Stakeholder Interactions to Support Service Creation in Cloud Computing

Abstract

Abstract-Cloud computing is already a major trend in IT. Cloud services are being offered at application (software), platform and infrastructure levels. This paper presents our initial modeling efforts towards service creation at the infrastructure level. The purpose of these modeling efforts is to understand and reason about the service creation process. The paper presents a conceptual model represented as a UML class diagram, and identifies the interactions between service providers and infrastructure providers that are necessary in order to set up an execution environment and deploy services on top of infrastructure services. Although the models are far from complete, we are confident that they already give us some insight in the service creation process.

Modeling the interactions between cloud service providers

“…An interesting approach is presented in Ref. [11]. Authors propose a conceptual model (represented as a UML class diagram) that enables identification of interactions between service providers and infrastructure providers in order to provide an execution environment and deploy services on top of infrastructure services.…”

Conceptualizing Cloud-Platforms as Service Systems

“…In [25], a first approach for capturing interactions in the context of cloud-services is developed. However, this approach only considers operations for defining services and does not support other kinds of interactions.…”

Robust collaborative services interactions under system crashes and network failures

“…At runtime, each incoming request message triggers a new adapter instance creation and we use the limited EC2 instance type in this evaluation (t1.micro with 1 vCpu and 0.613 GiB memory). However, we expect lower performance overhead when the infrastructure is scalable, like in a cloud environment [103].…”
