A pervasive environment for systemising innovative services in knowledge-intensive firms

In this paper, we propose an approach to model KIBS firm activities as digital ecosystem of services in a distributed environment supported ICT. In particular, we present a generic service system architecture with respect to Everything as a Service (*aaS) architecture to provide digital services in pervasive environment. To achieve interoperability, we introduce a service–based middleware relying on service characteristics and service lifecycles. The middleware enables operational and management features to achieve secure, proactive, and context–aware e–services. An important aspect of our approach is the ontological description of various components and the management of business activities with business rules.
