Enterprise IT infrastructure incurs many costs ranging from hardware costs and software licenses/maintenance costs to the costs of monitoring, managing, and maintaining IT infrastructure. The recent advent of cloud computing offers some tangible prospects of reducing some of those costs; however, abstractions provided by cloud computing are often inadequate(More)
The Web Services paradigm is a simple model for building web-wide distributed systems using XML and HTTP. However, as the use of this technology expands to include Grid and Enterprise computing, the requirement for higher qualities of service becomes important. To address these requirements, we propose a pluggable framework for using Web services components(More)
We examine the use of Federated Identity and Access Management (FIAM) approaches for the Internet of Things (IoT). We look at specific challenges that devices, sensors and actuators have, and look for approaches to address them. OAuth is a widely deployed protocol -- built on top of HTTP -- for applying FIAM to Web systems. We explore the use of OAuth for(More)
SOA proposes an architecture that composes many services together in a loosely coupled manner, and those services may provide a wide spectrum of features like implementing Business Logic, supporting Service Orchestration, Service Mediation, and Eventing, etc. Each user would, typically, choose a subset of these features and build his architecture on them.(More)
The rapid growth of small Internet connected devices, known as the Internet of Things (IoT), is creating a new set of challenges to create secure, private infrastructures. The purpose of this paper is to review the current literature on the challenges and approaches to security and privacy in the Internet of Things, with an especial focus on how these(More)
In this paper we outline the challenges of Web API management in Internet of Things (IoT) projects. Web API management is a key aspect of service-oriented systems that includes the following elements: metadata publishing, access control and key management, monitoring and monetization of interactions, as well as usage control and throttling. We look at how(More)

The DEBS Grand Challenge is an annual event in which different event-based systems compete to solve a real-world problem. The 2014 challenge is to demonstrate scalable real-time analytics using high-volume sensor data collected from smart plugs over a one and a half month period. This paper aims to show how a general-purpose commercially available(More)
