includes: (i) determining one or more pairs of the plurality of micro services whose metric is higher than a predefined threshold, (ii) grouping the one or more pairs into at least one group, and (iii) assigning each group of the at least one group to a respective execution environment, and each of a non-grouped micro services to a respective execution environment;
generating, by the processor, deployment information specifying that the at least one micro service of the plurality of micro services shall be deployed on the determined execution environment; and
deploying one or more new micro services on the execution environment specified by the deployment information.

10. The computer program product of claim 9 , wherein determining the metric comprises executing the at least two micro services, analyzing log data generated by the plurality of micro services and calculating the metric based on the analyzing.

11. The computer program product of claim 9 , wherein determining the execution environment is further based on an amount of available communication resources for data exchange between candidate execution environments on which the plurality of micro services could be deployed.

12. The computer program product of claim 9 , wherein the at least one group comprises one or more micro services.

13. A computer system comprising:
a processor;
a memory device coupled to the processor; and
a computer readable storage device coupled to the processor, wherein the storage device contains program code executable by the processor via the memory device to implement a method for determining a deployment configuration of a plurality of micro services that interact with each other, the method comprising:
determining, by a processor of a computing system, a metric describing an amount of communication traffic between at least two of the plurality of micro services;
determining, by the processor, based on the metric, an execution environment for at least one of the plurality of micro services, wherein determining the execution environment for the plurality of micro services includes: (i) determining one or more pairs of the plurality of micro services whose metric is higher than a predefined threshold, (ii) grouping the one or more pairs into at least one group, and (iii) assigning each group of the at least one group to a respective execution environment, and each of a non-grouped micro services to a respective execution environment;
generating, by the processor, deployment information specifying that the at least one micro service of the plurality of micro services shall be deployed on the determined execution environment; and
deploying one or more new micro services on the execution environment specified by the deployment information.

14. The computer system of claim 13 , wherein determining the metric comprises executing the at least two micro services, analyzing log data generated by the plurality of micro services and calculating the metric based on the analyzing.

15. The computer system of claim 13 , wherein determining the execution environment is further based on an amount of available communication resources for data exchange between candidate execution environments on which the plurality of micro services could be deployed.

16. The computer system of claim 13 , wherein the at least one group comprises one or more micro services.
