UCC: UML profile to cloud computing modeling: Using stereotypes and tag values

Abstract

Today cloud computing has become one of the common technologies that most of the companies want to migrate their legacy systems or deploy their new system to it. Besides modeling the system, software designers need to model the deployment infrastructure, which their system will be deployed on it. In this paper first of all we presented and categorized the requirements of modeling cloud and then illustrated how the software designer can use the advantages of UML's extendibility to model the deployment of cloud computing systems. By using stereotypes and tag values, it is possible to define a meta-model which is suitable for modeling the system deployed in cloud computing. We show that by using the UML profile, it's possible to model the infrastructures and instances of the cloud. Also it's probable to cover all the requirements that the software designer needs to model the cloud computing. It is concluded that it is important to use a standard modeling language to model the cloud, which makes it possible to model and test the whole system with a unified language. The standard languages such as UML reduce the cost required for understanding and designing the cloud computing's model. It's also possible to use this model in MDA (Model Driven Architecture) to understand and test the system's behavior in the cloud computing before deploying it in the cloud.

Profiling SLAs for cloud system infrastructures and user interactions

“…Infrastructure denotes whether the work provides the mechanisms to model a cloud computing infrastructure. In this case, besides the current work, only Kamali, Mohammadi & Barforoush (2014) through UML profiles and Bergmayr et al (2014) via the CAML language support modeling infrastructures. User interaction indicates whether the proposal supports modeling the communications between the users and the cloud service provider.…”

“…Regarding cloud modeling, different UML profiles have been proposed for modeling multiple aspects of a cloud system. Kamali, Mohammadi & Barforoush (2014) present a UML profile to model the deployment of a system in the cloud. It allows the modeling of instances and the infrastructure offered as a service.…”

“…Specifically, the former indicates whether the proposal analyzed provides some type of pricing scheme. As can be seen, all the papers reviewed except Kamali, Mohammadi & Barforoush (2014) provide it. The latter shows whether the approaches are aimed at enhancing the profits of the cloud service provider.…”

“…With this goal in mind, the modeling and analysis of cloud systems can be a powerful tool for cloud providers to manage their resources, increase their profits, and be more competitive. Thus, we have defined a UML 2.5 parameterized profile, named CloudCost, to model the architecture and interactions of a cloud system based on Service Level Agreements (SLAs) (Khan, 2016). The Unified Modeling Language (UML) (OMG, 2017) is one of the most widely recognized and used modeling languages in this field.…”

A service-oriented cloud modeling method and process

“…For this reason, it is not easy to use CAML in reality. Kamali et al [11] develops cloud applications by identifying and designing nine requirements for designing, executing and managing cloud applications. As this method is limited to deployment modeling only, this does not support the overall modeling process for cloud applications.…”
