Model-driven cloud resource management with OCCIware

Abstract

Cloud computing has emerged as the main paradigm for hosting and delivering computing resources as services over Internet. It provides a delivery model for computing resources at infrastructure, platform, and software levels. However, there is a plethora of cloud providers offering different resource management interfaces. Due to this diversity, the consumption, provisioning, management, and supervision of cloud resources are subjected to four key issues, i.e., heterogeneity, interoperability, integration, and portability. To cope with these issues, Open Cloud Computing Interface (OCCI) is proposed as a community-based and open recommendation standard for managing any kind of cloud resources. Currently, only runtime implementations exist for OCCI, and each one targets a specific cloud service model such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). Thus, OCCI lacks an approach to model and execute different OCCI artifacts. Our approach provides a generic modeling framework coupled with a generic runtime implementation. In this article, we propose the OCCIware approach, which represents the first approach to design, validate, generate, implement, deploy, execute, and supervise everything as a service with OCCI. This approach provides OCCIware Studio, the first model-driven tool chain for OCCI. It is built around OCCIware Metamodel, which defines the static semantics for the OCCI standard in Ecore and OCL. In addition, it proposes OCCIware Runtime, the first generic OCCI runtime implementation targeting all the cloud service models (IaaS, PaaS, and SaaS). OCCIware provides a unique and unified framework to manage OCCI artifacts and, at the same time, it represents a factory to build cloud domain-specific modeling frameworks where each framework targets a specific cloud domain. OCCIware has been applied in various cloud domains and use-cases, which validate its applicability.• Model-Driven Managing Everything as a Service with OC-CIware. OCCIware is a model-driven vision to manage XaaS.It allows one to model any type of resources. It provides OCCI users with facilities for designing, editing, validating, generating, implementing, deploying, executing, managing, and supervising XaaS with OCCI.• Generating Cloud Domain-Specific Modeling Frameworks with OCCIware. OCCIware is a factory of cloud domainspecific modeling frameworks. Each generated Cloud Domain-Specific Modeling Studio (CDSMS) is dedicated for a particular cloud domain. Each CDSMS can be used to design configurations which conform to its related domain and hides the generic concepts of OCCI.The OCCIware approach is composed of two main components: OCCIware Studio and OCCIware Runtime. OCCIware Studio is the first model-driven tool chain for OCCI [9]. OC-CIware Studio has been built around OCCIware Metamodel. This metamodel represents a precise definition for OCCI [10]. It defines rigourously the static semantics of the OCCI Core Model [7], the core specification of OCCI, by resolving several identified...

Addressing Semantics Standards for Cloud Portability and Interoperability in Multi Cloud Environment

“…OCCI is an open standard for the efficient management and access of cloud resources by the RESTful API and defines cloud resources through a generic extensible model. The model driven OCCIware approach [68] is composed of OCCIware Studio and OCCIware runtime. The OCCIware approach has to clearly specify the core model that can specify any cloud resources such as IaaS, PaaS, and SaaS and generates a cloud domain model for each domain and maps each domain to a designer.…”

Special Issue on Fog and Cloud Computing for Cooperative Information System Management: Challenges and Opportunities

“…The article (Faiez Zalila et al), entitled "Model-Driven Cloud Resource Management with OCCIware" [2], proposes an OCCIware approach to design, validate, generate, implement, deploy, execute, and supervise everything as a service with Open Cloud Computing Interface (OCCI), where the static semantics for the OCCI standard are defined and different cloud service models are verified.…”

“…We invited research works that provide new solutions, novel methods, or newfound knowledge and results for addressing the above challenges. After a rigorous review process, we accepted 10 submissions, distributed mainly in following groups: i) cloud resource management [1,2,3], ii) heterogeneous data management [4,5], iii) container framework and system [6,7], iv) service and business process techniques [8,9], and v) cloud solution [10].…”

A Modeling Method for Model-Driven API Management

“…In comparison, our work did not aim to generate new API objects from models, but rather to provide a modeling tool that can be used in order to streamline, test and orchestrate web APIs' execution in business processes. In [18] authors describe a tool for managing cloud service ecosystems using the Open Cloud Computing Interface, strengthened by model-driven engineering. In our case, we focused on API ecosystem management that includes services mostly used for retrieving or sending data, while cloud services are mostly used for acquiring superior computing power or storage space.…”
