This paper presents the architecture for a Base, a clustered environment for building and executing highly available, scalable, but exible and adaptable infrastructure services. Our architecture has three organizing principles: addressing all of the diÆcult service faulttolerance, availability, and consistency problems in a carefully controlled environment, building that environment out of a co...

This paper addresses issues related to how to enable broadest possible innovative activities by infrastructural technology design. In this paper, we focus on the development of high level services based on mobile telecommunication technologies which we for matters of simplicity term the development of a Mobile Internet. The focus of our analysis is how features of the technology itself enable o...

State-of-the-art security mechanisms are often enforced in isolation from each other, which limits the kinds of policies that can be enforced in distributed and heterogeneous settings. More specifically, it is hard to enforce application-level policies that affect, or use information from multiple distributed components. This paper proposes the concept of a Security Service Bus (SSB), which is ...

This paper introduces a new project, InfraWatch, that demonstrates the many challenges that a large complex data analysis application has to offer in terms of data capture, management, analysis and reporting. The project is concerned with the intelligent monitoring and analysis of large infrastructural projects in the public domain, such as public roads, highways, tunnels and bridges. As a demo...
