The use of Infrastructure-as-a-Service (IaaS) has become more and more prevalent over the past few years. Many IaaS users face the challenge of managing different services and applications running on different IaaS providers. This requires them to interact with different APIs offered by the different providers, and increases the complexity of managing their services. In this paper, we address this problem by modeling IaaS using the DMTF Common Information Model (CIM) meta-model. Based on this model, a generic IaaS proxy was developed using Web2Exchange to enable users to easily manage services provided by variant IaaS providers in a heterogeneous environment. As an initial case study we have prototyped the unified IaaS proxy with capability to support management of Amazon Elastic Compute Cloud (EC2) service. © 2010 IEEE. Source

Infrastructure-as-a-Service (IaaS) is the most acceptable Cloud Computing delivery model that CIO and IT managers are exploring as they relook at their IT infrastructure. However, the adoption of IaaS faces challenge/concerns such as provider lock-in, reliability, and regulatory compliance for data locality. Our project, Aggregated IaaS Service, addresses this issue by providing a common interface and description of IaaS services across multiple IaaS service provider. We had developed an abstraction model for Iaas services and then provide the interface to the commercial IaaS providers: AWS and GoGrid. The Aggregated IaaS services are exposed to the users through a portal which allow users to subscribe, monitor, and manage the life-cycle of IaaS services from multiple providers. To meet the requirements of the enterprise users the IaaS Aggregator portal have modules such as corporate account management and policy enforcement modules which transform it from a single client user to corporate/company usage of IaaS service from multiple providers. © Copyright 2011 Annual SRII Global Conference.

Cloud Computing has become more and more prevalent over the past few years, and we have seen the emergence of Infrastructure-as-a-Service (IaaS) which is the most acceptable Cloud Computing service model. However, coupled with the opportunities and benefits brought by IaaS, the adoption of IaaS also faces management complexity in the hybrid cloud environment which enterprise users are mostly building up. A cloud management system, Monsoon proposed in this paper provides enterprise users an interface and portal to manage the cloud infrastructures from multiple public and private cloud service providers. To meet the requirements of the enterprise users, Monsoon has key components such as user management, access control, reporting and analytic tools, corporate account/role management, and policy implementation engine. Corporate Account module supports enterprise users' subscription and management of multi-level accounts in a hybrid cloud which may consist of multiple public cloud service providers and private cloud. Policy Implementation Engine module in Monsoon will allow users to define the geography-based requirements, security level, government regulations and corporate policies and enforce these policies to all the subscription and deployment of user's cloud infrastructure. © 2011 IEEE.

The standardization of cloud services makes it possible to have one cloud service management platform for customers to take advantage of their subscriptions from various cloud providers. One immediate benefit lies in the way that enterprise customers may have plenty of choices of available providers, when seeking cloud services to fulfill their criteria, such as price or Service Level Agreement (SLA). However, how to select appropriate cloud offerings in terms of business requirements and company policies becomes challenging and non-trivial, especially when a composition of multiple services are to be chosen for achieving business goals. In this paper, a systematic framework on top of a hybrid cloud management platform is proposed for enterprises to automatically recommend and select cloud services according to business requirements, company policies and standards, and the specifications of cloud offerings. © 2012 IFIP.

A key goal of the Semantic Web is to shift social interaction patterns from a producer-centric paradigm to a consumer-centric one. Treating customers as the most valuable assets and making the business models work better for them are at the core of building successful consumer-centric business models. It follows that customizing business processes constitutes a major concern in the realm of a knowledge-pull-based human semantic Web. This paper conceptualizes the customization of service-based business processes leveraging the existing knowledge of Web services and business processes. We represent this conceptualization as a new Extensible Markup Language (XML) markup language Web Ontology Language-Business Process Customization (OWL-BPC), based on the de facto semantic markup language for Web-based information [Web Ontology Language (OWL)]. Furthermore, we report a framework, built on OWL-BPC, for customizing service-based business processes, which supports customization detection and enactment. Customization detection is enabled by a business-goal analysis, and customization enactment is enabled via event-condition-action rule inference. Our solution and framework have the following capabilities in dealing with inconsistencies and misalignments in business process interactions: 1) resolve semantic mismatch of process parameters; 2) handle behavioral mismatches which may or may not be compatible; and 3) process misaligned rendezvous requirements. Such capabilities are applicable to business processes with heterogeneous domain ontology. We present an architectural description of the implementation and a walk-through of an example of solving a customization problem as a validation of the proposed approach. © 2011 IEEE. Source
