Recent migration towards the cloud has lead to boom of initiatives that address key issues related to it. One of these issues, integrating various available cloud services while providing automated lifecycle management, was addressed by cloud governance.However, while mostly until now computers and phones were linked to the internet, new devices like tablets, sensors, smart devices (embedded devices) are now making their way into this environment. This, in turn, raises questions related to managing, governing these devices.Similarly to how cloud governance extends SOA governance, this article will detail the way in which IoT governance extends cloud governance. 1

Abstract:The Small and Medium Enterprises benefit now, due to the scale adoption of Cloud Computing, from an emerging market where they can associate and collaborate to form virtual enterprises or virtual clusters, aiming to compete with the large enterprises and provide tailored IT solutions for their customers. However the lack of standardization for the cloud services and technologies leads to a myriad of different components that cannot be easily set to work together in the absence of a real cloud governance solution. Cloud governance acts like a catalyst to allow Small and Medium Enterprises to easily manage and optimize their services infrastructure, and to facilitate collaboration in a clustered or virtual-enterprise environment. We have proposed a Cloud Governance architecture based on mOSAIC's multi-agent Cloud Management solution. The Cloud Governance solution relies on various datastores that are responsible with maintaining and managing a set of crucial data that are used during the cloud governance process . Our paper is focused to analyze and emphasize the requirements that must be fulfilled by different database systems in order to have a reliable storage system and also to suggest a concrete solution.

Cloud computing has made the use of IT services more accessible and cheap. Resources are easily configurable and accessible using networked client devices and are characterised by particular agility and efficiency of use that allows to scale dynamically and on demand. However, owing to the current lack of standards and to the heterogeneity of technologies, users have little flexibility in choosing from alternative providers simultaneously in order to optimise resources at different levels so being affected by the vendor lock-in problem. In this paper, we address the problem of interoperability at IaaS level by proposing an agent abstraction, the vendor agent that is a wrapper to a specific provider technology, and its implementation to support two well-known cloud platforms: Open Nebula and Amazon. This abstraction represents a key driver towards interoperability giving users the opportunity to choose and use services provided by many different cloud vendors.

Thought still at its first steps, cloud governance lays the foundation upon which business innovations can be built. It fills in the gaps left by cloud providers and allows major players on the IT market to be challenged by small and medium-sized enterprises (SMEs) for their share. At the core of cloud governance, its bus enables interaction and communication between various services and governance components. The cloud governance bus is a step forward for the enterprise service bus (ESB) into the cloud environment, addressing data integration and full implementation of enterprise integration patterns. This paper covers current requirements for ESB migration to the cloud environment and proposes a cloud governance architecture that meets the given requirements.
