CONTAINER SYSTEM VISIBILITY & MODELEXTRACTION

Abstract: The development of applications that use microservice architecture patterns is increasingrapidly, and this architecture is proven to be successful in many different areas, especiallyin cloud computing. The reason microservices and cloud computing are a great matchis the possibility of scaling and deploying individual services, which positively affects thecost and utilization. This architecture pattern includes some challenges for the devel-opers, such as placement optimisation and knowledge about how the applications aredeployed.This study intends to clarify how the applications in a multi-cluster environment are de-ployed. A service model was created, describing how applications built with microservicearchitecture patterns communicate to each other and which microservices the applicationcontains. More specifically, this can be seen as the first step of placement optimisationthat will be developed in the future. The test cases used to produce the service modelshave various characteristics, such as control planes, where applications were deployed,and numbers of replicas. These kinds of characteristics were varied so that the servicemodels could be relied on and such that the model created works independent of howthe deployment model is created. The created service models show that the applicationtopology is not restricted for the reverse engineering method to work. Independent ofthe number of control planes or replicas, this method worked. Furthermore, the servicemodels created for each test case gave the correct outcome for each application regardingmicroservices and the connections between each microservice.
