摘要
Managing microservice changes and performing related analytics can include generating a plurality of process instance representations. Each process instance representation can be generated based on a corresponding process path that comprises an ordered sequence of operations that are performed by a process using multiple microservices. A microservices network representation can be constructed based on the plurality of process instance representations, each element of the microservices network corresponding to an interface between a pair of the microservices. Based on the microservices network representation, a relative frequency can be determined for each of the microservices, each relative frequency corresponding to a likelihood that a change in a microservice will affect the performance of at least one process using at least one of the microservices.

This disclosure relates to software development and operations, and more particularly, to monitoring and maintaining resiliency of microservices and other networked components that provide functions within process instances.
Microservices are software constructs that can be used to build software applications by breaking down each application into smaller, independently deployable services that are not dependent, for example, upon a specific coding language. Using microservices, a large complex application can be divvied up into smaller building blocks of executables that when recomposed provide the functionality of a large scale, highly complex application.
In one or more embodiments, a method includes generating a plurality of process instance representations, wherein each process instance representation is generated based on a corresponding process path comprising an ordered sequence of operations performed by a process using at least one of a plurality of microservices. The method also includes constructing a microservices network representation based on the plurality of process instance representations, wherein each element of the microservices network corresponds to an interface between a pair of microservices. Additionally, the method includes determining based on the microservices network representation a relative frequency for each of the plurality of microservices, each relative frequency corresponding to a likelihood that a change in a microservice will affect the functioning of at least one process using at least one of the plurality of microservices.
