Abstract

Complex Cloud applications consist of a variety of individual components that need to be provisioned and managed in a holistic manner to setup the overall application. The Cloud standard TOSCA can be used to describe these components, their dependencies, and their management functions. To provision or manage the Cloud application, the execution of these individual management functions can be orchestrated by executable management plans, which are workflows being able to deal with heterogeneity of the functions. Unfortunately, creating TOSCA application descriptions and management plans from scratch is time-consuming, error-prone, and needs a lot of expert knowledge. Hence, to save the amount of time and resources needed to setup the management capabilities of new Cloud applications, existing TOSCA description and plans should be reused. To enable the systematic reuse of these artifacts, we proposed in a previous paper a method for combining existing TOSCA descriptions and plans or buildings blocks thereof. One important aspect of this method is the creation of BPEL4Chor-based management choreographies for coordinating different plans and how these choreographies can be automatically consolidated back into executable plans. This paper extends the previous one by providing a much more formal description about the choreography consolidation. Therefore, a set of new algorithms is introduced describing the different steps required to consolidate the management choreography into an executable management plan. The method and the algorithms are validated by a set of tools from the Cloud application management ecosystem OpenTOSCA.
