Cloud computing and RESERVOIR project

The support for complex services delivery is becoming a key point in current internet technology. Current trends in internet applications are characterized by on demand delivery of ever growing amounts of content. The future internet of services will have to deliver content intensive applications to users with quality of service and security guarantees. This paper describes the RESERVOIR project and the challenge of a reliable and effective delivery of services as utilities in a commercial scenario. It starts by analyzing the needs of a future infrastructure provider and introducing the key concept of a service oriented architecture that combines virtualisation-aware grid with grid-aware virtualisation, while being driven by business service management. This article will then focus on the benefits and the innovations derived from the RESERVOIR approach. Eventually, a high level view of RESERVOIR general architecture is illustrated

Towards a hybrid simulation modelling framework for service networks

The increasingly globalized service-centric economy has brought much attention on the concept of service networks. Scientific disciplines, such as management and service oriented computing, have commenced studying on how to design, develop, manage, and govern service networks. What is really needed for service networks to be developed, provisioned and managed in practice, however, are disciplined methods and tools that are able to take into account, tune and reconcile both technical and business considerations. This paper may be seen as a first, yet critical step in realizing the above vision. In particular, this paper explores a hybrid service network simulation approach that is able to analyze, optimize and tune the performance of service networks and their resources, including software services and human operated services. Our holistic, hybrid simulation framework will be firmly grounded on pre-existing simulation techniques that have been widely used in process modelling and simulation

Process-aware information systems for emergency management

Nowadays, Process-aware Information Systems (PAISs) are widely used in many business scenarios, e.g., by government agencies, by insurance companies, and by banks. Despite this widespread usage, the typical application of such systems is predominantly in the context of business scenarios. Nevertheless, emergency management can also benefit from the use of PAISs; for instance, the metaphor of a business process fits very good with the concept of emergency recovery plan. This paper summarizes an invited talk given by the first author for the EMSOA’10 workshop that has been co-located with the ServiceWave 2010 Conference. This paper starts the basic PAIS’ requirements for the domain of emergency management, then it gives an overview of the nowadays’ literature on using PAISs for Emergency Management. Finally, the paper proposes an architecture and a system to support the execution of emergency management processes

The RESERVOIR model and architecture for open federated cloud computing

The emerging cloud computing paradigm is rapidly gaining momentum as an alternative to traditional IT. However, contemporary cloud computing offerings are mostly geared towards Web 2.0 style applications and only recently have begun to address the needs of enterprise-grade solutions, such as support for infrastructure-level SLAs. To address the challenges and deficiencies in the current state of the art, we propose a modular, extensible cloud architecture with intrinsic support for Business Service Management (BSM) and federation of clouds. Our goal is to facilitate an open, service-based, on-line economy, where resources and services are transparently provisioned and managed across clouds on an on-demand basis at competitive costs with high quality of service. We present the vision driving the RESERVOIR project- an architecture that allows providers of cloud infrastructure to dynamically partner with each other to create a seemingly infinite pool of IT resources while fully preserving the autonomy of technological and business management decisions. To this end, RESERVOIR leverages and extends the advantages of virtualization and embeds autonomous management into the infrastructure. At the same time, the RESERVOIR approach aims to achieve a very ambitious goal- creating a foundation for next-generation enterprise-grade cloud computing.

Design for future internet service infrastructures,” in Towards the Future Internet - A European Research Perspective

Abstract. This paper presents current research in the design and integration of advance systems, service and management technologies into a new generation of Service Infrastructure for Future Internet of Services, which includes Service Clouds Computing. These developments are part of the FP7 RESERVOIR project and represent a creative mixture of service and network virtualisation, service computing, network and service management techniques

A Cloud Environment for Data-intensive Storage Services

Abstract — The emergence of cloud environments has made feasible the delivery of Internet-scale services by addressing a number of challenges such as live migration, fault tolerance and quality of service. However, current approaches do not tackle key issues related to cloud storage, which are of increasing importance given the enormous amount of data being produced in today's rich digital environment (e.g. by smart phones, social networks, sensors, user generated content). In this paper we present the architecture of a scalable and flexible cloud environment addressing the challenge of providing data-intensive storage cloud services through raising the abstraction level of storage, enabling data mobility across providers, allowing computational and content-centric access to storage and deploying new data-oriented mechanisms for QoS and security guarantees. We also demonstrate the adde
