Purpose The purpose of this paper is to propose an applicable method for establishing the dynamic inter-organizational collaborations (DIOCs) based on the scrum methodology. Design/methodology/approach The scrum methodology embedded within the context of the DIOC project life cycle was used and adapted to being usable with specific characteristics of the project. Findings In order to succeed in the highly competitive, dynamic and changing business environments, the organizations need to change their view of business practices. The transition from the traditional status of manufacturing to the inter-organizational collaborations can be one of the fundamental changes in the modern business management. The proposed method has the capability to establish DIOCs effectively and efficiently whilst guaranteeing agility, competitiveness, and risk timely management. Originality/value Establishing collaborative alliances via association of various experienced and professional organizations and producing the value-added market’s need services is an effective and efficient solution for survival of SMEs in the current competitive, dynamic and changing business environment. So far, different frameworks, reference models/architectures, and many theoretical discussions have been presented for DIOCs context, but these representations are conceptual, empirical and generic. This paper aims to propose an applicable iterative and incremental method for establishing the DIOC which guarantees the agility and risk timely management of the establishment process and promotes competitiveness of partners.

Cloud Computing is a model of both service delivery and consumption for increasing the capabilities of enterprises dynamically without investing in new infrastructure, training new personnel, or licensing new software. It refers to everything delivered as services over the Internet. Although the benefits of Cloud Computing are evident, security is one of the major issues which hamper the growth of cloud. In this paper, to facilitate identifying the security threats of cloud computing, we Taxonomy the security aspects of cloud computing systems and summarize the main security threats of it. Our taxonomy covers the four domains of cloud computing systems: infrastructure layer, platform layer, application layer and administration.

Abstract-In today's globally networked environment, enterprises need collaborating using Information Technology (IT) and other tools to succeed in this dynamic and heterogeneous business environment. The Global Village Services Reference M odel (GVSRM ) is a model based on SOSA (Service Oriented Strategies and Architectures) ontology for global village services realization. In this model, three architectural abstraction layers have been considered for global village: ‗infrastructure for global village services', ‗global village services provisioning', and ‗using global village services'. Despite of relative completeness of this model, one of its obvious shortcomings is lack of attention to the crucial issue of interoperability in the global village. Based on this model, the grid of global village is comprised of VHGs (Virtual Holding Governance). The VHG is a temporary, scalable, dynamic cluster/association comprising of existing or newly service provider organizations which its aim is satisfying the requirements of global village actors through electronic processes. In this paper, we will propose a federated approach for interoperability among the VHGs of the global village and then improve the GVSRM by adding the corresponding interoperability components to it.
